Imp558 Posted July 28, 2016 Report Share Posted July 28, 2016 The biggest question is whether or not there is software out there to program that computer. Quote Link to comment Share on other sites More sharing options...

rich_e777 Posted July 29, 2016 Report Share Posted July 29, 2016 VATS is bypassed by splicing in a resistor matching your key on the ignition cylinder harness, not sure which without a 3100 diagram in front of me. Most locksmiths can do this for you. As far as doing things to the PCM its about impossible because reasons around a non removable memcal module. I am planning for a 3400 V6 swap in my 94 Cutlass sometime and in my research and parts gathering I was referred to the PCM out of an early 90`s 3.4 DOHC found in the Z34, GTP and some Cutlass models or similar years because you can remove the memcal and have it reprogrammed easier. I`d recommend you look into this swap as you can pretty much use your 3100 harness for the 3400 and this engine as a better aftermarket selection than a 3100 does. What sort of racing you doing?

heiner921 Posted July 29, 2016 Author Report Share Posted July 29, 2016 i got it figured out last night guys.... i used a ecu and its harness from an obd1 90 lumina 3.1L and the engine harness, swapped it to my 3100 and runs well ecu harness has about 25 wires and a few grounds and a few power wires. NO reprogramming was needed i shouldnt say i race theses cars, i destroy them in demo derbies... so of these engines i have made them carbed. kinda neat Quote Link to comment Share on other sites More sharing options...

Nas Escobar Posted August 5, 2016 Report Share Posted August 5, 2016 I think that may be considered suicide. I'd like to see Ford Taurus being used but I suppose they would be expected to run and move under their own power. Since learning that W body cars are popular in derbies I was wondering what else is popular. Turns out Cavaliers are too but there's also a couple of people derbying Camrys, which I approve 100%. Not so much Accords which I would like to see. Surprising they don't derby Nissans... or better said haven't seen one. Those things are built more solidly than the Toyotas and Hondas. Anyways, I mention it because what they do on the small cars is get bumpers from other cars that will make the cars "stronger". There's someone that was derbying a mid 90's Camry with a towncar bumper. Quote Link to comment Share on other sites More sharing options...
