Since the introduction of
...
ZF 6HP transmissions in BMW vehicles in the early 2000s, they have remained a
...
black box for
...
tuners and
...
enthusiasts worldwide. While the ZF units have been tuned in other vehicles for many years
...
, BMW
...
has used extensive encryption and signature mechanisms to
...
prevent tuners and enthusiasts from doing so. While this is understandable from
...
the manufacturer's point of view, it does not
...
meet the needs of BMW enthusiasts worldwide. The ZF
...
automatic transmissions have been used throughout the
...
BMW range, from the 1-series
...
hatchback to the mighty Alpina B5
...
, which produces around 500bhp and 700Nm of torque. While the hardware
...
remains largely the same
...
for all applications and is mainly divided
...
into just a few types, the software inside the
...
control unit allows the transmission to be adapted to
...
each vehicle and to mimic a wide range of
...
driving styles. Smooth and
...
comfortable in
...
diesel applications, the same transmission in the Alpina B3/B5
...
comes with a
...
much sportier touch and
...
makes it hard to believe
...
that they are from the same breed.
...
Optimizing your transmission is not
...
just about
...
going faster or
...
having more power. Few people
...
realize how
...
much an automatic transmission contributes to the overall driving experience. From crawling in traffic
...
to city driving
...
to taking your
...
car to the drag strip or
...
racetrack, the TCU
...
largely defines how your car feels.
...
Just as everyone drives
...
differently with a manual transmission, the maps
...
in the TCU
...
hold the secrets to
...
tuning your automatic
...
to your personal
...
preferences and finally
...
experiencing what BMW promised you
...
in the glossy brochure:
Sheer driving pleasure!!
...
Overview
This
...
wiki will guide you through
...
flashing your TCU (Transmission Control Unit)
...
with xHP.
...
We've done everything possible to make this process
...
easy, safe and smooth
...
. However,
...
tuning a vehicle and flashing
...
ECUs in a car always requires
...
attention to certain things and prerequisites.
...
The following pages list the
...
requirements and how to avoid
...
problems
...
before they
...
occur.
| Info |

The flash method used by xHP is 100% safe for your TCU! You |
...
won't be able to brick it. |
...
Prerequisites
...
Use the correct hardware to safely flash your TCU
...
and prepare your vehicle.
...
Please make sure you
...
don't have any mechanical problems with your gearbox. xHP won't fix bad mechanics. Never. If you're already experiencing jerky shifts, mis-shifts or bucking, your transmission probably needs to be serviced or repaired before you flash it.

Supported transmissions
xHP is
...
designed to flash ZF6HP/ZF8HP and DCT (Dual
...
Clutch) automatic transmissions in
...
BMW vehicles. It
...
won't connect to or work on other
...
car brands or
...
automatic transmissions.
The ZF6HP/
...
ZF8HP were BMW's automatic transmissions of choice for
...
almost their entire range from the early 2000s
...
to the present day, while the DCT was mainly used
...
in M
...
cars.
Mapping a transmission is a tedious task and has to be done on the road, specific
...
to a
...
particular vehicle.
...
That's why we can't support "all" BMWs in one go.
See here how to check for
...
support for your car!
If it is not yet supported, it does not mean
...
it never will be. Please like us
...
on Facebook or Instagram for any updates on supported vehicles, or
...
email us at support@xautomotive.com.
...
We'll be happy to
...
add vehicles if there's enough customer demand!
