A team of Automative software developers

JR Tuning is based in Kent, with our workshop located 15 minutes from Maidstone. We provide Engine ECU and Gearbox TCU remapping software developed in house to provide an improved driving experience. This is achieved through both power gains, a wide power band and through better throttle response. In the case of automatic gearboxes, faster gear shift speeds, earlier lockup and an improved shift pattern are possible.
