Thanks for the positive review Spencer! The fiddling with initial tune was my fault: the tune for NA came from a car that had different injector output enabled for injectors 3+4 and obviously it did not work for Spencer's car. After I changed that in the file, he uploaded it and car ran like it should.

I offer Plug and Play VEMS units for many Porsches. So far I have made kits for 944 NA, 944 Turbo, 944 S, 944 S2, 968, 911 3.2, 964, 993 (both normal and VRAM engines). Also many non-Porsche models.
I build the VEMS ECU from parts I buy directly from factory and fabricate the adapter harness (or configure VEMS with Motronic connector if customer wishes so).

Note that it is one of the very few ECU's that can easily utilise factory speed and ref sensors, no need to fabricate a trigger wheel or something.

Note that you can also use the VEMS unit on some other car as well, only need a harness adapter for that. It supports two complete configs in the ECU, not just table switching.
