EVOMSit is fanatically obsessed with achieving ultimate perfection with our performance engine software. Ouranalytical tuning methods combined with methodical testing procedures, state of the art equipment and unmatched mechanical intelligence are fused together to create the ULTIMATE aftermarket performance software.A critical and fundamental aspect of software development and tuning stems from a complete hands on mechanical understanding of the latest generation high performance Porsche engines. This is the foundation of EVOMS and there are no other US based aftermarket performance companies that have more experience and has built more engines than Evolution MotorSports. We have practically reengineered the entire Porsche flat 6 engine. The combination of our extreme testing and tuning measures coupled with our immense mechanical knowledge and engine building skills clearly sets EVOMSit as a true leader in all aspects of engine tuning and engine development.EVOMSit software is custom-made for each customer to match their specific needs and vehicle upgrades. For each vehicle platform we tune, we take the time to thoroughly develop software specifically matched to different stages of hardware upgrades and fuel octane levels. This development is carried out on the dyno and on the street to ensure maximum reliable performance and smooth drivability. When installing EVOMSit software on a vehicle the customer fills out an expansive questionnaire that covers modifications, fuel quality, and the expected type of use of the vehicle. This information is used to create a tune that not only matches the physical parameters of the car being tuned, but also caters to the driver's needs. For example, a street-driven car may benefit from very aggressive throttle response and the maximum power possible on pump fuel. A track car may require very linear throttle response for maximum control while driving on the limit, or a higher rev limiter to extend the powerband on medium length straightaways.For installation, visit an EVOMSit flashing partner worldwide, or do it yourself using our TUNEit Gen 2 OBDII flashing tool.
