xHP Gearbox Tuning

xHP Flashtool is the world's first and only complete tuning solution for your BMW with ZF6HP, ZF8HP or 7-speed DCT automatic transmission. xHP focuses entirely on getting the most out of your automatic transmission and is the world's leading solution for BMW vehicles. 

We offer three levels of tuning for the ZF gearboxes which have their own specialisty depending on application and personal preference. Please see the below for detailed information on each one;

Stage 1 Features:

The Stage 1 files focus on economy and comfort, by upshifting early in D-Mode and locking up the torque converter sooner, compared to the factory calibrations. MPG gain to be expected (depending on vehicle and driving environment) between 5% and 15%.

• Gear Display in Dash in all modes (where available)
• Early torque converter lock-up
• Shift strategies altered for economy and comfort
• Adapted torque limits for tuned engines

Stage 2 Features:

The Stage 2 files are for people who want faster shifts and a more responsive driving experience, but not to sacrifice any comfort.

• Gear display in Dash in all modes (where available)
• Optimized D & S shift points for better acceleration in part and full throttle situations
• Approx. 25% faster shifts overall
• Faster paddle response time
• Optimised Torque Converter Lockup in 1st/2nd/3rd gear

Stage 3 Features:

The Stage 3 files are our most sporty calibrations, changing the driving experience totally. While all Stage 3 files retain full comfort and can be used in every daily car, the behaviour changes when switching to S or M. Massively reduced shift times and throttle blips in manual mode show what your auto transmission is capable of. On top of Stage 2 features include;

• Torque limits raised to maximum
• Approx. 25% faster shifts in D mode
• Approx. 50% faster shifts in S and M mode
• Rev-matched downshifting (Throttle-Blip)
• True Manual Mode (no forced upshift at RPM limiter)
• Instant paddle response time
• Raised line pressure for better holding power!
