BMW xHP gearbox remap in Kent, on your driveway.
The ZF eight-speed in your BMW is one of the best automatics ever made, and BMW set it up gently. xHP is the established software for it. You get faster, firmer shifts, torque limits that match a remapped engine, a manual mode that holds the gear, and a list of features you choose from. We install it at your home or work.

ZF 6HP and 8HP, which is most of them
Eight-speed, 2010 onward
This is the box in nearly every automatic BMW since the F-series, from the 1 to the 7 Series and the X3 to the X7, in petrol and diesel, including the M Performance cars. The 8HP45, 8HP50, 8HP70 and 8HP75 variants all take xHP.
Six-speed, E-series
This is the box in the E90, E60, E70 and E71 generation automatics. It is older but still very good, and xHP makes an even bigger difference to shift speed on it than on the eight-speed.
Toyota Supra and others on ZF
The same ZF 8HP is used in the current Supra and in a few other makes. Where xHP supports the box we can do it, so send the registration and we will tell you.
xHP, feature by feature
xHP comes in stages, and the features are chosen to suit the car and the engine map. This is what is available, though not every item applies to every box.
- Faster gear shifts - shifts are quicker across the board, most of all in Sport and manual.
- Raised torque limiters - so a remapped engine is not clamped by the gearbox in the lower gears.
- Raised clutch pressure - the clutches clamp harder under the extra torque, which protects the clutch packs.
- Full manual mode - the box holds the gear all the way to the limiter and does not change up for you.
- Kickdown delete - a floored throttle in manual no longer forces a downshift.
- Auto upshift delete - the box stays in the gear you chose.
- Soft limiter delete - the early, soft rev limit is lifted to the engine's own limiter.
- Launch control and shift points - where the box supports it, launch control enabled and Drive and Sport shift points tuned to the engine map.

xHP, the questions we get asked
Which xHP stage do I need?
Stage 1 suits a standard or Stage 1 engine where you want sharper shifts and a proper manual mode. The higher stages are for cars with more torque, or for a driver who wants the firmest shifts available. We recommend the right one for your car and the engine map it has, so you are not left picking from a menu.
Will it make the car jerky in Comfort?
No. Comfort stays comfortable. The change comes in Sport and manual, which is where you want it.
My engine is remapped. Do I need this?
On a remapped BMW it is often the 8HP's own torque limiter that holds the gain back in the lower gears. Raising it is what lets the engine remap deliver what it promised, and most people who do both say they wish they had done the box first.
Does it affect my warranty?
A gearbox remap can affect a manufacturer warranty on the gearbox in the same way an engine remap affects the engine. If the car is under warranty, read this first. The original file is kept and goes back on one visit.
How much does it cost?
We quote it on the car and the stage you need. Send the registration and you get one fixed figure before anything is booked.
