Already replaced stock Bosch Motronic M2.10.3 with VEMS 3.6. Stock wiring is used for installation, so I had to use Motronic 55 pin connector and VEMS GenBoard. Also some very small adjustments to stock wiring were applied for MAP sensor instead of MAF.
Items used:
- Vems GenBoard v3.6
- Alubos case with motronic55 frontplate
- 8 x Ignition driver
- 10 x Injector or WBO2 heater driver
- Idle stepper motor driver
- Wideband connector
- Dual channel knock sensor interface
- EGT amplifier chip
Additionally were bought:
- Wideband sensor
- Cheapest external MAP sensor I've found from Reanult Logan.
Wiring diagram for GenBoard and Motronic connector:
There are two changes in original wiring here:
- MAF connector is cut and replaced with 3 wire MAP connector
- Narrow-band lambda probe has been replaced with wide-band sensor. 3 wires are attached to unused pins on Motronic connector , 2 power wires for heater connected to original lambda connector
