Greetings.

I had to swap my car's gearbox since repairing was not a cheap option. The gear ratios are the same except for the final drive. My car runs 225/45R17 tires and the Corsa 215/45R17. Both cars have Bosch ME 7.6.2 ECUs.

I thought about copying over (what I think it is) NVQUOT1O (upper quotient for 1st gear), NVQUOT1U (lower quotient for 1st gear) up to NVQUOT6O, NVQUOT6U for 6th gear values from the Corsa OPC's dump to my Astra's dump. The final drive it's about 6% shorter so I would expect these values to change about 6% but they don't, the change it's much bigger and different from quotient to quotient but I might be wrong by thinking this way.

I need guidance to understand how to recalibrate these values. I guess it would be easy if I knew either which nmot_w or vfzg_w to calculate the upper and lower quotients.

I don't have logging tools but I might be able to source some.

I appreciate your help. Files attached.

Thanks.
