I'm waiting on an ALDL cable and trying to relearn how to use TunerPro RT, so I can do some datalogging and pin down a weird idle. When I bought this truck a few years ago I went through and took pictures of a bunch of things to have onhand as reference material, one of which was the ECM. 16168625, BDJZ...according to gearhead-efi, that matches to "93 C-K Truck 5.7TBI 4l60e with 3.73 or 3.42 gears" which seems very different from my 95 7.4 4L80E with 4.10 gears. Since I've never actually messed with GM ECMs from this era, could someone have swapped the ECM, and either reflashed or swapped the PROM to whatever the correct one is?
Rockauto lists the following options: 16196395, 16183247, or 16197427. Gearhead suggests 15156930 or 7427 (I'm guessing this is the one). Is there a decent list of BINs so I can figure out what I actually should have? Moates is shut down, and I can't find much else. The lack of an options list on gearhead describing my truck is probably because this isn't the configuration most tuners would want to work with.
