I was tuning my car yesterday and after saving and reopening the file to my surprise the fuel & ignition tables are all messed up! WTF!!!!

Thank god i could get the tuned maps back from downloading from the ECU (P28). Scared my to death since it's my first time tuning.

I have checked for new updates already and i automatically installed a firmware...

See the pics below of the saved calibration files...

 

That does happen sometimes. The file gets corrupted. That is why you want to save your original tune before making any changes. As you tune the vehicle save the file at various stages as tune1, tune2, etc. Just in case.

 

Thanks, are there any software updates or something else i need to know for solving this issue?

 

It looks like you have the latest version of S-Manager. It should not happen often. If it does, your laptop may have some issue.

 

Ok last night i tried again and it seems that if i save the file while the ignintion is just turned on the file seem to get corrupted. However by saving the file while the engine is running the file doesn't get corrupted.

Hope that helps someone else in the future. That solved the problem for me anyways.

 

Describe carefuly step by step exactly what you are doing. It sounds like you are reading hte calibrations out of the ecu and that could be the problem.
