Summary of change:
Installed custom VEMS plug and play (55pin Motronic) to Porsche 964 Tiptronic, works fine but Tiptronic is in limp home mode due to the missing fuel injector pulsewidth signal. I connected the P259 pin 4 (ch0, with pullup) to the corresponding pin (pin 32 on Motronic 55pin connector) and configured boost gauge output hoping it will settle for just some kind of square wave signal but Tiptronic is still in limp mode. Any tips how to proceed with this? I think fuel injector load output signal would be useful for many cars, even Audis use this to calculate fuel consumption, many Porsches etc. With display you can just ignore it but with tiptronic it ruins the driving -> cannot be ignored...
