Will the s4 ecu work with the s5 engine? If it will would I have to do anything to make it work? Or is there no hope to get it to work? Or just to big of a pain and just use the s5 ecu?

Thanks

 

So you understand what I'm trying to get at better. I'm trying to put my 91 gxl motor in my 88 se.

 

stupify, didn't I go over this with you before? If you swap out everything like I said on the engine, just use your stock series 4 ecu and you'll be all set.

 

I did this with a TII and it was fine.

It should work just fine for an n/a as well, just swap everything over like SonicRaT says.

You're going to want to do that anyway unless you have EVERYTHING off the S5 motor.
