What can I say. Poor Kev spent ages on my car,a BMW Z4 sDrive 35i, not his fault, as the software from my cars ECU to his laptop transferred at a slow rate. Anyway, the job was done in a very professional way, Kev was very knowledgeable about the whole process. The test drive after the remap was an astonishing experience, the car now has monster urge, it was fast before but now it's amazing. The power delivery is super smooth, pulling cleanly in all gears from just above idle, its totally addictive, you guys have turned a great car into a brilliant one, well done! Anyone thinking of getting this sort of work done? do it! You will not stop smiling and all you will want to do is drive!

Alongside the engine control unit (ECU) we are also able to provide transmission control unit (TCU) software to help further enhance your vehicle. There is a lot of limitation built into modern gearbox software to help hold back the power gains you are trying to achieve from your engine, our gearbox software overcomes this and helps transform the way the car drives. Some of the modifications include raising maximum torque limiters, faster gear shift speeds, increased clamping pressures to prevent clutch wear, increased engine RPM limiters and much more…
