). Now I'm thinking of changing over my '87 Audi 5000 Turbo Quattro which has been running for 3 years on a v2.2 board and 2 years on DT1.02 code. I think there may be some hangups though.First off is ignition triggering. The stock ECU which is still running the ignition (very well I might add) uses 3 main sensors to determine timing. There are 2 VR sensors at the flywheel, one is triggered by a pin at TDC, the other counts flywheel teeth to determine RPM, then also a hall sensor with a single window in the dizzy. The system uses the hall sensor only during cranking to figure out which hit of the TDC VR sensor is combustion stroke, then once this is determined the hall sensor is no longer used and the ignition events are calculated based on the RPM sensor and TDC.
From my understanding of current MSnS-E software I can not use any of the above to trigger off of, correct? Could a firmware change fix this?
The non-turbo cars used a vacuum advance hall sensor dizzy with 5 windows to run the ignition, and I do have one of these dizzys laying arround, but I don't want to go that route due to innacuracy.
Second question is about knock sensing. Has anybody out there used a knock sensor from an 80's VW/Audi car? I imagine they all work the same or close at least.
The one window hall sensor.
The 5 window hall sensor.
