Did you bother trying ME7Sum? If not, why not?

Does the file have AL/NLS?

yes i did try ME7sum and no it doesnt have any of the add on's because it came from an automatic car.

Here's the output from ME7sum.

*** Found 70 checksums in 06A906032NL.bin

*** WARNING! 1/1 uncorrected error(s) in 06A906032NL.bin! ***

So tell ME7Sum to output a corrected file.

i feel like an idiot, i didnt realize i had to add the output file name to it. thank you nynet. problem solved!
