ECM for 1987 2.8L (Page 1/2)
lyleap-gmc JUL 24, 04:55 PM
I'm in the process of replacing a locked up 4 cylinder with a 1987 2.8L V6. I need to replace the ECM to match the V6.
What ECMs can be used with this engine. It is stock.
It would be most helpful if the donor car is listed as well as the Service Number.

Thank you to all,

Lyle

The ECM is 1227170, but you will need to get the right PROM based on type of transmission and possibly tire size.

All 85-87 Fiero v6 ecms with the proper transmission prom will work. It doesn't have to be 87 specific.

I would like to have the make, model and year of a donor car. I know that any Fiero ECM from '85 to '88 will work.

There just aren't that many Fiero ECMs available. I know of one but he is keeping it in case he reverts his '87 back to stock.


I can do some programming of a suitable ECM if need be.

Thanks to all who reply,

You could convert it to a 1227730 ECM, do the digital EGR conversion and have a more responsive engine plus eliminate the troublesome Fiero EGR system.

Fierostore has them. Or ask in the MALL and somebody can sell you a used one.

We have quite a few V6 and L4 ECMs, even AC Delco factory rebuilt units in the box.

What is involved in the EGR conversion? Sounds like a great idea.

This is in my 86 GT 4 speed parts car. I drove the car into the garage, so it seems to work.

Yes, 1226869 is the only other ECM that was used on 6 cylinder Fieros. It was used for 1985 and apparently early 1986 cars, and will work in '87 and '88 cars.
