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! Just like a windows update on your PC or your phone which has an OS update, a gearbox update is similar, designed to improve the overall functionality and usability of the system it controls.
A gearbox update is very different to a gearbox remap, when we remap a gearbox 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. (Currently we are working on gearbox remapping on VAG DSG gearboxes). With a gearbox update we do not modify the data, we instead use dealer diagnostic tools to update the ECU calibration file to the latest software. 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 and at present we can update Citroen EGS gearboxes however some of the common vehicles are BMW’s with ZF gearboxes, Mercedes with 7G-Tronic and MCT and we are currently expecting these to become available in 2017.
