hey all,

just looking for a little guidance on fixing my checksums. It seems like the mtx plugin is incompatible? Is there a way to do it manually? '02 A4 AMB 8E0909518F is the bin.

You can also post it in the checksum requests and someone will do it for you if you ask nice.

On the a4 ecu's and the MTX plugin always leaves the CRC uncorrected and so while the ecu seems to work ok, at somestage it will brick, maybe days, weeks or months, but it will happen. If you put the file through winols it will detect the error and correct it.. MPPS has the same issue. Only ever found this on A4 files.

So basically the only way I can tune my car is if someone does the checksum fix for me? :-/

I would love to. I'm pretty well versed in c++ but would have to brush some rust off though.

until then would ecufix get me going?

Just bought it. $140 is much cheaper than any other tuning options out there and I got a friend who will split it with me. Tuning these cars may be the death of me. I've learned so much and I still feel so small haha. Before this, all I knew of checksums was 'hey I've seen that word before when I was flashing my subaru.'

thanks again to everyone on here. lots of knowledge to soak up.

Ecufix. Just tested it. Works fine for my 8E0909518F. Still get an RSA signature failure but from what I understand that is normal and I don't need to worry.

I've read here that an RSA signature error is irrelevant, but for me, 2004 Jetta, it did matter.

I got locked out of the ECU twice due to this.  Had to boot mode flash the eeprom to get it to work again.  I then started using a different checksum tool which fixed that error, and have not had an issue since.

I would really, really, really like help from others to finish ME7Sum so we can be free of proprietary tools and capricious vendors.

Please! Pretty please!
