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.
The man who says something is impossible, is usually interrupted by the man doing it.
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.
