The Vortex ECU for the YAMAHA YFZ450R is like our CDI and EFI Interceptor rolled into one module. The ECU controls not only Spark timing and Voltage output but also Fuel Metering and other engine management functions. The result is more power, better power, easier starting and ultimately faster lap times. This unit comes pre-programmed with 10 Performance Fuel & Spark timing maps as well as having 3 additional switches for user trimming (adjusting) 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 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-available at additional cost) with parameters that are far more extensive than those found in any factory setting tools, such as Rev Limits, Throttle Enrichment & Decay time, Fuel timing, High Resolution Mapping, Dwell Timing, Voltage Output and trim tables for cold starting, air intake, baro, battery voltage , etc... In addition there is real time logging & graphing of many parameters. The ECU connects to a PC through our USB/Power adaptor which requires no external power source.
