Software calibration without the need for any transmission tuning or skewing the torque/load calculation model maps. This allows for accurate calculations, smooth shifting and no software trickery. The factory torque limiter is set to 440 Nm (325 lb-ft) at the crank. We are the first to offer a solution to lift this limit up to 1000 Nm by using our custom code! The limit is adjustable in app.

B46 / B48 cars are equipped with an 8HP50 transmission where the factory torque limiter is set to 440 Nm (325 lb-ft) at the crank. For the best results and proper smoothing of the torque curve without any transmission related torque intervention we have found that is best to increase the limiter within the transmission software. We present you with two options to implement this on your vehicle:
Option 1: Lifting the limiter in the transmission ECU which can be done for example with xHP Flashtool
Option 2: Bringing the car to our shop or another tuner for reprogramming of the transmission ECU limiters
