Can a 7427 ECM be used on a boosted 4cyl Dohc?

I read somewhere the 1990 707 ECM on a 2.3 Dohc quad-4 grand am would not support the stuff you need for boost. I found a couple ecm numbers here like 1227749. I have several 427 ecm's so wondered if I could use one of the 427's instead of the 749?

The 16197427 doesn't natively support boost. There are a few people who have successfully used one in a boosted environment. See http://www.gearhead-efi.com/Fuel-Inj...th-turbo-boost
He has several threads on here dealing with his project

Ok thanks

I thought I read someone putting a turbo on a blazer :-).....from all the stuff I read on here I have no doubt anything is possible and seen the 4cyl option on 427, wasn't sure if Dohc made any difference tho but I posted before I remembered reading a 1228321 wouldn't work with a 2.5l with a distributor because the ignition type difference, distributor vs coil pack. The engine I'm using has a cdi and as far as I can remember 427 stuff is all distributor. So I'm assuming the two won't work together. Or I'm I wrong??

Maybe a better question....is there something to look for in a bin that says it may support boost or just find a super/turbo charged car ECM?

The '7427 PCM would not be a good choice for what you propose.

I can't find the info I want quickly, but $59 MIGHT drop into your current ECM and be a good choice.

Alternatively, a more common 1227730 ECM can be used with $58/$59 and would do what you want.

Are the 1227730's in the camero the same as in sunbird? I may have access to a camero 7730. I will look at $59 stuff, maybe make a chip and try in my 707 if there is a bin posted......

Yes, all '7730s are the same. If you do get it, I might be interested in the MEMCAL, depending on what the original engine application was.
