Powered by Techlusion A brilliant invention by the father of electronic tuning for injection engines and a perfect optimisation instrument, enabling you easily to adjust the power development of your BMW yourself. Rich gains in performance and torque, smooth running and spontaneity of throttle response like you’ve never known are all guaranteed. The facts: Increased torque and performance across the whole RPM range (ca. 12% improvement in performance across the active ride range from 3000 to 7000/min). More spontaneous throttle response. Faster high-revving (12% faster than the original). Perfect, pre-set factory tuning. Easy to set performance across the whole RPM range. Adaptation to all conversions (blue air filter, exhaust systems etc.) and conditions takes less time. Quick reset to the factory setting. Impossible to make damaging adjustments or to use wrongly. Simple jack connection to wiring loom. No need to make changes to the motronics or wiring loom etc. Special “Wunderlich-Edition” for the European market. Completely waterproof and sturdy overall construction. Extremely small housing (84 x 50 x 10 mm). Comes complete with fitting kit and instructions. The factory setting (with series-production silencer, accumulator, header and air filter) already offers a hike in performance and torque and a perceptible boost to running (revs up significantly more softly and regularly). In combination with the Blue filter and/or sports silencer the PerformanceController is the key to optimum efficiency. Comes ready to fit. Warning: The Techlusion Performance should not be used in combination with any other chip tuning. Only for sports use!Here you will find a demonstration of the function of the Performance Controller.
