LB7 duramax stuff
I see that PCM hammer supports the LB7 Duramax, I'm slowly piecing together a LB7 for my 86 Suburban, I downloaded a stock bin file (still wiring the truck) and attempted to load it into universal patcher, and I'm only getting DTC tables, does UP not support the LB7?

Re: LB7 duramax stuff
I think the pcm is called the E54. And its only in the test versions, not widely available yet, of pcm hammer. Plus yes, not well defined. You can work with it, but its still early days.
Have you read the FAQ? For lots of information and links to significant threads see here: http://pcmhacking.net/forums/viewtopic.php?f=7&t=1396

Yep thats an E54 pcm. Not much out there open source yet. I did start to put together a xdf. Looks like the checksum calculator for the p01/p59 works well with it so either add that to tunerpro or use universal patcher to correct the checksums

Thanks for the help! I was hoping to find a little magic bit somewhere for the fuel pump relay, but it probably only existed on cab and chassis trucks with dual tanks. it would be awesome to be able to set it up to run my lift pump, but I don't think that will happen.G-Body wrote: Sat Apr 04, 2026 9:14 pm Yep thats an E54 pcm.
