	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

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.
