Got my ZF 8HP45 TCU tuned on my F30 335i. The difference is night and day. Shifts are way faster, almost DCT-like. Launch control works perfectly now, holds at 3500rpm and launches hard.
Highly recommend TCU tuning if you have the 8 speed auto. Its the best mod per dollar imo.
Launch control with TCU tune is addictive. My wife hates it but I cant stop doing launches at every traffic light lol
TCU tune is the most underrated mod. I did mine on my F30 340i and the shifts are incredible. Feels like a completely different transmission.
how much did the TCU tune cost? and can it be done remotely like ECU tuning?
