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
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.
