Title: Checksum Patch and Immo Off for RoadRunner Post by: Nate211 on April 13, 2026, 11:51:41 AM Hello Guys,
I need some help with my Roadrunner project. I managed to fit the Roadrunner on my Me7.5 and designed some PCB‘s and a new soldering header so I don’t have to solder the EPROM on and off every time I want to know if the ECU is still working. If I plug the EPROM broad onto the Ecu the it boots. I use Ktag for bench flashing by the way. First I thought something is wrong with Byteswap or my file and read it with my eprom programmer. Everything was fine with. Input and output are exactly the same. I read something about deactivating the checksum or something about a patch can someone explain how that works? Is it the ST95040 or the ST10C167 flash. Sorry for my bad English. Greetings |
