Hi guys,
I decided to modify my ECU, so I took a file with Mpps v18, full data via OBD.
I got the file that seemed to be correct. File was modified and while I was trying to load it to ECU (voltage above 13V, auto mode - so it went for CAN) it asked me if I wanted to do checksum correction, so I agreed. Then it was displaying "erasing flash" for few minutes and eventually "no reply from ECU" and that's it. No communication with ECU, mpps can't see it anymore.
I took the ECU out and hooked up KTag to it.
ECU communicated, took full backup and at the end there was a pop up message saying that there is a problem with checksum.
When I took individual backup of micro, flash and eeprom it let me do all of these, but I got message "checksum error" when taking backup of flash and flash file has strange size (only 544KB), EEPROM 8KB which seems to be correct and micro 512KB - this also looks correct.
This tells me I have problem with flash.
Is there any way of bringing this ECU to live again with tools I have?
Mpps v18, Kess, KTag, Inpa (Dcan+)
Maybe someone has this KTAG full read for my ECU?
Bosch edc16cp35/c
Bmw hw Id 07810980
Bmw sw id 07797506
Bosch hw number 0281015241
Bosch sw number 1037390902
File read by KTAG attached (this is after failure) - I can also post full obd read with Mpps (that was successful) if any help.
Can I please get any help?
