EVOMSitECU Tuning for 997.2 GT3 RS

Views

Product Description

Dyno tuned and tested on the Shark Werks 2011 997GT3 RS development car. EVOMSit software will add 16 RWHP and 13 ft-lb torque to the wheels. Left foot braking is enabled and a better throttle response attained.

Dyno Test:

Top to bottom shown are:

  • EVOMSit Software with Shark Werks Exhaust
  • SharkWerks Exhaust only
  • Factory stock 2011 GT3RS

    The tuning involves a more aggressive fuel map, timing advance optimization for specific grades of fuel, and a more responsive accelerator pedal. 

    A summary:
    With software calibrated our 2010 GT3 RS went from 424 RWHP to 440 RWHP at the peak. The car gained about this much horsepower for most of its RPM range.

    The car gained over 13 ft-lb of torque at its peak around 6600 RPM and more torque throughout the RPM range.

Features:
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.

Press Coverage

Particularly impressive is the EVOMSit software tuning. Partial-throttle response, often a weak spot with aftermarket tunes, is every bit as good as a factory GT3’s. It’s the final piece in that rarest of puzzles: an aftermarket engine that outshines its factory basis.
