Of course. Figured there's got to be at least one guy out there that it helps, and it wasn't that much trouble to post what I have. I am having a few issues, I'll post up separate threads so hopefully I can get specific help for them. My idle is off and truck doesn't like to start(pretty sure it's a tuning issue for the new cam not being right), also having a technical issue with my PCM staying locked, but I didn't lock It(at least not on purpose) and it flashed fine the first couple times.
Had to post an update today, 5/22/2022. If you downloaded the bins I had posted before today, Titled "02express5.7withS104l60e4x4 os12212156", Don't use them. I updated the first post with revised bin files that should be the same as promised. Long Story Short, the 02 Express van bin I used as a base to start from from the "LS_Based_Engine_Repository-master' zip file was corrupted. It doesn't look like it, everything edits fine, Checksums fine, Flashes fine. But when It gets flashed on, for some reason you cannot ever unlock the PCM Normally. Never figured out why, but had to start over with another 02 Express L31 tune(2500 this time) and segment swap the s10 4l60e4x4 stuff in. Should all be the same same as the first posted tunes, but no issues from these ones. IF you did download that tune bin in the first week and flashed it, you can unlock your PCM with the "ground pin method" like I had to do 47 times to figure out the issue and get a good unlockable flash running. I'll post up the link to that ground pin unlock info.

This is exactly the project I am researching info for! Thanks!
that's because the express 4l60e tune in the 2002 bin files thread has corrupt eeprom segment - the seed key is 0xFFFF
i discovered this as well when i did a "write entire" or clone. had i just written the OS, parameters, and cals, then the ECU would've retained its own eeprom segment and everything would've been fine. live and learn :)
take note, developers of PCM hammer: yell at the user before they do a full write/clone with seed key that is corrupted
Thanks!
My name is Mikey and I'm new to the forum. I'm just gonna borrow some of these sweet tunes, thanks.
