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

Hey guys, short update and a new question. I got everything to work and have no issues with the Roadrunner besides I need to disconnect the USB before I boot the ECU is that normal? I figured out that there is 4.6V on the DQ15; 5; 4; 3;. Is that normal? Or is something damaged on the roadrunner?
