Working on an 07 Audi B7 S4 and im having a hard time getting the eeprom off the ECU. Normally it figures out the CSpin on its own... This 8e2 ECU is giving me a hard time though.

Can someone help with what the pin is i should be putting in? I tried P6.0 till P6.7 where it errored out after that in the EEPROM tool.

Thanks in advance.

Pin is P6.3
Can your eeprom tool work with ST10C175 MCU ID value (ID=0x1143) ?
It is different from ID of С167CS MCU
Below is eeprom read log of this type ECU.
Att! EEprom read tool was patched to recognized ST10 ID!!

Thats what im talking about. Thanks Gremlin. I was using the wrong chip type in the request because im used to 95P08. Ill test with that instead and see what happens! Appreciate the feedback (A-LOT)
