Title: How would I begin to do a checksum on Simos 3.3
Post by: Rick81 on November 18, 2024, 04:38:41 PM
I deleted a dtc did checksum flashed it everything went well starts up fine.

Winols doesn't seem to do all the checksum for all dtcs . I have more dtcs to delete.

Where would I start or if I was to correct it manually is there a program to use .Am I correct That Simos 3.3 is an 8bit ?

Kind regards

Just contact EVC if there is a problem in Winols checksum, they have great support.

I get that . I would like to learn how to do it manually . If i went down this route is the checksum actually in the map itself. Does it start or end with a zero? And when checksum is corrected does the modified file just need the checksum to read the same as the original file or should i say match up. If i use tuner pro from what i understand it will only except a bin file and not just file well the free version anyway

On hex editor I'm comparing files. If I go to checksum section in picture attached I'm not sure what it means
