Stage 0
I thought I do the smallest first step possible:
Install a genboard to get sensor data only. First time (this stage) I want to see that all the necessary input data is OK.
These data are:
- VR signal -RPM (need to share with motronic)
- cam signal from ign wire -optional
- MAP (sensor installation needed)
- IAT (sensor installation needed)
- CLT (need to share with motronic! otherwise motronic will work even worse either at cold-startup or warmed engine)
- WBO2 (sensor installation needed).
If I can successfully get/share those signals, I can watch original working parameters and ready to go to stage 1.
Tell me if I'm wrong with this.
Buy list
- Wires and plugs -- got it (whole harness form junkyard)
- Fuses and housing -- got it (whole harness form junkyard)
- M18x1.5mm/thread nuts to weld into exhaust (for wbo2) -- got it
- MAP sensor (guess 2.5 bar is fine), some pressure hose and T-shape fork
- IAT sensor and some sort of mounting
- GenBoard himself :) and rescue kits or whatever I need to power up
