I`ve tried to write a modified file into EDC17CP02 and it failed to calculate checksums by giving an error.
The file was already Stage 1, partly DPF off, EGR Off, so what I did is corrected DPF Off , EGR Off solution and added Swirl Flaps, Speed Limiter and Readiness Calibration.
I have tried a few times with auto checksum but it gives the same error on every try. So I had to do checksums by Winols.
Please check it and if needed I can provide all the files I used. Thanks

why you make 2 same threads??

why you make 2 same threads??

obviously because it gave me an error when I tried to do it first time , so I did it again. Would you like to moderate and delete it for me as you have already asked about it?

even now when I try to delete it something went wrong at the beginning

however it`s been done now.

If you have the original file from the ecu please use that file for checksum correction. The checksum error mostly because of the file already edited before. Please contact support team to check the files further.
