Please help.. 3100/3.1 question

[Chapstick]

So I have a simplified harness and tuned computer for a 3100 what does it take to make it work on the 3.1 motor? I derby the cars so not really concerned about how it looks or if I have to cut things up, trying to build a 93 lumina with the 3.1 my harness and computer is off of a 98. 3100 Monte Carlo. It’s the lmmf harness and computer I was told all I had to do was swap injector harness over for it to work.. anyone that could help would be greatly appreciated

your biggest issue, I think will be the lack of a cam position sensor on a 3.1 and potentially lack of secondary crank sensor (if the 3100 has that, I'm not sure). I'm sure you don't care about things like o2 sensors and the like so I'm trying to think of things that would prevent it from just working. is a 3100 a MAF car? if it is are you even running a maf? not that I think it would matter as you could just slap that in line on a 3.1. 

Transmission control might be a problem, but again not sure how much you care about that since you'd probably just be using first and reverse

Not sure how a 3100 PCM would cope with the lack of cam sensor signal, its possible that it would work.

Truth be told the stock engine harness in that car is pretty darn close to a stand alone system. I've also seen derby guys use modified 3.1 intake manifolds with a carb base welded on and a distributor out of a 3.1 U van if you really wanted to keep it simple
