    I posted several screenshots of various airflow settings. The bottom left number is from the compare file from original ecu still in car. The numbers are such large differences, it makes me wonder if the xdf file for the 2088 os cant read the old os from ECU still in car. Is it possible to swap segments, like fuel/trans between different os versions ( I'll bet not)? I believe the fuel injectors in 2001 are larger size than in 1999. I'm looking forward to installing the new ecu in the car and see how it runs. Then I can just make small changes and write to ecu, or are the numbers in fuel and volume efficiency so far off it would hurt the engine if those numbers arent dialed in first. I'm learning a lot, reading and trying, but any insites you can offer would be greatly appreciated. Thanks again for all your help.


    I dont see the screenshots, so I'll post them again.
