Premium ECU Tuning
Severn Tuning provides a wide range of aftermarket performance upgrades not typically available to enthusiasts, including specialized ECU tuning. Each ECU tune is individually developed by a licensed professional engineer.
Proven on the Race Track
Our full product line is designed for endurance in the most demanding environments. Our customers eagerly embrace tough conditions, and this is where Severn Tuning reliability thrives. We are proud to be the official tuning sponsor of the Bimmer Challenge race series.
Fuel System Upgrades
Great ECU tunes start with quality hardware, and fuel injectors are some of the most critical components of any vehicle. Severn Tuning recommend Fuel Injector Clinic (FIC) fuel injectors in our tuning applications whenever possible. We are a preferred dealer and can enhance naturally aspirated, forced induction, or alternative fuel setups with our high-end FIC injectors.

The FIC Advantage
Simply put, if we know exactly how much fuel an individual injector will spray in a given amount of time, we can calibrate the ECU to compensate so that each cylinder gets the precise amount of fuel needed. We do this by modifying each individual cylinder’s injector pulse width through what is known as ChronoBalance: matching ECU software to measured individual injector performance. We recognize that a lean condition in a single cylinder can cause total engine failure. Conversely, an overly rich mixture will result in sub-optimal performance and can fatigue components over time. For these reasons, we ChronoBalance all ECU tunes where injector data is available. FIC provide us with the most accurate and in-depth injector data based on actual testing of each injector produced.
