Anyways everything was the exact same from 0xF17A and down, but there were differences before that here and there.. That section isn't calibration or operating system area, eeprom? registers? etc I imagine..
Looks like it worked though!!! Excellent!!!
Tried modding the bin I read, did the CVN, then the SUM and then wrote it just fine.. Read it again and it looks good to go!!! I wonder if I HAVE to change the cvn?? or if I could leave it alone?? lol..
Wow, fantastic. Didn't expect the GM MDI work right from the spot with my first implementation of passthru 8)
Thanks for your testing.
Can you upload your dump here?
Did you need to check the "ignore DLC! = 8" box?
All the register stuff is at 0x2FXXXX and higher. I have to have a look what is there at 0xFxxx.
Files read by other tools seems to blend that out with 0xFF.
Remember that only the calibration area will be flashed, so no risk.
As far as i understand the code, you have to fix the checksum, otherwise the code will not start.
You do not have to recalc the CVN, but you will get an error code (DTC) that it is wrong if you not do so.
