BCM tune for speed limiter removal on GMC trucks
Posted: Wed Jul 13, 2022 4:24 am
Is there any way to tune a BCM from the latest versions of GMC trucks to free the speed limiter? If so, any idea how I could start?

Mind sharing where you saw that the bin file can be read?? I'd be interested in something like that..hidalga wrote:Yes, any 2019+ GM BCM, I'm aware that there's a way to read the bin file, but I don't know if there's a checksum, seed/key algo, where should I look at so I can free the speed limiter
Immo related tools will read and write them since they are designed to clone the BCms to copy security/key data to other BCMsironduke wrote:Mind sharing where you saw that the bin file can be read??

Thanks, I think I was a little too excited and assumed he meant something open source or at least somewhat inexpensive.. lol.. I have no need for this, just would like to see it for myself, lol..Tazzi wrote:Immo related tools will read and write them since they are designed to clone the BCms to copy security/key data to other BCMsironduke wrote:Mind sharing where you saw that the bin file can be read??
