property damage, or injuries that occur while using the Performance Computer. Like your car’s speedometer, this device is no more than a measuring instrument, a tool that can be used to measure vehicle performance. Obey all traffic laws on the street. Drive responsibly, and use common sense. ROLLOVER WARNING This device measures G-Forces, but it does not change the laws of physics. Under certain circumstances, almost any vehicle can roll over, causing serious injury or death. Taller vehicles such as SUVs, trucks, and vans are more likely to roll than conventional cars, so even more care needs to be taken with those vehicles. No electronic device can take the place of the driver’s judgment.

many capabilities of your new Performance Computer. This page provides only a basic overview of the instal- lation, features, and capabilities. INSTALLATION 1) Plug into lighter socket Plug the cord into the Performance Computer, and into your car’s lighter socket. The Performance Computer is always “On,” there is no on-off switch. (If your car’s lighter socket is always powered, unplug the Performance Computer when not in use to avoid discharging your car’s battery.) 2) Attach to windshield in center of car Mount the Performance Computer centered between the driver and passenger with the suction cup mount. Make sure the unit is mounted squarely in the car. Do not mount the unit so it is angled toward the driver. Pivot the unit on the bracket until it is approxi- mately level (it is not necessary to be perfectly level). 3) Park on a level surface, then press and release the CALIBRATE button Each time you remount the unit, you must calibrate the G-Meter. (The calibration is stored in memory even if the unit is unplugged, so you don’t need to calibrate again unless you reposition or reinstall the unit.) Quick Start Guide G-METER BUTTON Press and release to select different displays of G-Forces and other data Except when performing timed runs, the unit is nor- mally in the “G-METER” mode, where it can display the acceleration, braking, and cornering G-forces of your car. Press and release to select different G-Meter displays. A good initial choice is G-Meter Option 1, a Bar Graph that shows acceleration and braking forces on the top line, and cornering forces on the bottom line. SETUP MODE Hold the G-METER button to enter Set-Up mode Power-on LED 5 4 TIMED RUN BUTTON Press and release to start a timed run Your car must be stopped before you can perform a timed run (0-to-60, quarter mile, etc.). 1) Press and release the button 2) Wait a few seconds until the display shows “Run READY, Start anytime” 3) Accelerate whenever you are ready. During your run, the unit automatically records and saves complete run data. The yellow LED lights when the unit is in the timed run mode and also when you are reviewing timed runs. UP AND DOWN BUTTONS Press to review timed runs The 10 most recent runs are saved in memory. Press the UP and DOWN buttons whenever you want to re- view these runs.

driver and passenger. The unit must be straight across the car. Do not angle the unit toward the driver! Angle adjustment Pivot the unit on its windshield bracket until it is approximately level. It is important that the unit stays in position during use. If the unit pivots too easily, tighten the large Phillips-head fastener slightly. Calibration • G-Meter: Park on a level surface, then press the CALI- BRATE button to calibrate the G-Meter function. • Timed Run: You do not have to press the calibration button before a timed run. The Performance Computer automatically performs a separate internal calibra- tion before each timed run. Remote Control Cord A convenient way to control your Performance Computer. • Press and release the button to operate the G-Meter function. Press again to change to different display. • Press and hold the button to start a Timed Run. Unit must be mounted squarely in car Mount the unit on the windshield, centered between driver and passenger. The unit must be straight across the car. Do not angle the unit toward the driver! NO! Do not angle the unit. ! ! Unit does not have to be exactly level The unit does not have to be perfectly level side to side, special circuitry automatically compensates for mounting angles up to 30 degrees from level. OK Tilt does not have to be exactly level. The front of the unit does not have to be perfectly level, special circuitry automatically compensates for mount- ing angles up to 30 degrees from level. OK OK OK YES! Mount the unit straight across the car.

When you’re not performing a Timed Run, the Perfor- mance Computer is in the G-Meter Mode, where it can display the acceleration, braking, and cornering forces of your car. These forces are measured in “G’s,” and they are the best way to measure your car’s performance. You’ve felt these forces—when a powerful car “pushes you back in the seat,” when a panic stop presses you for- ward against the seat belt, and when a sharp corner presses you against the door panel. What the G-Meter shows The G-Meter displays the G-Forces exerted by your car, in the plane of the road. On a perfectly level surface, the G-Meter will read zero when your car is not mov- ing, or when it is traveling “steady-state” (not acceler- ating, braking, or turning). However, on hills or sloped surfaces, the G-Meter will show a small G-Force, even when your car is not mov- ing. This shows the force your tires are exerting to keep your car from sliding down the slope. TO SELECT G-METER Press and release the G-METER button to choose the G-Meter mode. Press and release the button again to select different G-Meter display options. To Calibrate the G-Meter, park on a level surface, then press and release the CALIBRATE button. WARNING! This device measures G-Forces, but remember, it does not change the laws of physics. Under certain circum- stances, almost any vehicle can roll over, causing seri- ous injury or death. Taller vehicles such as SUVs, trucks and vans are more likely to roll than conventional cars, so even more care needs to be taken with those ve- hicles. No electronic device can take the place of the driver’s judgment. 9 8 Specifications Accelerometer 2-axis, +2G range, high-resolution digital outputs.

How it works The Performance Computer measures the performance of your car by sensing acceleration forces. An internal precise digital 2-axis accelerometer tracks your car’s acceleration, braking, and cornering forces approximately 200 times each second. A built-in com- puter continuously analyzes this data and calculates corrected G-Forces for the G-Meter operation, and speed and distance data for the Timed Run operation. Your Performance Computer was developed and tested extensively, both at drag strips and using our VBOX professional vehicle testing equipment, the ultra- precise data acquisition system used by auto makers BMW, Honda, and AMG Mercedes; race teams Ford Racing, Roush Industries, Chip Ganassi Racing, and Renault F1; tire manufacturers Michelin, Bridgestone, Goodyear, and Kumho; and car testers at Car and Driver and Automobile Magazines. The result is the most accurate accelerometer-based performance computer available. And it’s the first unit with true one-button operation: Press a single button for calibration, a single button for G-meter operation, a single button to start a timed run, and a single but- ton to review your previous runs.

Press and release the G-METER button as necessary to select “G-METER OPTION 2.” The small numbers on this display show the braking and acceleration force on the top line, and the corner- ing force on the bottom line. The large number shows the combined G-Forces, and the arrow shows the approximate direction of those forces. The combined G-Force is not the simple addition of the two forces; instead it is the “vector sum” of those forces, as shown in the example below. When the combined G-Force is under .15G, the arrow is displayed as an outline pointing straight ahead. The car is accelerating at .43 G. The car is braking at .32 G. The car is cornering to the left at 1.03 G. The car is accelerating at .45 G, and cornering to the left at .72G. The combined G-Force is .85G. 11 10 The car is accelerating at .45 G. The car is braking at .22 G. The car is cornering to the left at .43 G. The car is cornering to the right at .72 G. The car is accelerating at .45 G, and cornering to the right at .72G. G-METER OPTION 1: BAR GRAPHS Press and release the G-METER button as necessary to select “G-METER OPTION 1.” This display shows straightforward bar graphs of G-Forces. The top line shows acceleration and braking forces; the bottom line shows cornering forces. The default scale for the Bar Graphs is .80 G full scale. You can adjust this using the Setup mode. Typical Cornering G-Forces Below we list typical maximum cornering forces for different types of cars. Of course, auto testers use smooth, level pavement under optimum con- ditions to achieve these figures. Standard sedan .70 G to .80 G Sports sedan .80 G to .90 G For example, BMW M3, Acura RSX, etc. High performance .90G to 1.00G For example, Corvette, Viper, Porsche 911 Modified car 1.00 G or more ! ! .72G Cornering .45G Acceleration .85G Combined !

Press and release the G-METER button as necessary to select “G-METER OPTION 4.” The top line shows acceleration and braking forces, the same as G-METER Option 1: Bar Graphs. The second line shows your “Top 10” best 0 to 60mph times to date. (Of course, you must perform timed runs before times will appear in this display). The display continuously scrolls through your best 0 to 60 times. G-METER OPTION 5: BEST 0 TO 60 RUNS Press and release the G-METER button as necessary to select “G-METER OPTION 5.” This display does not show G-Forces, it only displays your 10 best 0 to 60 times to date. The display con- tinuously scrolls through your best 0 to 60 runs. Showing acceleration of .45G, and a second-best top 0 to 60 run to date of 5.60 seconds. Showing braking of .23G, and a third-best 0 to 60 run to date of 5.93 seconds. Showing acceleration of .22G, and a #1 top 0 to 60 run to date of 5.46 seconds. G-METER OPTION 6: BEST 1/4 MILE RUNS Press and release the G-METER button as necessary to select “G-METER OPTION 6.” This display does not show G-Forces, it only displays your 10 best 1/4 Mile times to date. The display con- tinuously scrolls through your best 1/4 Mile runs. Showing a #1 best 0 to 60 run of 5.64 seconds. Showing a #1 best 1/4 mile run of 13.26 seconds at 106.3 mph. 13 12 G-METER OPTION 3: PEAK HOLD Press and release the G-METER button as necessary to select “G-METER OPTION 3.” This display shows the peaks in acceleration, braking, left cornering, and right cornering G-Forces, and “holds” those numbers on the screen for 4 seconds. You can adjust the hold time using the Setup mode. Showing a recent braking peak of .48G. Showing a recent right cornering peak of .83G. Showing a recent left cornering peak of .57G. Showing recent peaks in all four directions. Showing a recent acceleration peak of .38G.

Press and release the G-METER button as necessary to select “G-METER OPTION 7.” This display shows only the combined vector forces (see the explanation in G-METER option 2: Friction Circle). In addition to a large numerical readout of the com- bined G-Force and an arrow showing the approximate direction of the forces, the RaceMonitor display also has a 6-segment bar graph meter so you can see your G-Force at a glance. Each segment of the bar graph represents .10G. The standard Bar Graph maximum is .80G, however you can change the maximum in the Setup mode. The car is accelerating and turning left with a combined G-Force of .25G. The car is braking at .55 G. Since the default Meter Maximum is .80G, the six segments indicate .30, .40, .50, .60, .70, .80G In this example, the Meter maximum has been changed to 1.30G in the Setup mode. In this case, the segments indicate .80, .90, 1.00, 1.10, 1.20, 1.30G The car is cornering left at 1.25G. G-METER OPTION 8: RACEMONITOR .05 Press and release the G-METER button as necessary to select “G-METER OPTION 8.” This display is the same as the RaceMonitor .10, ex- cept each bar graph segment represents .05G. In addition to a large numerical readout of the com- bined G-Force and an arrow showing the approximate direction of the forces, the RaceMonitor display also has a 6-segment bar graph meter so you can see your G-Force at a glance. Each segment of the bar graph represents .05G. The standard Bar Graph maximum is .80G, however you can change the maximum in the Setup mode. The car is accelerating and turning left with a combined G-Force of .25G. The car is braking at .65 G. Since the default Meter Maximum is .80G, the six segments indicate .55, .60, .65, .70, .75, .80G In this example, the Meter maximum has been changed to 1.10G in the Setup mode. In this case, the segments indicate .85, .90, .95, 1.00, 1.05, 1.10G The car is cornering left at 1.05G. 15 14

More Run Info ! ! Timed Runs Your Performance Computer’s intuitive “one-button” operation makes timing your car’s performance easy. You start the process by pressing the TIMED RUN but- ton. The unit performs an internal calibration, then the timer starts automatically when you accelerate, and stops automatically at the end of your run. It is not necessary to accelerate to a very high speed or for a full 1/4 mile to perform a timed run. The Performance Computer records data for short runs also (you must accelerate to at least 30mph). Detailed run results for your 10 most recent runs are automatically kept in memory. Review the results any- time with the UP and DOWN buttons. Tip for accurate timed runs The road does not have to be perfectly level, but it should be flat. In other words, testing on a slight in- cline is acceptable, provided the slope is relatively con- sistent for the entire length of the run. Of course, your car will accelerate slower on an incline. Temperature and wind will also affect your results. 1: HOW TO START A TIMED RUN 1 Car must be stopped. 2 Press and release the TIMED RUN button. 3 Wait a few seconds until you see: 4 Start whenever you are ready. NOTE: You do not have to press the CALIBRATE button before a timed run. The Performance Computer per- forms an internal calibration each time you start a timed run. (The calibration of the G-Meter function is not changed during a timed run, so the G-Meter will operate the same before and after a timed run.) Run #1 READY Start Anytime 3: REVIEWING RESULTS After the run ends, the unit will display two alternat- ing screens: This screen explains that you can see more informa- tion by pressing the UP and DOWN buttons. (See the following pages of this manual for details.) This screen shows one data point for your timed run, depending on the details of your run: 1 If your top speed was under 60 mph: It will show the highest “even-10mph” speed you reach. For example, if your top speed was 46mph, it will display your 0 to 40 time. 2 If your top speed was over 60 mph, but you decelerated before 1/4 mile: It will show your 0 to 60 time. 3 If you complete the 1/4 mile: It will show your 1/4 mile time and speed. 2: TIMER STOPS AUTOMATICALLY The Performance Computer automatically records all run data, and will continue taking data until any of the following occurs: 1 You stop accelerating. —or— 2 You travel 1/4 mile. —or— 3 Time exceeds 30 seconds. —or— 4 You press the Timed Run button again. Run #1 Complete O-6O 5.84 sec 17 16

The Performance Computer automatically records all run data during a timed run. To review the data after the run, press the UP and DOWN buttons. The data for your 10 most recent runs is automatically kept in memory. You can review the data immediately after your run, or anytime later. The memory is main- tained even when the unit is powered off. As you press the DOWN button, you’ll see the data for your most recent run first. Keep scrolling down for data from previous runs. The Performance Computer automatically numbers the runs, and displays the run number during timing. The system assigns numbers in sequence, and after you complete 99 runs, the counter restarts at Run #1. After reviewing the data, press the G-METER button to return to G-Meter mode, or press the TIMED RUN button to start another timed run. AN EXAMPLE OF RUN DATA Here is an example of the data you can view after each timed run. Each time you press the DOWN button, you will see another screen of data.

your car’s horsepower, you must enter information about your vehicle’s weight, drivetrain loss, and aero- dynamic qualities. Note: This setup is optional, and is NOT necessary for accurate Timed Runs or G-Meter function. In a timed run, the rated horsepower of your car’s engine is consumed in four primary ways: 1) The power to actually accelerate the weight of the car. 2) The power consumed by frictional losses in the car’s drivetrain. 3) The power used to overcome the rolling resistance of the tires. 4) The power used to overcome aerodynamic drag. With the Performance Timer’s Setup Mode, you can enter details about your car that will enable it to cal- culate the power used by each of these four items. The Performance Computer will then combine these fac- tors to calculate the approximate total horsepower being produced by your engine. To accurately measure engine horsepower, the following six setup items must be correct: Vehicle Weight • HP Min Speed • HP Max Speed HP Drivetrain Loss • Rolling Resistance • Drag CDA To enter Setup, hold the G-METER button. Then follow the on-screen instructions, which are: • To go to the next item, press the START button. • To change the setting of an item, press the UP or DOWN button. • To exit the Setup Mode, press the G-METER button. VEHICLE WEIGHT You must enter the weight of your vehicle using the Setup Mode. This information is usually available in your vehicle owner’s manual or brochure. Several different terms are used by manufactur- ers. “Curb Weight” is the weight of the vehicle without passengers and cargo. “Payload” is the maximum al- lowable weight of passengers and cargo. “GVWR” is the sum of the Curb Weight and the Payload, so it is the maximum allowable weight of the vehicle includ- ing passengers and cargo. You should use the Curb Weight if available, but add the weight of the driver, passengers and cargo, plus any additional equipment added to the vehicle. HORSEPOWER SPEED MIN AND MAX You must select the speed range for horsepower calcu- lations. The Performance Computer will calculate the average horsepower over this range, as well as the peak horsepower within the range. It is usually most helpful to choose a speed range and stay with that speed range. This makes it easier to see improvements as you modify your car, etc. The Setup Item “HP Min Speed” sets the speed that the unit starts measuring horsepower. The Setup Item “HP Max Speed” sets the speed that the unit stops measuring horsepower. The default speed range is 30 to 60 mph. DRIVETRAIN LOSS A surprisingly large portion of your engine’s horsepower is consumed by frictional losses in the car’s transmis- sion and driveline. Use the following table as a guide. 2 wheel drive with manual transmission .15 2 wheel drive with automatic transmission .20 4 wheel drive with manual transmission .20 4 wheel drive with automatic transmission .25 Note: If you prefer to measure wheel horsepower, change this setting to zero. ROLLING RESISTANCE This is a characteristic of the vehicle’s tires. For most passenger vehicles, the default of .013 is the proper choice. AERODYNAMIC DRAG CDA This setting is very important for accurate horsepower calculation, especially at higher speeds. In fact, the power needed to push your car through the air increases with the cube of the car’s speed. For example, if the aerodynamic resistance of your car consumes 10 HP at 30 mph, if you increase your speed by a factor of 2 (to 60 mph), the horsepower con- sumed increases by a factor of 23, or 8 times, to 80 HP. The CDA factor is actually the product of two items. “CD“ means “drag coefficient,” and it is a direct indication of how “slippery” the shape is—how easily it goes through the air. CD is the measure of the quali- ties of the shape itself, not the size. In other words, the CD of a small model of a Porsche 911 is exactly the same as the CD of a full-size 911. “A” is the frontal area of the car, in square feet. The product of these two terms, “CD“ times “A,” is “CDA,” and that’s the number you need to enter in the Performance Computer’s Setup Mode.

There are three possible ways to determine the CDA of your car: • Find specifications for your car’s CDA • Estimate your car’s CDA • Calculate your car’s CDA using a coastdown test Details on each method follow. 1 Manufacturer’s specifications or other research Very rarely do manufacturers list the aerodynamic qualities of their cars, unless those qualities of the car are exceptional. However, sometimes you get lucky. One of our test vehicles was an Audi S4. Searching on Google, we quickly found specifications for the faster European RS4, which is virtually identical in size and shape to the S4. Note: If you find specifications for foreign cars they usually list frontal area in M2, or square meters. Multiply those figures by 10.76 to convert to square feet. Try searching for the terms “drag coefficient” or “frontal area” and the make of your car. Also, we will be compiling a list of different ve- hicles and their CDA values and we will post that infor- mation on our website, so be sure to check that as well. 23 22 2 Estimate your vehicle’s CDA Use the following examples to estimate the CDA for your vehicle. Honda Insight .25 CD x 20.4 sq. ft. = 5.1 CDA Corvette C5 .29 CD x 21.3 sq. ft. = 6.2 CDA Porsche 911 .32 CD x 19.4 sq. ft. = 6.2 CDA Audi S4 .31 CD x 21.9 sq. ft. = 6.8 CDA Honda Civic .34 CD x 21.0 sq. ft. = 7.1 CDA Minivan or SUV .40 CD x 30.0 sq. ft. = 12.0 CDA Pickup or van .45 CD x 35.0 sq. ft. = 15.8 CDA Modern passenger car CD’s are usually .30 to .35. Van, SUV and truck CDs are usually .35 to .45. 3 Calculate your vehicle’s CDA You can determine the correct CDA number by using a “coastdown” test. • On a flat road, on a day with no wind, accelerate to slightly above 60 mph. • Put your car in neutral (whether your car has an automatic or manual transmission, it is important to put the car in neutral). • Measure the time it takes your car to decelerate from exactly 60 mph to exactly 50 mph. • Perform this test at least three times in each direction, to make sure your results are relatively consistent. • Average your times, then use the table to the right to determine the CDA factor. • Multiply your car’s weight times the CDA factor from the table to determine your car’s CDA. EXAMPLE: Find the CDA of a 4000 pound car that takes 17 seconds on average to coast from 60 to 50 mph. Look at the table. For 17 seconds, the factor is .001824. Multiply that times 4000 pounds to get the car’s CDA. 4000 x .001824 = 7.296 7.296 is the car’s approximate CDA. Multiply your car’s weight by this number to calculate your CDA. 10.0 .004305 10.5 .004018 11.0 .003757 11.5 .003519 12.0 .003301 12.5 .003100 13.0 .002915 13.5 .002743 14.0 .002584 14.5 .002435 15.0 .002297 15.5 .002167 16.0 .002046 16.5 .001932 17.0 .001824 17.5 .001723 18.0 .001627 18.5 .001537 19.0 .001451 19.5 .001370 20.0 .001293 The average time it takes your car to coast from 60 mph to 50 mph (in seconds)

Default is 3.0 For cars with very stiff suspension, change to 2.5 For race cars, change to 1.5 4 CLEAR SAVED RUNS Most users won’t need to use this command. The Performance Computer’s internal memory saves full details on the 10 most recent timed runs. The de- tails on these runs are always viewable by pressing the UP and DOWN buttons (and can also be downloaded to your PC or Palm with the optional software and cable). As you make additional runs, the oldest run is always automatically deleted from memory (to make room for the new run). However, if for some reason you want to erase the ten runs stored in memory, this menu item lets you do that. 5 CLEAR BEST RUNS Most users won’t need to use this command. The Performance Computer remembers the “Top 10” 0 to 60 and 1/4 Mile times from all the runs you have ever timed. (This memory is separate from the 10-run memory that keeps full details on your ten most re- cent runs. ) The “Top 10” memory only saves the ac- tual 0 to 60 times, and 1/4 mile times and speeds. This menu item lets you erase those figures. 6,7 HP MIN SPEED AND HP MAX SPEED These two Setup items let you choose what range of speed should be used to calculate your car’s horsepower. The default settings are 30mph for the HP minimum speed, and 60 mph for the HP maximum speed. 8 HP DRIVETRAIN LOSS This is a correction factor you can set to adjust horse- power calculations for drivetrain losses. Default is .15 (15% drivetrain loss). See the “Measuring Horsepower” section for more details. 9 HP ROLLING RESISTANCE This is a correction factor you can set to adjust horse- power calculations for rolling resistance. See the “Mea- suring Horsepower” section for more details. 10 HP AERODYNAMIC CDA This is a correction factor you can set to adjust horse- power calculations for the aerodynamic drag of your car. See the “Measuring Horsepower” section for more details. 11 METER MAXIMUM Most users won’t need to adjust this setting. This sets full scale for the Bar Graphs used in the G-Meter displays. The default is .80G. Race cars and very high-performance street cars can corner at 1.00G or more, so drivers of those cars may want to adjust the meter maximum. DETAILS ON SETUP MODE ITEMS To enter the Setup Mode, hold the G-METER button. Then follow the on-screen instructions, which are: • To go to the next item, press the START button. • To change the setting of an item, press the UP or DOWN button. • To exit the Setup Mode, press the G-METER button. 1 CAR WEIGHT You must enter your car’s weight for accurate horse- power calculations. Default is 2000 pounds. 2 PITCH CHARACTERISTICS OF CAR Most users won’t need to adjust this setting. This describes the specific way your car tilts back dur- ing acceleration. Default is 2.0 degrees per G. Cars with very stiff or very soft suspensions may need to change this setting for more accurate timed runs. For cars with very soft suspension, change to 2.5 For cars with very stiff suspension, change to 1.5 For very stiffly-sprung race cars, change to 1.0 (Settings we used: Porsche Turbo Cup race car: 1.3, Z06 Corvette: 1.5, Audi S4: 2.0, and Volvo sedan: 2.5) 3 ROLL CHARACTERISTICS OF CAR Most users won’t need to adjust this setting. This describes the specific way your car leans during cornering. Default is 3.0 degrees per G, typical for most performance cars. Cars with very stiff or very soft sus- 12 PEAK HOLD Most users won’t need to adjust this setting. This sets the time that peak values are held on the “Peak Hold” G-Meter display. Default is 4 Seconds. 13 SOUND Most users won’t need to adjust this setting. This turns the beep tones on and off. Default is On. 14 SHOW RUN DATA Most users won’t need to adjust this setting. This lets you choose what information to display after a timed run. The default is to display All Run informa- tion. You can also choose to display only some of the run data, as shown below. Choose “1/4 mile” data to show only: 1/4 mile time and trap speed 1000 foot time 1/8 mile (660 foot) time and trap speed 330 foot time 60 foot time Choose “Speeds” data to show only: Maximum speed Peak and average horsepower Time-to-speed data (0 to 10, 0 to 20, 0 to 30, etc.)

15 END TIMED RUN Most users won’t need to adjust this setting. You can choose to end timed runs automatically, or time each run for 30 seconds. Default is Automatic. END RUN AUTO When set for Automatic, the Performance Computer will automatically end timed runs when any of the fol- lowing occur: You stop accelerating. —or— You travel 1/4 mile. —or— Time exceeds 30 seconds. END RUN 30 SEC If you are performing very high speed testing, such as 0 to 120 times, your runs may continue beyond 1/4 mile. If so, change the setting to “30 sec.” Then the Performance Computer will take run data for a full 30 seconds each run. (To end a run any time before 30 seconds, just press the TIMED RUN button.) 16 BRAKE TEST You must change this setting if you want your Performance Computer to perform brake tests. You can choose to include “60mph to zero” brake test- ing in timed runs. Default is Brake Test Off. To perform 60 to 0 brake tests, change this setting to “Brake Test Auto.” TO PERFORM A BRAKE TEST (After you have changed this setting to BrakeTest Auto) • The car must be stopped. • Press the TIMED RUN button. • Wait until the display says “RUN READY” • Accelerate somewhat quickly to at least 63 mph (but no faster than 80 mph). • Immediately perform your brake test. Brake hard until your car comes to a complete stop. • After the car stops, use the UP and DOWN buttons to review your run data. (The brake test results will be included as additional items added to the standard acceleration run data.) 29 17 SPEED ROLLOUT 18 1/4 MILE ROLLOUT Most users won’t need to adjust these settings. You can select the criteria to start timed runs, both for speed measurements (0 to 60, etc.) and for distance measurements (1/4 mile, etc.), to match timing meth- ods used by drag strips and professional testers. Both rollout settings are adjustable from 0 to 25 inches. As you may be aware, in drag racing the timer doesn’t start the instant the car begins to move. An optical sensor shines across each lane, and before the race can begin, each driver must “stage” his car by moving it forward until the front tire blocks the beam. When the beam is blocked, the “Staging” light is illu- minated on the starting tree to show that the driver is in position. The ET timer doesn’t start until the front tire rolls forward out of the beam. The driver has a small amount of flexibility in where he positions his car before the start. The distance the car can move before triggering the timer is called “rollout.” You can set your performance timer to work the same way. If you choose no rollout, the timer starts the instant the car begins to accelerate. Or you can adjust the rollout distances to mimic the timers at drag strips, typically 8 to 16 inches for street vehicles. Your Performance Computer has two separate Setup items for rollout: “Speed Rollout” affects only the results for 0 to 10, 0 to 20, 0 to 30, etc. “1/4m Rollout” affects only the 60 foot, 330 foot, 1/8 mile, 100 foot, and 1/4 mile times. BUT DOES ROLLOUT REALLY MATTER? YES! It doesn’t seem like a few inches could significantly affect your results, but in fact, this small distance makes a big change in your car’s times. Even a very fast car is moving very slowly right after it starts a run, so depending on which rollout option you choose, you can affect your timed runs by 1/4 second or more. For example, if your car acceler- ates at .50G when you start your run, it will take .35 seconds to travel 12 inches. In this case, setting the rollout to 12 inches would result in times that are .35 seconds faster, since the timer won’t start counting until after the car travels 12 inches. Some car magazine testers and auto manu- facturers use rollout in their instrumented acceleration testing (including 0 to 60 times) to closer match drag strip starts. Their reported times are therefore always noticeably quicker than times reported by other testers that do not use rollout (and instead time cars from the instant they begin to move). The defaults for both the Speed Rollout and the 1/4 Mile Rollout are 12 inches.

19 TRIGGER Most users won’t need to adjust this setting. This sets the G-Force criteria to start timed runs. The default is .10 G, meaning that the timer starts count- ing when it detects acceleration of .10G. Lower set- tings may cause false triggering due to vibration of the car. If your car has significant vibration from the engine, you may need to increase the trigger criteria to eliminate false triggering of the timer. 20 CLEAR USER CALIBRATION Most users won’t need to use this command. This can be used to confirm the unit’s accuracy. 1 In the Setup Mode: • Change the Pitch to 0.0 • Change the Roll to 0.0 • Clear the User Calibration 2 Go to G-Meter mode, Friction Circle display 3 DO NOT PRESS THE CALIBRATE BUTTON 4 Hold the Performance Computer level with the display facing up. The unit should read very close to 1.00G 5 Hold the Performance Computer with its right side down and left side facing up. The unit should read very close to 1.00G. 6 Then for normal operation, use the Setup Mode to reset Pitch to 2.0 and Roll to 3.0 21 DATALOGGER Most users won’t need to adjust this setting. You can enable a special mode that allows saving a single 5 minute log of acceleration in memory, for download to your computer or Palm (you’ll need the optional software and cable). Here’s how it works. 1 Change this Setup item to “DataLogger On” 2 You can still perform conventional timed runs (by pressing and releasing the TIMED RUN button). 3 To perform a 5 minute Datalogger run, press and hold the TIMED RUN button on the Performance Computer. 4 Do not release the button until the display says “Release button.” 5 Perform your run. The Datalogger will take data for 5 minutes, or until you end the run by press- ing the TIMED RUN button again. 6 Download your data to your computer or Palm. NOTE: When you press the button to begin a Datalogger run, the 10 standard timed runs in memory are de- leted (to make room for the 5 minute run). 22 FACTORY DEFAULT Most users won’t need to use this command. This lets you restore all of the Setup items to their origi- nal factory default settings. It also clears all runs in the “10 Most recent run” memory, and the “Top 10 best times” memory. Optional accessories These accessories are included with some models, but are also available separately. DOWNLOAD SOFTWARE AND CABLE You can download detailed data of your runs to your laptop, PC, or Palm for analysis and graphing. See com- plete information provided with the software. PERMANENT MOUNTING BRACKET Some race sanctioning organizations may require that your Performance Computer is permanently attached to your car. This bracket replaces the windshield mount. USE CARE WHEN INSTALLING THIS BRACKET! (See our website if you’d like more details) 1 To remove the windshield bracket, carefully un- screw the large Phillips-head fastener and remove. 2 Carefully remove the long bolt. Take care not to lose the neoprene O-rings mounted on both sides in between the bracket and the housing. 3 Insert the bolt through the square hole on the new bracket, and carefully guide the bolt into the hole on the right side of the Performance Computer. BE PATIENT WHILE GUIDING THIS BOLT INTO PLACE. IT IS POSSIBLE TO DAMAGE THE CIRCUITRY IF YOU FORCE THE BOLT INTO POSITION. 4 Carefully line up the bracket, making sure the O- rings are in position. Bend the bracket slightly if nec- essary. Then carefully insert the Phillips-head fastener, and tighten. Do not overtighten. DIRECT-WIRE REMOTE CONTROL CORD IMPORTANT: This must be installed by someone expe- rienced with automotive electrical systems. If in doubt, see your car dealer or a car stereo installer. The black ground wire is fitted with a lug that must be attached to an electrical ground. The red-striped wire for +12 volts is fitted with an insulated 1/4” male spade lug connector. We have also supplied a special blue connector that allows you to tap into an existing wire in your vehicle. This connector can only be used with wire gauges 14 though 18. Most users tap into a “switched” circuit of the vehicle (one which is on when the car is on, and off when the car is off). To install the blue connector, position it around the wire you wish to tap into, then squeeze it with pliers until the halves snap together. Then plug the insulated connector from the power cord into this connector.

The G-Meter measures G-Forces in the plane of the road. After you calibrate it on level ground, it will read zero G’s on level ground. But on a hill, slope, or a crowned road, it will show a small G-Force reading. This reading shows the force your tires are exerting to stop your car from sliding down the hill. TIMED RUN ACCURACY For most cars, the Performance Computer will provide very accurate timed runs without changing any of the Setup mode items. However, to fine-tune your results to match times from a drag strip, you may need to adjust the Rollout and Pitch settings in the Setup mode. • Important: Do not adjust any settings based on the results of only one or two runs. Make at least three or four runs, and compare official track times to the times from your Performance Computer. Also, it is very important to stage your car exactly the same for each run at the drag strip, since changes in your position of only a few inches will significantly affect the drag strip times due to rollout. • The two Setup mode items that affect Timed Run accuracy are “Rollout distance” and “Pitch Character- istics” (the way your car tilts back under acceleration). Significantly modified cars may require additional ex- perimentation to determine the proper settings, but the following is a straightforward process to optimize the settings for most streetable vehicles. 1 Fine-tune “Rollout” in Setup Mode Adjusting the Rollout setting will change all of your times equally (60‘, 330’, 1/8 mile, 1000’, and 1/4 mile). Ideally you should adjust the Rollout setting so on average the Performance Computer’s 60 foot times are very close to the drag strip’s 60 foot times. Every situation and vehicle is different, but here are some ballpark adjustments: • Increasing the Rollout setting by 3” in the Setup mode will reduce the Performance Computer’s times by approximately .04 seconds. • Decreasing the Rollout setting by 3” in the Setup mode will increase the Performance Computer’s times by approximately .04 seconds. 2 Fine-tune “Pitch” in the Setup Mode After you’ve adjusted the Rollout setting so the 60 foot times are as close as possible on average, you can ad- just the Pitch setting to correct for your vehicle’s exact suspension characteristics. Changing this setting will not significantly affect 60 foot times, but will affect 1/8 and 1/4 mile times. If the Performance Timer shows times that are faster (shorter times) than the official drag strip time, you should increase the Pitch setting. If the Performance Timer shows times that are slower (longer times) than the official drag strip time, you should reduce the Pitch setting. Every situation and vehicle is different, but here are some ballpark adjustments: • Increasing the Pitch setting from 2.0 to 2.2 will increase your 1/4 mile time by approx .03 sec. • Decreasing the Pitch setting from 2.0 to 1.8 will decrease your 1/4 mile time by approx .03 sec. Here are some pitch settings that provided very accu- rate results with some cars used in our testing: Porsche 944 Turbo Cup race car 1.3 Z06 Corvette 1.5 Audi S4 2.0 Volvo and Ford sedans 2.5 Be sure to write down your settings when you person- alize menu items for your vehicle, in case you need to reenter those settings in the future. RELOADING FACTORY DEFAULTS In the unlikely event your Performance Computer ever shows gibberish on its display or does not respond nor- mally when you press the buttons, follow these steps to automatically restore the factory software. NOTE: This procedure also returns all of the Setup Mode items to their factory default settings. You will have to reenter information about your vehicle’s weight, etc. TO RESTORE THE FACTORY SOFTWARE TO DEFAULT: • With the Performance Computer unplugged, press and hold these three buttons: UP, DOWN, G-METER. • Plug the unit in while you continue to hold down the three buttons. • The display will read “Loading factory defaults.” • Release the buttons. • Using the Setup Mode, adjust items to your per- sonalized settings (vehicle weight, etc.). DEMO MODE There is a “demo mode” that can be used to show the basic capabilities of the Performance Computer. Hold the UP button and the G-METER button for five sec- onds to activate the demo mode. To exit this mode you must power down the unit and then turn it back on.
