Hello

I got the file and I played  it onto the cars ECU. Unfortunately it's unusable so as it it. I can not drive with this car with this mapping. I put fast the original mapping back and everything is ok again. Driving with gears  2,3,4,5 etc. always the same problem. As the turns reach ca. 3500 rpm car will immediately rattle badly. The rattle is very strong. As if someone quickly presses the gaspedal  and the brakeprake alternately. Gas-brake-gas brake, etc.   It breaks the car horribly, and I went back to the original right now. What happens next? What is the problem? Any mistake somewhere inside mapping?
