Ignition (O), only for CDI version, ignition High Voltage output. It connects to the high voltage coil (ground ended). Engine temp (I), this input can be connected to a NTC temperature sensor (ground ended). Two 2K5pull-up resistors must be installed on the board. A compensation table exists in the FW to use this input. TPS, Throttle Position Sensor (I), this input (0 to 5 volt) is used for the TPS axis of the fuel map. Currently it is not used for the ignition. Injector (O), this is an open-drain output. It connects to ground the injector to be activated. Injector must be 12 volt ended. Warning: injector outputis not short-circuit protected. Pickup (I), this input must be connected to the pickup signal (ground ended). Minimum starting voltage is about 2 volt. Positive and negative pulses are acquired. Default order is: positive pulse at maximum advance (for example 40 BTDC), and negative pulse at minimum advance (for example 10 BTDC) +12 Volt (I), 12 volt from battery after main Switch. ECU is NOTreverse polarity protected. MAP (I), this 0-to-5-volt input is a provision. It is acquired and shown in the program but it is not used at all in the current FW version. Air temp (I), this input can be connected to a NTC temperature sensor (ground ended). Two 2K5 pull-up resistors must be installed on the board. A compensation table exists in the FW to use this input. Map/Table Selector (I), thisdigital (0/1) input is a provision. It is acquired and shown in the program but it is not used at all in the current FW version. It activates when connected to ground. Fuel Pump (O), this is an open-drain output. It connects to ground the fuel pump to be activated. Fuel Pump must be 12 volt ended. Warning: Fuel Pump output is not short-circuit protected. GND (I), battery ground. HV alternator (I/O) /TCI (O), in CDI version, this input is connected to High Volt alternator (200-300 volt). In TCI version, this output is the 12volt coil output, the coil must be 12-volt ended. RX (I), RS232 RX line. TX (O), RS232 TX line. Stop (I), this digital (0/1) input stops the engine when connected to ground. It disconnects all functions: injection, ignition and fuel pump.

16. Lambda, this 0 to 5 volt input is a provision. It is acquired and shown in the program but it is not used at all in the current FW version. 17. 5V TPS, 5 volt output for TPS sensor. It must not be used to power any other device. 18. GND, battery ground.

Channels
The checkbox at the left of eachchannel name enables or disables the visualization of the channel on the graph. The value at the right of the channel is the scale used to paint the graph. It can be changed to fit the signal on the graph. • RPM, engine rpm. By default it is used the positive pulse from the pickup, but it can be changed on the hardware. • IGN, current ignition advance (degrees or raw units) • IGN_DEL, currentignition delay in time from reference pulse • EFI, current injection value (degrees or raw units) • EFI_DEL, current ignition delay in time to the point when the injection starts • THR, throttle value: percentage after MIN and MAX calculation or raw value (0 to 255). • THRa, throttle acceleration. It is used for the fuel enrichment, if the option is enabled. • TEMP1, engine or air temperature (to bedefined). Used in compensations (if enabled) • TEMP2, engine or air temperature (to be defined). Used in compensations (if enabled) • LAMBDA, lambda reading (raw or AFR), used ONLY for monitoring • MAP, MAP sensor reading (raw or AFR), used ONLY for monitoring • Prescaler, it is an internal value, used for diagnostics • COMP, compensation from TEMP1 (if enabled) • COMP2, compensation from TEMP2...
