I know this problem but from another ECU. In my case the swapped gearbox hade not the same transmission ratio so I have to adjust the transmission ratio in the engine control unit.

I´ve found these three maps for gear detection (speed/rpm)
can anyone help me with modifying these constants? I don´t know if lowering or increasing values and where... Undecided

Kfgang.2 map content copy to kfgang.0 and kfgang.1 maps + little mods for 5th gear in lower rpm.
So values for longer gearbox needs to be increased. Now cruise control working on all gears. Maybe not 100% clear solution, but working for me.

Very nice to see your fast repply after problem was solved Wink

I haven't problem share this solution.
