Hello I'm looking for an damos or project file with map locations specifically transmission data. This is for a late b8 2.0tdi caha manual but caga should work as well as long as its cp20 I believe.

I've found the A2L for the same ECU, albeit with a slightly older (5489) software version. By comparing the two, you should be able to find all the necessary information.

I also changed the gearbox and had to change some transmission info in the ECU to enhance ride quality and regain the lost cruise control functionality.
Although I don't recall the specific parameter names or IDs, but the process was relatively straightforward.
I remember setting those parameters by logging both the engine speed and vehicle speed, then calculating the ratio of vehicle speed to engine RPMs.

Here is the DL link, as I'm unable to upload 3.2MB

Thank you, I was able to DL it. Hopefully I can get cruise to work now, this car has a 8 speed trans on the 6 speed manual ecu. I found the maps for the different gear ratios and can get the display and cruise to work for 1-7th actual gears showing 1-6 but no matter how I calculate 8th gear it won't accept it as 6th.
I can't figure out tprot either so I have to keep pulling the ecu to write to it on the bench  Huh

I'm not sure if I want to open a can of worms, but isn't it easier to flash a CVT's ECU firmware onto MT ECU?
