Gearbox Software Update

Updating the gearbox software on a vehicle can improve the overall driving experience by resulting in: quicker shift speeds, better MPG, smoother gear changes, less clunking or delayed gear engagement, and more! A little like windows updates on your PC or your phone has an OS update, a gearbox update is similar, designed to improve the overall functionality and usability of the system it controls.


 Gearbox (TCU) Software Update

A gearbox update is very different to a gearbox remap, when we remap a TCU (Transmission Control Unit) we extract the data, modify it, and then reload it back in to the TCU. A gearbox remap is normally carried out when trying to increase vehicle performance or for making substantial modifications to the gearbox characteristics. With a gearbox update we do not modify the data, we instead use OEM diagnostic tools to update the TCU calibration file to the latest software revision. We connect our equipment to the vehicle, the diagnostic tool will check the current TCU software revision and if a newer one is available it will be downloaded straight from the manufacturers online server and programmed.

Most models will benefit from a gearbox update, however some of the common vehicles we see for this service are BMW’s with ZF gearboxes and Peugeot / Citroen Models with EGS (Electronic Gearbox System). Gearbox updates are only available at our HQ in Bristol.
