1988 Porsche 944 Turbo

Basic Info:

Current FW: 1.2.31

Selected drop down Primary trigger config for Porsche 944 Turbo, cranking RPM is ok - no trig errors when cranking.

Trigger errors when running engine.

Did you reverse the polarity of the reference sensor? It is needed with 944 Turbo. PeepPaadam? P.S. You did not buy the VEMS from me right? Is it wire-in or plug and play install?

  • I did not, was not aware this was necessary like on the 5 cyl audi's. I did not buy the VEMS from you, this customer car had a fire so stock harness was pulled out, new ECU and Twinshield harness was used here. Thanks you for the help! I will try with the modification and report back.
  • Update: Reversing polarity worked! Thanks!

Attached is the base config:
