It came out of a 1987 Iroc, but the car had been converted over to a carb setup, and the computer was left in the car.

The service # is 1228079 and then under those numbers is 869041 M622591153. Any help would be appreciated.

Thanks

 

DA,

I wish I had an answer. I can't find a reference to that P/N on any of the ECM data pages I have.

Was the car running with that ECM?

Hey Vader,

Yeah I checked my sources as well and came up with zippo.

The car is not currently using the computer, it has a non computer controled carb setup on it at the moment. This was a 1987 Iroc and I have no clue what kind of induction setup it had originally. The only trace is the computer that was left behind. The computer had the wires connected to it and it was under the dash on the passenger side. Any thoughts?

 

I don't know if this helps but 1228079 is the ECM used in the GM 350 HO Conversion. Just one of the parts used to legally convert original LG4/L69 carb applications to ZZ4 350 carb. See the link below. Type 10185077 in the search for parts area.
