TECHNICAL DOCUMENTATION 01/04/2003 GAUGE Notes: MyChron 3 XG technical documentation, dimensions and pinout MyChron 3 XG Internal lateral accelerometer CH2 CH1 CH4 CH3 Power IN GEAR Beacon Speed RPM Figure 1: MyChron 3 XG Introduction MyChron 3 XG represents the new generation of Aim data acquisition systems for car racing. MyChron 3 XG monitors and displays RPM, 4 fully configurable analog inputs (pressure, temperature, potentiometers, Lambda sond and Pitot tube speed sensors), speed, current gear number, lateral G-force and lap (split) times. It also has a backlight, which can be switched on during night racing The logger records the following parameters: • 4 analog inputs: the user may choose the analog inputs among pressure sensors, temperature sensors (VDO, thermocouples, thermoresistances), potentiometers (linear and circular), Lambda sond and Pitot tube speed sensors; • engine’s RPM, sampled either from the ECU (square wave signal) or from the coil; • lap and split times; • engaged gear number: the gauge is able to sample the gear number either using an “on- board” gear sensor or calculating them using the speed vs. RPM ratio; • 1 speed input; • lateral G-force: the G-force sensor is mounted inside the “Junction box”; • logger temperature; Data is stored in a huge 2 Mbytes internal flash memory and may be downloaded to a PC through an USB cable. Please, refer to the following drawing to get further information concerning the gauge’s display.
