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,

Lyle



If the ECM I posted in the photo will work for you, shoot me a PM.

I replied to your PM, but not sure it worked.
Did you get it?

Daryl,
I looked in the PM area of the forum. It shows that you sent me a PM but there is no message displayed.

I think I sent you my email in one message. Please try that.

Lyle

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

You would need the 1227730 ECM and it's harness plugs, of course. Also the ECM tray from an 87 or 88 L4. A few new wires would need to be added to your engine harness while some can be removed, and that's easily done while the engine is out of the car. Sinister Performance can tune the 7730 ECM for your engine, transmission and tire setup. You would need to purchase the Digital EGR Adapter Kit from Georgia Fieros http://www.fiero.nl/forum/Forum4/HTML/057540.html to eliminate the troublesome electro/pneumatic EGR system you're currently stuck with. An oil pump drive from a later year 60* V6 would be needed to replace your distributor. The kit gives an extensive list of vehicles that use the Digital EGR Valve that mounts on the adapter plate.

This video may be of help, though it's for a 3.4 engine, rather than a 2.8 which doesn't have the crankshaft sensor and knock sensor ports. Those would need to be located differently on a 2.8.
