The difficulty with the modern day vehicle is the inability to tune a vehicle's transmission to release the engine's true potential. The transmission always has the last say in what levels of torque and power get through to the road.
Chips and Piggy backs can never access load limiters, but even the best ECU tunes cannot access the transmission load limiters on modern gearboxes and therefore there is always more torque and economy to be had. Certain transmission tuning has been available for some time, yet nothing has been able to tune a number of marque's and especially, 'untunable' gearboxes from the likes of Toyota, Lexus, Mitsubishi, Mazda, AMG, Porsche, Lamborghini, Ferrari, BMW and many others. This tool is not only able to tune almost any gearbox in existence, but can be done through the OBDII Port, and is done in seconds.
Gearbox response and shifting between gears can be improved as much as 50%, whilst being smoother, and depending on the vehicle, includes alterations to shift pattern, shift point, launch control, clamping pressure, converter lock-up, torque limits and more.
