EVOMSitECU Tuning for 997.2 Carrera / S / GTS


Product Description

In a collaborative effort with Evolution Motorsports our in-house 2009 997S PDK vehicle was utilized to help develop, test and fine tune the EVOMSit performance software (the first of its kind for the new 2009 A91 engine and direct injection based cars). As with all EVOMSit performance software it comes with integrated advanced (SP) sport pedal and IST (integrated switching technology) settings to maximize throttle response and higher octane timing maps. We are now pleased to offer what we feel to be an extremely robust solution for those of you with 2009+ 997 based cars in the form of the EVOMSit. With the EVOMSit software a typical 997S PDK car can expect to gain ~13HP and 12TQ on 91 octane.

The EVOMSit TUNEit handheld unit is included with your ECU Tuning purchase. This unit allows you to download and install our performance software via your car's OBDII diagnostic port. Simply plug in the handheld unit via included OBDII cable, read out your file, and email it to us. (Access to an email-enabled PC with Windows operating system and USB port is done via the included USB cable.) We will email you back (usually within 24 hours) a performance file that you can upload yourself.

NOTE: Installation requires the use of an automobile BATTERY CHARGER (10+ AMP)

EVOMSit Run 1: EVOMSit V4 Software HP and TQ (Solid Lines)
Baseline Run 2: Baseline - Stock Software HP and TQ (Dashed Lines)

Power is measured at 4 wheels on an independent Mustang 500 SE AWD dyno in a controlled environment for accuracy. Dyno runs shown are the average runs of a 10 run sample group for both the Baseline and EVOMSit modified runs. Dyno runs are accurately run with the same RPM start point, same transmission gear, same octane fuel and same cool down time in-between runs. Measurement was made with 1 x 65,000 CFM main cooling fan in the front of the vehicle with 2 x 5000 CFM "spot" cooling fans to extract exhaust fumes from the exhaust. Dyno room temperature was 64.2 degrees Fahrenheit for both sets of run groups and fuel grade was 100% pump 91 octane CA grade oxygenated fuel.

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 that are progressively staged and we modify them to our performance specifications, 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 make any physical changes. IST is far more intelligent than any manual switcher found on the market. The use of manual switchers can cause serious engine damage if accidentally switched to a “race mode” without having adequate octane levels 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 arise. 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 in 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.
