Help identifying TBI PCM/ECM

[Rkelley]

I pulled this from a junkyard. There wasn't enough information on the truck to really know which ECM it is. All I can tell you that the truck was powered with V8 TBI and It appeared to have an OD on the shifter. The numbers for identifying the PCM are rubbed off on the sticker. I know that the PROM appears to be BBMD.


I cannot find any information on that prom so as soon as I can figure out how to upload pictures I will get some up.


Currently in the process of doing a 4L80e swap on an '87 V20 Chevy.

The link above includes TBI with 4L80E information.

The recommended TBI computer for the 4L80E is the 16197427.

Thanks, looks like it's back to looking for an ECM.

Thanks, looks like it's back to looking for an ECM.

I was unsuccessful using the 16168625 with a 4L80E. Installed a 16197427, everything worked, including the custom PROM that had been in the 16168625.
