Hello, I'm looking for a GM LS3 file. GMPP LS376/480 or the LS376/525 file. Need a baseline to compare to my tune. Thanks.

Here ya go, from memory the 480hp cal doesn't have the RPM limiter active and appears to be an error. These are from 2012 so there could be updated stuff by now.

p.s. From memory, the original files have the checksums disabled. I think I have the checksums corrected in these files.

Glad to help, roughneck is local to me and is a huge asset as a friend, especially when I get the Ford phone calls :happy: I usually stick with GM stuff or aftermarket, occasionally get a repeat customer who needs some Ford stuff and I want to publicly thank roughneck for the help :)

I have a really good customer who just bought a 525 crate so when I read it I will post the latest when I can.

All of them I have done have been E67 and now that you mentioned it, I will pay more attention and take pics of the back.

I mentioned that all of them have the checksums disabled so, what that tells me is they are real-time programmable. One day I'll figure that out, truly all it takes is to be able to write to ram cuz that is really where it lives when the engine is running. I haven't had time to research but I bet it is very similar to Mefi5 which would open up a lot of doors. :rockon:
