2. Open Winols, and after you will see the empty working box, picture 1A. Now drag and drop your ecu file onto this box as in picture 1B. Now in picture 1, you can see there are 3 checksums that need correcting, Winols will do this for you.
3. Follow the instructions in following pictures and this should get you started making checksum for your own files.
Run Winols
Drag petio 3,.0 asn_lambda_off_nochecks.bin into Winols
You will see the pop-up: 3 checksum(s) not correct
Correct the original data file
Map search in progress

Save as petio 3,.0 asn_lambda_off_nochecks_csok.bin

FAQ:
Q: I found a stage1 tuning file and while I was inserting it into Winols it says me: “This software version cannot be processed, since it is already modified” Could somebody please help me what does it mean?
A: Open the file in a simple hex editor, click search txt string NOREAD
when you find the words “noread” write over them with FFFFFF, save changes and try again with Winols
Q: If I read and write files with Kess V2 or KTag clone did they make checksum correction or must be done with Winols?
A: With those tools checksum will be done in writing
Good luck!
