Evolution MotorSports launches its EVOMSit Performance Engine Software and EVT640 Performance System for the new 997 GT2. The EVOMSit intelligent ECU Tuning, combined with EVOMS VTG Headers, Cargraphic 200 Cell Catalyst Pipes and EVOMS BRV's completes our potent performance system that produces a safe and effective performance gain from the 997 GT2 with bolt on components. Our EVT640 system replaces the restrictive ceramic catalysts with a more efficient 200 cell HJS metal substrate catalysts. Additionally, the restrictive OEM headers are replaced with our hand built VTG headers with pyramid merge collectors. The EVOMS headers have been engineered with the proper length and diameter primary tubes to match the flow and output of the modified GT2 engine. They are then ceramic coated to help keep the heat inside the tubes which helps with exhaust velocity and improved overall efficiency.EVT 640 Includes:
-EVOMSit 997 GT2 ECU Tuning
-EVOMS Boost Recirculation Valves (Pair)
-Cargraphic 200 Cell Catalytic Converters
-EVOMS VTG Performance Headers

HP Output: 640
TQ Output: 646

IST (Intelligent Switching Technology):
IST is an OEM feature that is built into the factory ECU and allows for automatic switching of ignition timing maps based upon input received from other engine sensors. Available for certain EVOMSit performance programs, the EVOMSit IST programming incorporates this intelligence for true and safe flexible power without compromise. The EVOMSit ECU tuning utilizes the multiple OEM ignition tables in progressive stages, which can optimize safe performance based upon outside conditions and different octane fuels. The ECU automatically switches to the best-suited ignition map creating an automatic “race mode” if race fuel is utilized. This IST function is always active and will switch automatically without having to physically change anything. IST is far more intelligent than any manual switcher found in the market. The use of manual switchers can cause serious engine damage if accidentally switched to a “race mode” without having race fuel in the car. This manual type of switching technology physically locks the timing map and can over ride the ECU’s ability to protect itself if unfavorable conditions exist. This manual switching is archaic considering that OEM ECU has the ability to analyze conditions and switch timing maps automatically. EVOMSit with IST is the intelligent way to utilize ECU timing map switching.
SP (Sport Pedal):
All E-Gas (drive by wire) cars from model year 2000 and newer have an electronic throttle valve, which is controlled by the cars ECU. Available for certain EVOMSit performance programs, EVOMSit Sport Pedal™ (SP) feature changes the ratio of accelerator pedal movement verses opening of the throttle valve which will increase throttle response. By modifying these maps in the ECU calibration, throttle response is drastically improved and the “throttle delay” which is a common complaint among enthusiasts is eliminated. Certain cars contain an OEM “sport mode” which incorporates this same Sport Pedal™ feature. For these cars, we incorporate the OEM “sport mode” pedal calibration for the regular mode and further increase the responsiveness of the “sport mode” with our improved calibration.
