Computer ID number

[British Slave]

I'm having a few issues with my Bazer at idle and cold start. I noticed today while working under the dash, a bar code on the computer. Is this the model number? It doesn't match what suppliers list for my truck.
The number is:
869931M710522452
and
16069931
and
ACSU
All that is on the sticker on the computer.

What's your truck?

There are some ECM with differant numbers that are identical to what usually comes in the trucks this site was designed for which is a 1227747.

87 with 350 TBI

Sounds like the correct chip (BCC) and a remanufactured GM ECM so I don't think that is your issue.

I really wasn't looking for a solution to the idle and cold start, just happened to notice the label while procrastinating on heater core removal. I was just wondering if it was right. There are a lot of things the PO did that I'm never surprised at what I find.
