How to check the ECU version
Connect to the ECU, open the Settings - Firmware tab
v2.4 / v2.5
New features:
- Integrated Bluetooth connection
- Permanent battery connection
| Power | |
|---|---|
| 12V | permanent 12V through fuse |
| IGN | ignition on signal |
| GND | ground |
| Outputs | Voltage | Current | |
|---|---|---|---|
| COILx | to ignition amplifiers | + 5V / GND | 20mA |
| INJx | nozzles | - | 4A |
| PWMx | powerful PWM outputs | - | 4A |
| M1, M2 | DBW motor | + 12V / GND | 6A |
| A, B, C, D | stepper motor / general purpose | + 12V / GND | 0.5A |
| X1, X2, L1, L2 | general purpose | - | 0.5A |
| H1, H2 | general purpose | + 12V | 0.5A |
| X3, X4 | general purpose or PWM outputs | - | 0.5A |
| TACH | tachometer | - | 0.5A |
| BUS | bus for display or logger | - | 0.5A |
| 5V | sensors power supply | +5V | 0.1A |
| Inputs | |
|---|---|
| DAD | MAP sensor |
| TPS | throttle position sensor |
| O2 | lambda sensor |
| CLT | coolant temperature sensor |
| IAT | intake air temperature sensor |
| K1-K8 | buttons input. K1-K4 activated by +12, K5-K8 activated by minus |
| AN1,2,3,4,8 | analog input without pull-up |
| AN5.6 | analog input with pull-up (2kΩ 5V). For temperature sensors |
| AN7 | input with a weak pull-up to 0.45V. For 2nd lambda sensor or analog input without pull-up |
| DH1,2,5 | hall sensors |
| VR1+-, DH3+-, DH4+- | VR sensors |
| VR2+-, DNO+ | VR sensor / camshaft sensor * |
[*] When connecting VR camshaft sensor, use inputs DNO+ and VR2-. When connecting VR ABS sensor or other sensor with a high pulse frequency - use the VR2+ VR2- inputs
[**] The main relay should only be connected to outputs X1-X4.

Differences:
- the power supply must be switched off together with the ignition
