W210 EGS52 help change ratio to 2.87 from original EEPROM

Hello everyone!Please help me recalculate my original factory EEPROM file for a Mercedes W210 EGS52 TCU. The car is a W210 sedan, and I have installed a new rear axle with a 2.87 gear ratio.I tried to modify the AA 22 variant coding string manually in a HEX editor, but the TCU goes into a hard limp mode (stuck in 2nd gear) when the car starts moving. It seems there is a global checksum or offset mismatch.I have attached my clean, untouched, original factory EEPROM file (.bin) read via K-Tag on the bench. Could someone please modify this original file correctly for a 2.87 axle ratio and recalculate all necessary checksums so the gearbox works without limp mode?Thank you very much in advance!
