I would like to order the ECU for our new project. Golf2 with swapped R32 engine from Touareg (engine code BMV). Harness, config and tuning of the engine is not a problem for me, but we need help with CAN communication with standalone DSG gearbox control unit from company HTG-Tuning.
I was talking with HTG and they say that they are able to implement all CAN protocol types to their GCU.
See AimCanBusMessages for CAN-ID and data-content:
GCU needs these data via CAN:
Let's start with most basic data:
A) from ECU to GCU:
- RPM
- PPS (or TPS if only mechanical throttle body is installed on engine)
- MAP
- Launch Control active
- actual calculated torque
- when no fuelcut, approximately proportional to MAP*(1-igncut)
- it's extra signal, GCU can be fully functional and performing without this value - it's controlled then by different method
B) from GCU to ECU:
- driven gear
- upshift request (to perform gear cut)
- downshift request (to perform blip)
- output speed
- trans temperature
Later we can extend this set with additional data like Slip % or other.
My questions are: Can i did this with ecu ordered with 2 serial ports and your AIM to CAN adapter? If i understand it right, CAN adapter must be programmed before purchasing. Can you please tell me if some of pdedefined dash CAN protocols (for BMW or Audi) can provide data which GCU needs? Or can you please make for us a new protocol for GCU? Or can you send me an existing CAN protocol documentation where HTG can find datas which they need?
Please help me if you can. It is possible to easy connect this GCU to Ecumaster ecus, but i really love Vems and want to use it for this car instead of ecumaster. Maybe this threat also will help another customers which wants to use Vems with DSG gearboxes. HTG-Tuning are really friendly and innovative company which looks like someone who wants to make a new cooperations. Since dsg geafboxes are very popular now, i think here is the chance to open new markets and find new customers for Vems ecus.
