	ME7.5 1.8T DQ250 communication « on: December 28, 2024, 10:33:31 AM »

Hello i swaped a Seat Leon Cupra 1.8T from manual to DQ250 transmission. The ECU 1ML906032A already tuned with Stage2 cannot be coded with VCDS. Have i swap to a different software version and can the tuned maps be taken over again without new custom mapping?
Thank you for your help.

yes, it can be done with your Stage 2 file,
but DSG needs proper torque values,
usually this will need some extra work on relevant maps

What exactly needs to be changed?
