Hello cinqueturbo thank you for your reply this map, I was loaded about 2 years ago on my car from a "mapper" 3 months ago I had to replace from the turbine to the entire exhaust system...now I have the new map o ...I was wondering in the final part if I'm not mistaken, both the checksum 1fdf7c because it has the values 0 and I in bring the car back to version ori I left those values equal to the read that changes if I put those gold medals? ...1C356C if I'm not mistaken it would be the egr?... ecm speaks of the gas reintroduced, because of improving them?instead of decrease them? then in the map you see disabled the egr...from ignorance but with a desire to learn in the matter doubt of the knowledge of the guy to which I have entrusted to him 2 years ago ...about the time diesel is increasing all of the 20% to give more diesel, but without knowledge of the logical map of the turbo that varies in increments, I think of the case from 50 points to 200 ...even on the map the pedal does not seem to me suitable, in short, should I ricorrergerla or starting from 0 with ecm I can see the increments and maps out the driver who offers me the program... for those I need a help to understand their functions and someone that I could evaluate if I should leave them gold or keep the ones that we are
