Anyone can guide how to solve a P0601 issue? ECU SW is 1P0907115H 0010. I was looking for a SGO without any luck. Attached is the eeprom with the P0601 error.
I appreciate your comments.
Thanks,

The problem will be in the flash. Have you tried fixing the checksums? Post a flash.

I come back to OEM flash (checksum revised too) and P0601 DTC persists. Also check checksum of previous attached eeprom, was ok too.
Car has a really weird condition, intermittent misfires, very rough idle, hesitation under acceleration and does not pass 2000rpms.

Did you cross flash it on the bench? If so that's your issue.

No. It is the OEM SW version. A tune was charged. Car was working really nice by 2weeks. After 2h in a trip, car starts to produce the mentioned behaviour and commented DTC appears.

Sorry friend I confuse a previous version of the tune. Ok anyway attached is original file from car. BWA is the engine. Car is almost original. Only mods are a catless downpipe and high flow air filter. Right now car is back using it original file, but the P0601 DTC remains there.

Flash is fine. Try this eeprom. If the problem persists. Reflash Ecu with 1Z0907115D. Then compare the flash and change maps from the ori file. Its same damos version and engine.

I am not that familiar with fixing an med9 eeprom.
maybe you can flash 1P0907115_0040.sgo and eprom will fix on its own?

gremlin and basano should be med9 specialists in here
