Good info. I'm not sure what GM actually called this second set of HS GMLAN ID's, but it would helpful to categorize what PCM hardware OS versions ran it. For now, at least ya know what your lookng for in the ID structure for anything in question. If CAN ID's are all dec, it's Corvette / Holden ver...

Love reading this stuff. Thanks for sharing. I wish I had something to add, but all I can offer is gratitude.

I checked my CS+ install and it doesn't have any of the PRM files you're looking for.

PRM is for 78K and V850. PR5 is for RL78.

I've got an old Colorado IPC circuit board I was about to throw away. Let me know if it can be used for destructive testing or something.

I can't believe they even offer programming via ELM type devices. It also blew my mind that Ford thinks it's acceptable to take 9+ hours to program a cluster.

2018 F150 8" cluster in a 2017 truck. I did a quick skim of the code associated with the high range DIDs and it looks like none of them do anything especially interesting.

This is pretty amazing stuff. Nice work. Is F2A9 a standard DID for Ford CCP? I've been chipping away at the software for a newer truck cluster and I don't see that DID in the list of 2F sub functions. So do I just assume CCP isn't supported on this module, or do I need to dig into each of the unkno...

Damn. That is really cool. Nice work.

Looks like a lot of the EcoBoost controllers are typical Bosch hardware. Possibly MED17.x variants. I haven't dug into it too far yet.

Caught me off guard when I first logged in, but I'm liking it now that I've had a chance to look around. Seems a little snappier too.

I second what Cincinnatus said about the thread index.
