	ME7 Checksum checker not liking ori « on: August 13, 2015, 06:46:42 PM »

I have read a ME7.5 (Octavia VRS) ECU using Galletto v54 in boot mode. The file read correctly and appears to be a good solid ORI. I tuned the file and attempted to use the ME7 checksum corrector tool and it was unable to fix the file. I thought I'd best test the ORI to see if I somehow broke the tuned file, but the ORI is also failing the check. Is the read bad? (attached)

Code:

├¥ Opening 'y:\ecus\Ross Octavia VRS ECU\read' file
├¥ Getting length of 'y:\ecus\Ross Octavia VRS ECU\read' file
├¥ Allocating buffer of 1048576 bytes
├¥ Reading file to buffer
├¥ Validating size correct 1048576=1048576
├¥ Closing file

No, the read is likely good... ME7Sum just doesn't support that file Sad

If I have time I will try to add support

Thanks for getting back.

Just as an update, using MPPS to CHK the file, it then writes to the ECU on the bench no problem. Where there's a will there's a way.
