xHP Gearbox tuning information

We’re seeing more and more enquiries weekly for the XHP Flashtool gearbox tunes. This astonishing piece of software really unlocks all the BMW ZF automatic gearboxes, allowing for faster shift times, more power & better response. In this case study we’re going to look at the benefits, and the install process.


What can the XHP Flashtool actually do for my gearbox?


We offer three stages of tune for the ZF gearboxes, all set up slightly differently to suit different styles of driving.

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 gysflash one of the best on the market. 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 hook up to our diagnostic device, just to check the car out for any existing faults or problems with the gearbox, assuming it passes okay then we’re all ready to program. It’s skipping these simple measures that cause a lot of issues for the DIY installers!


We then hook the diagnostics unit up in programming mode, 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 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.


Is it really worth it though?

Yes, 100%. If you’ve had your engine tuned, you need the gearbox software done – we’ve never had a single customer give anything but 5* feedback on these gearbox tunes, and if you search around a bit on the web you’ll find much the same wherever you look. It really is a game-changing mod for these cars.
