The 10 Map ECU is like our 10 Map Ignition and EFI Interceptor rolled into one module controlling not only ignition timing and Voltage output but also fuel mapping 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 & Ignition 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 & 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 & graphing of many parameters (when combined with the ECU Software - not included)
The 10 Map ECU provides substantial gains in the POWER settings but also and in particular for the 350SXF the off road riders will love the TRACTION and LINEAR POWER settings. Used in conjunction with the Handlebar Switch the KTM350SXF make a fantastic OFF ROAD machine as well. For the 250SXF we have developed performance maps for modified and stock motors that are pre programmed in the ECU. The KTM250SXF and KTM350SXF will benefit from:

Improved bottom end Power and throttle response
Improved top end and over rev Power
Better starting and stall prevention
Higher Rev Limits
Fuel timing for improved atomization and response

Pre Programmed with 10 Performance Fuel & Ignition maps - all the work is done for you!
Instant Plug in Performance (replaces standard ECU with no mods to wiring required)
