I have a 91 dodge stealth that I'm using a Link v14 ECU with PC Link 2.5. I don't have a hand controller so I don't know if I'm missing any functionality that PC Link does not offer. While logging the car I have noticed that going from cruise to enrichment the O2 sensor picks up a ridiculous lean spike. The O2 goes from reading a relatively steady 0.4v-0.6v straight to 0.0v for about 0.2 seconds. Then it climbs back to where it needs to be, maybe a tad richer because of the enrichment. I've played around with the acceleration enrichment tables and the wake up pulse cycles but its still there. I'm using a MAP only set up and have the computer configured for the 3000gt to allow sequential injection. My closest lead is that I can slowly raise the RPM from idle, ~900RPM, to ~1300-1400RPM before the computer notices. Obviously if I do this slow enough with no load nothing phenomenal happens. My main question I have is, "Is the acceleration enrichment and wake up pulse tied in any way to TPS when I have my computer configured for MAP only and sequential injection?" I thought TPS was not required for any of the settings I currently am employing. I browsed the G1 forums, but I couldn't find a relevant solution. Your company offers amazing service, even on its legacy products. Really looking forward to hearing from you. Bleu
