Vortex Ignitions ECU programmable + fuel injection for Yamaha YZ250F 2019
The Vortex Ignition ECU Yamaha YZ250F 2019 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 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 and programming kit are optional) 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.
Note 1: As with all Vortex products we offer a 12 month manufacturing defect warranty.
Note 2: The ECU does not come standard with a handlebar switch as this is an optional extra. There is no need for a switch eliminator when not running the handlebar switch as with our other CDI products.
-Pre Programmed with 10 Performance Fuel & Ignition maps developed on the Dyno & Track - all the work is done for you!
-Instant Plug in Performance (replaces standard ECU with no mods to wiring required)
-Additional 3 fuel trim switches to adjust fuel mapping by +12.5% to minus 10% in Lo , Mid and Hi throttle openning
-Adjustments made using a screwdriver and switches provide visual feedback as to changes made
-Rubber Mounting Boot + Brackets supplied (where required)
-V-Boost - Programmable Voltage Boost Circuit for maximising Spark Energy across the entire rev range
-Higher Rev Limit (where required)
-Robust design -fully waterproof - o-ring sealed switches
-Diagnostic Flash codes - tests for sensor faults and flashes codes to a fault light
-Race Proven reliability
-Re Programmable (Software and Interface hardware not Included)
All Vortex products are factory programmed with Performance Fuel and Ignition Maps developed through extensive dyno and track testing by Vortex Ignitions Richard Muurling and tested with our network of technical support centres and race teams worldwide.
NOTE: This dyno graph is an indication only and is only measured at full throttle. The majority of gains are found at partial throttle settings where this bike is used most of the time by most riders.
It is also possible to connect the Vortex ECU with f.e. an AIM Solo 2 DL laptimer / datalogger through CAN bus. 38 channels (like RPM, throttle position, temperature etc.) will be logged in this way by the AIM datalog system.
