What's the story? Will it work?



Who has tried it????

I had an aftermarket M2 ecu for a 94 in my 93, a while back. I had no problems

Good to know. Thanks.

How 'bout you guys with stock ecu's?

I am pretty sure that it works fine. The onlything I think you have to watch is the cali ecu's because of emmisions. The maps are probably different but I can't say for sure. That is just speculation on my part.

The only difference is the 94's all came with a 93 Cal only style EGR valve. If your 93 is a Cal model or you've added a Cal EGR then you'll have no problems.



If you add a 94 ECU to a 93 49 state model you'll either get a "check engine" light or you'll have to add a EGR from a 93 Cal model or 94.

actually the 93 and 94 cali ecus are the same #, N3A3. the federal 94 is N3C1, but it works with the ca egr valve

mike your freaking amazing how you remember that stuff off the top of your head. your the man https://www.nopistons.com/forums/pub...#>/biggrin.png

Thanks...again.

Glad that you guys are out there helping us newbies.



Ooops..to confirm terminology for us Canadians....I have a 93 "non-Cali"...and if I put in a 94 non-Cali I will STILL get the check engine light correct?



To correct this problem I have read that I can "fool" the ecu. But how much would a used Cali egr run me? Or would it really be best to try and fool the ecu by following some of the instructions in the Lightening in world site?

Good for you!! You are bound and determined to learn to work on that car eh. Tom

yes. we haven't had sucess fooling the ecu, but maybe we did something wrong?
