This unit comes pre-programmed with 10 Performance Fuel and Spark timing maps as well as having 3 additional switches for user trimming of Fuel in Lo, Mid and Hi throttle openings.
The ECU plugs directly into the bikes standard wiring harness and interfaces with all the standard engine sensors such as ECT (Engine Coolant Temperature), IAT (Intake Air Temperature), MAP (Manifold Absolute Pressure), TPS (Throttle Position Sensor), CPS (Crank Position Sensor) to adjust fuel and spark timing for optimum power delivery in all weather, altitude and load conditions.
Performance gains vary depending on Throttle and RPM points however typically gains are in Top End power and Bottom End throttle response is expected from the "Power" settings and a smoother more tractable or rideable power from the "Traction" settings.
We have done extensive work to include tune parameters which improve starting and almost eliminate the flameouts experienced with some EFI MX bikes. All of the development work is done for you! All that is left is for you to do is chose a setting that best suits your riding style or track conditions and ride!
The ECU is also fully programmable (Software not supplied) with parameters that are far more extensive than those found in any factory setting tools, such as Rev Limits, Throttle Enrichment and Decay time, Fuel timing, High Resolution Mapping, Dwell Time, Voltage Output and trim tables for cold starting, air intake temperature (IAT), Engine Coolant Temperature (ECT), Barometric Pressure, Battery voltage, etc…
In addition there is real time logging and graphing of many parameters (when combined with the ECU Software - not included)
All Vortex products are factory programmed with Performance Fuel and Ignition Maps developed through extensive dyno and track testing by Vortex Ignitions engineers with our network of race teams worldwide.
