Retro's 1989 GMC Sierra C1500 Sportside Indy clone

[HotRodPC]

Went to the junkyard yesterday and while I struck out on what I needed, I did find a BRAND NEW Delphi 16198445 ECM in a wrecked 1989 GMC S15 2.5. Swapped that in and what a difference, throttle response is better, it doesn't die when I start it now. Highly recommended if you can find one. They had another but it was original to the truck.

So you're running it with the S15 ECM and the orignal PROM chip that was in the S15 2.5? Am I missing something here? You have some splainin' to do. Tell me something I don't know. I'm confused.

Interested in the ecm info as well

Using the 5.7 chip. The 445 was a service upgrade for the '165 ECM, it has the same hardware but different software. If I recall correctly, there are injector driver and fuel table differences.

Sierra got a new set of 4" FMPs.

These wheels have been passed around GMSB like the clap.

Are those the ones I had Old77 pick up for me in MO, and then I sold to Frank?

Yep, then I bought Frank's 98 for my wife and they came with it.

We had many but none worth comparing to polished up square body wheels
