Title: Dq250 ratio swapping Post by: andyc1234 on April 15, 2022, 03:38:55 AM I have fitted an 0d9 mqb dq250 into a non mqb car. I have fitted an earlier non mqb 02e mechatronic and I have had the ratios copied over from the 0d9 file into the 02e file and the car runs and drives but iam having problems with it not wanting to upshift. I have noticed in my logs that my vss speed from the abs doesn't match the gearbox calculated speed. I edited my wheel speed settings on my ecu so they both match just to test and that seemed to make things worse. Still wouldn't upshift and then started throwing output sensor errors. My question is. Is there something else in the tcu mapfile were the gearbox calculates its speed on top of the data areas for individual gear ratios?
Iam at the point of just swapping the whole gearbox again to the correct gearbox and not having to mess with any of the ratio data but it would be nice to get it to work as it is |
