Hello,
I have the new TCU tune with the 4-Mode what you can change with the W/S switch. After driving it now for over 400 miles I'm mostly happy with it but I have two problems. So I want to ask others with this tune if they have the same issue.
First if the outside temperature is under 45°F the TCU changes the gears only above 3000 rpm, that's a lot to high for a cold engine. OK, you can go in manual mode and switch but that's not a real solution. If you drive for 10 minutes and the transmission gets warmer the issue disappears.
The second error is in manual mode. If you accelerate full throttle and come into the engine limiter the gearbox switch to neutral and you can't switch any more also in other driving profiles. You have to stop, switch the engine off and start it again to solve this issue.

What are your experiences with this tune?
