The most popular upgrade for us at the moment is the Stage 3 tune on the BMW 335D – these cars are developing big power now, and were only available with the automatic gearbox. Being able to change that box from something designed for comfortable cruising to a responsive sporty setup makes all the difference for the guys who are using these cars on the track.

SO HOW DO YOU ACTUALLY INSTALL THE TUNE?

We start off by connecting the car up to a battery stabiliser. This is very important as the TCU is sensitive to voltage drops when programming – a voltage drop can cause failure of the TCU unit, and leave the car undriveable.

We then connect to the car with the XHP software, and unlock the TCU for programming. At this point the car is then able to accept any of the OTS XHP maps.

With the correct map selected, we then begin the programming process. Start to finish, this takes around 30mins to do including all checks, so can be done whilst you wait.
