Does anyone have a read from a 2020 or 21 ecu with HPT yet?
I saw they came out with support for this last week. does it require you modify the pcm before you read it or flash only? i have one here i can read out.
Gotta mod the PCM first to get the time sensitive revolving lock code out of the way.
Supposedly they can flash via obdii after! Sure send em my way can never have too many binary dumps lol! [email protected]
i think they are using an unlock tool that changes the boot loader, just like the l5p duramax stuff..
