4A-GZE conversion

Some of this can be accomplished through the V8 Camaro and Corvette MAF systems but you're forced to do more work before you even start the engine because you have to change the calibration so it will work with a four cylinder engine.

I guess I should have asked this in the first post, did GM ever use a MAF based tune with a 4 banger? it sounds like you're saying I'd have to mod V8 Bin files to make it work.

Not here in the US, at least as far as I'm aware. The 7165 from early TPI Camaros and Vette's was also available in some four cylinder applications but those were SD.

LOL, ok, then it looks like we'll be working SD, I figured there was a MAF 4 banger code out there already tried and true.

plenty of 4age's running on 1227165 ecus on our forum the dizzy is pretty easy to interface with using a GM 7 pin hei module http://pcmhacking.net/forums/viewtop...lit=4age#p8830 team it up with the 2 or 3 bar aussie modified OSE $12P software and tune away fuel and spark tables to 9600 rpm and 30psi of boost

Thanks for the link. at this point, I was thinking about convincing my buddy to have a trigger wheel made so he can go DIS. wouldn't be too hard, and would be a big performance upgrade, but if the stock dizzy is interfaced easily enough, than all that would need to be adapted would be a TB with the proper IAC and TPS.

You can always start with the dizzy and then move to DIS later, like I did on my L28 in my Datsun years ago.

yeah, I could, but it's not my car, and me and my buddy are both military, and almost guaranteed to be in geographically different locations in 6-8 months. helping with software related stuff can be done over email. hardware would be a little more tricky.
