Hello,
I'm from Germany and have the Vems 3.xx PNP in an Audi S2 ABY.
Unfortunately, I have a lot of problems with it and I hope the solution.
With the original ECU the car is running without problems.
When I Vems connected with the car, there is no ignition spark, and what I find so strange when you start in Mega Tune no RPM displayed wird.Also the pointer will not move!
The pin's peiden from donors for ignition timing G4 were exchanged!
Did perhaps someone such problems?
Here is the Config files.

I hope the files help you to recognize the errors
I now have the exhaust voltage test to the sparkplug for coil 1
When the ignition is on, it is 0.5 V.
If I start it 1,2-1,3 V
But that is still too little and can only lie at the Vems?
