What Does a Gearbox Remap do?

Since introduction of the ZF 6HP transmissions in BMW vehicles in the early 2000s they remained a Blackbox for Tuners and car enthusiasts worldwide. While the ZF units have been tuned for many years now in other vehicles, BMW applied intense encryption and signature mechanisms to avoid Tuners and enthusiasts from doing so. While this is understandable from a manufacturer’s perspective, it does not satisfy the needs of BMW enthusiasts worldwide. The ZF-Automatics were used throughout the whole BMW range from the 1-series hatchbacks to the mighty Alpina B5 cars putting out around 500 bhp and 700 Nm of torque. While the hardware stays widely the same throughout all applications and is mainly divided in only a few types, the software inside the controller makes it possible to adapt the transmission to every vehicle and mimic a wide range of driver styles. Smooth and comfy in the Diesel applications, the same transmission in the Alpina B3/B5 come with a way sportier touch and make it hard to believe, that they are from the same breed.
