A carbed V8 ECM work for a fuel injected turbo V6? Absolutely not. :nono: The injector drivers are in the ECM.

The part numbers for the turbo V6 ECMs are around the site. The 86-87 ECM is actually shared with a few FWD V6 Buicks of the era and easier to get, but not much easier as all the cars age.

Thanks! i found a 87 g/n Ecm that i think will work. I purchased a 87 3.8 turbo drivetrain that I am tryn to make work. The 3.8 has the wiring harness, but the harness has been damaged around the connectors that go to the ECM. If possible, do you think i can splice into my old harness to repair my new set up? Any help would be greatly appreciated!

Probably not ... there's some pretty significant differences in some of the interconnects. Best bet is a new harness ... Casper's sells them and I've seen some in the FOR SALE section occasionally. Usually around $300-500 but sometimes a smoking deal pops up.

Kind of depends on where the harness was hacked up...
