Welcome to our specialized BMW ECU and gearbox tuning services. Our expert team utilizes advanced techniques to enhance your BMW's performance, ensuring a smoother and more powerful driving experience.
ECU Tuning
Performance Optimization: By rewriting the software in your vehicle’s Engine Control Unit (ECU), we can significantly improve engine responsiveness and overall performance. This includes adjusting boost maps, ignition timing, and air-fuel ratios to deliver optimal power without compromising drivability.
Custom Mapping: Our custom-made flash tunes are engineered to provide the highest level of performance, tailored specifically to your BMW model. We modify throttle maps for better throttle response and raise the rev limiter for enhanced performance.
Safety and Reliability: We ensure that all modifications are within safe limits, considering factors like fuel quality and maintenance variations. Our goal is to unlock your engine's full potential while maintaining its longevity.
Gearbox Tuning
Enhanced Shift Times: Our gearbox tuning services focus on reducing shift times, making your BMW's automatic transmission more responsive and efficient. This results in smoother and faster gear changes, enhancing your driving experience.
Increased Torque Limits: We lift torque limiters to allow your engine to produce more power in every gear. This modification is particularly beneficial for those seeking improved acceleration and launch control.
Advanced Software Solutions: Using state-of-the-art tuning equipment, we develop custom software solutions for the BMW ZF8 and other automatic gearboxes. Our software is extensively tested to ensure reliability and performance.
