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. Vortex has done extensive work to include tune parameters which improve starting and almost eliminate the flameouts experienced with some EFI MX bikes. This ECU is designed for closed course competition only.
