RENNtech R1 Performance Package for McLaren MP4-12C 2011-2014

RENNtech has been at the forefront of ECU tuning since electronic engine management started to show up in vehicles during the mid 1980's! Our experience, countless hours of in house research, development and exhaustive testing ensure that our proprietary ECU upgrade offers incredible performance gains and rock solid daily driver reliability.

RENNtech tuning software for McLaren offers significant gains in horsepower and torque across the vehicle's entire power band. By modifying ignition timing and throttle mapping, optimizing air/ fuel ratios, increasing the engines rev limiter and modifying boost mapping for turbo charged vehicles, RENNtech performance software unleashes your McLaren's true potential.

TheÂ performance exhaustÂ for the McLaren MP4-12C is a high-tech system crafted from a special durable and heat-resistant titanium alloy with bigger tubes and unique solutions to improve torque and power at all rpms, especially in the most-used middle range. Our uncompromising approach uses theÂ best materialsÂ and design. Light systems save weight and lower the center of gravity, leading to better handling as well. AÂ special coatingÂ guarantees a state-of-the-art look. The 12C with the Akrapovič Slip-On exhaust system sounds deeper in the low rpms and serves up a delicious racing sound as the revs get higher. Slip-On systems contain specialÂ sound solutionsÂ to tune the sound frequencies: every element of the system was designed for maximum sound output, and offers everything needed for pleasant cabin comfort and to make the V8 sing out for true car enthusiasts at all rpms in all gears. On top of all this, the carbon fibre tailpipes create the strikingÂ visual impressionÂ that this is no ordinary McLaren.
