Short long story, I have 6HP on M7.1
Now I want to change gearbox, but I don't want to relocate sensor (6HP have sensor location like manual gearbox) and on my curent gearbox I need to relocate sensor to be in same position like on 5HP

Is it posible to change that in software? To tell ECU that sensor is on different angle?

one mechanic I know who assembled such cars said that yes, it is possible. as well as PWM control of the fan block. he didn't change anything, just connected the wiring and everything worked. the flywheel remained original from 2.7

without modification of the flywheel or gearbox housing. without replacing the fan control unit

Easiest solution would be to redrill the flex plate for the correct offset

That is how is now made on car. But it is really on strange place, aluminum there is too thin
I need to weld also not only drill hole
