1227730

[ron768]

 When I pulled the ecm from the car at the strip yard, I didn't pay attention to what it was. So, is there a way to find out what car the 1227730 ecm came out of?

[Raydar]

There should be a 4 character broadcast code. AKYZ or something like that.
That will tell what it came from. If it's not printed on a label on the outside, it should be on the blue MEMCAL (chip carrier assembly) on the inside, under the small cover. It may be stamped on a silver label on the chip, visible through the hole in the blue cover.

The one I have here has a silver label on the inside, visible through the hole.
Says:
DELCO
AUXW
3817

It's also from a 7730.

With that said...
There is a small handful of programs that people start with, in order to run the Fiero. Which one depends upon whether you want to keep the distributor, or switch to DIS (coil packs.)
A new chip (or at least a new program) will likely be needed, anyway, so it's not terribly critical what it came out of.
You will need some sort of crank sensor to run DIS, I think. I think people  have added them to the harmonic damper.

f85gtron has already done this swap. He would be... "da man".

TopNotch also posted a thread with a video.

Ron,
Yours reads
DELCO
ADRA

It's from a 1987 2.8 auto. When I'm finished with it, It will be BAWX, which is the latest (1991) version of broad cast code for 60° v6 manual with dizzy that gm released.
The only thing you have to watch out for when grabbing the ecm From the junk yard is the memcal because of the knock sensor stuff in it. An 8cyl stays with 8 cyl and 6 with 6. Its said you're not supposed to mix and match......not sure why though.

Obviously Ron is way ahead of me...

Having said that...
If anyone stumbles across a V8 memcal, I have a V6 memcal that I will happily trade, or I'll buy it from you, outright.
If desired, I'll install a socket in the memcal before I send it to you, so that you can swap chips easily. (Depending upon your programming setup, you may not care about this.)
The best place to find a V8 memcal is a 90, 91 or 92 TPI 305 or 350 Camaro or Firebird. Kind of uncommon, these days.

Thanks guys. I remember looking a 4 car that day and getting parts off 2. With this list, I can narrow it down to the Celebrity . So, I will be ordering a knock sensor from rock auto today. Thanks again.

What does code BABM list.  I know I got it out of a Beretta and I believe it was a 3.1.  That tag is on both the body and the cover plate.

I thought I remembered you mentioning a Celebrity, but I didn't want to mislead you, in case I remembered incorrectly.

Got the knock sensor in today as well as the chip back from Ron. Waiting on a gasket for the EGR base to crossover pipe. Saturday and sunday are going to be busy days. 2 wires to run and hook up, the egr to install along with the knock sensor. Add coolant install battery and test drive!

[f85gtron]

The first startup after the chip is installed , you should expect:
Turn ignition to on position,
Check engine light should come on, flash off once, then steady on,
With ac selector off, radiator fan should NOT come on.

If the fan comes ON and the cel blinks rapidly or is out, then i screwed something up and the car is in limp mode.

[Raydar]

...limp mode.

I hate it when that happens.

[ron768]

Ok, got the car started today. Sounds like its running on 3 or 4 cylinders and will not stay running. The check engine light is steady on. I will be checking fuses and wire connections. Any help would be greatly appreciated .

[f85gtron]

Check bd6 and bd7 (probably black/white) and make sure they both ground out. Sounds like an entire bank of injectors aren't working.
Check Bc11 and bc12 too. That's where the injector wires come into the ecm, then go out through bd6 and 7.
Check the injector harness connector up by the map sensor, coolant neck area. The pins inside get loosy goosy if disturbed.
Check injector power supply (key on engine off) to the pink wires at the injectors to confirm power.

[ron768]

IT IS ALIVE!  Simple dumb mistake of not counting the pins correctly. I will let everyone know how it runs later. Thanks everyone for all the help is putting this together.
