I think so to. But for pet projects like this, I am cheap. So that means junkyard time. I need the pig tail to go with it to, so if i can get it all at once I will be quite happy.

Thanks for all the info and links!

You guys will want one of these. Useful for pulling pins in ECM connectors, weatherpacks etc.

^^^^^ those tools keep you from going nuts when re-pinning. Get one.

Also, found some info on the computer. Thought it may be useful, have fun!

The 1227165 with $12P code running a Fiero 2.5L - he started with the Truck 2.5L ECM

Mouser 50/box is much cheaper than NAPA

So I hafta wait 'till it gets here - then we'll be able to see what's going on.

I got the ALDL cable from RedDevilRiver yesterday - snail mail is SO slow (and STILL expensive)

At least we can now make some progress. TunerPro can now communicate with the ECM.
I ran the engine and saved a datalog file that I sent to Chet that he can have a look at to see what's happening.

I think we can sort things out and get this car running again by the weekend - I hope.

If your engine is mostly stock and runs fine - don't bother changing the ECM.

Fierosound, care to elaborate, or at least share your experiences?

Still working on it. The hardware is great, but I don't have the expertise to tune this thing.
I'm going to stumble around in TunerPro RT some more this weekend.

Even if I can get it driveable, I'll be taking it to Wester's.
