Hello,
send my file to a service for ecu tuning, and they said that my file cannot be tuned, because some of my maps are missing?
I have DPF and lambda removed. The other stuff is untouched.
Can you please check the file if it's okay? Downloaded it with KESS.
I want someone to tune it if it's possible. Thank you!

use the recovery mode in kess v2 this will bypass the checksum correction

are you using an original Kess tool?
the original tool correct automatically the checksum

did you write the modified file?

test this file, has a better performance and EGR off. just solve the issue with checksum with your KESS read and write tool.

after that i can send to you the final version.

kind regards

atejedav thanks.
From writing i got "generic id error"
From recovery i got the checksum error again.
I use some european kess v2 model, the more expensive one.

Hi.

given is a clone tool, you will need to correct or fix the checksum issue prior to be able to write back the tuned file.

original tools correct or fix it automatically at write time.

Kind regards
