ECU Technical data
Thanks to a simple USB cable, it's now extremely easy to connect your new JD ECU to a computer.
All JD ECUs come with a USB cable and the Sensor Reader software included, which you can use to show in real-time (even when the engine's off) a set of parameters managed by the ECU box, including: pressure and TPS values, air and water temperatures.
The ECU box has two independet maps, the rider can switch between them at any moment, thanks to the switch control placed on the handle bar.
Traction control and shifter functions are available for some motard-specific models.
All JD's ECUs use the same connector as their stock counterparts.
Depending from the model, the internal CPU analizes several variables such as pick-up inputs, actual engine RPM, trottle position and the gear position.
Our ECU Unit analize all data acquired in real time to provide the right ignition spark, according with memorized data. The CPU can make a control feed-back operation at every engine revolution, for better accuracy and performance. The power map can be examinated from 1.850 to unlimited RPM: for values under 1.850 RPM the ignition spark starts at the end of the pick-up sector (near the PMS).
The pick-up position can be set from 90° before PMS since to 2° from the maximum ignition advance. If your carburettor has the TPS and/or the Power-jet, our electronic ignitions can manage these functions: Power-jet can be set as closure or as release in a range from 1.900 to unlimited RPM, with a solution of 50 RPM. It's also possible cutting out the power-jet function using included software or setting an hysteresis range to avoid any Power-Jet flutter effetcs.
With our software you can manage up to 32 active point to define your best curve. Define a specific curve for each of 8 throttle position: the internal CPU will interpolate data in real-time for intermediate trottle positions. Define a set of curve for each gear you use. Set different Power jets parameters for each curve.
The internal CPU also supports a RPM limit-switch: the start of this function may be set in a range from 5.000 to 20.000 RPM. All JD's ECU units mounted AUTOMOTIVE components: we tested our units at 120°C (248 °F)
Our ECUs are shipped with a standard power map: you can personalize it with the help of your reseller or do it by yourself, buying the related software.
We recommend you to modify standard curve only if you have techical expertise or support available, to prevent any damage on your engine.
Before you modify the maps of your ECU, please carefully read the manual.
