Multiecuscan

Hello,
I have a Ducato 2.3 130hp 6 speed manual with replaced gearbox. Now the cruise control does not work, but the system does not have errors. Cruise only works in 5th gear. In 2, 3, 4, 6th gear ecu does not see the gear selected, only when I put it into 5th gear ecu manages to calculate current gear and enables the cruise.
Is there a way to change the gearbox ratios in ecu memory?
p.s. I'm licenced MES user, but I might have posted in wrong room.

Did you changed your transmission with same part number?
Main problem is in different gears ratio or in ECU adaptations..
Try to reset self-learning function in ECU

I tried everything I was able to try with MES, but no help. I dont know what gearbox is fitted, I did not swap it, it came to me to solve the cruise not working problem.

drop VIN number. original gearbox was also 6 speed?
