If you read the file from the ECU and tune on from there, it should be ok. If not, I really don't know what to suggest, other than see if any tuning changes exist in the bottom 2 blocks and reverse them.
Let us know if you find a solution.
Good luck!
Blocks order depends on the xml definition file, the bottom two that I have are 'idle control' & 'diagnostic trouble codes' are these the meant two blocks? Strangely, I'm unable to flash the car own original stock file over the current tuned one! Two years ago I flashed the car with an updated rom version without any issues.
