Technical data

ECUs

Our ECUs analize all data in real time to provide the right ignition spark, according with programmed profiles.

For better accuracy and performance the CPU executes a feedback control operation at every engine revolution.

The power map can be examined 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 up to 2° from the maximum ignition advance. If your carburettor has the TPS and/or the Power-jet, our products can manage these functions.

Power-jet can be set as closed or released in a range from 1.900 to unlimited RPM, with a resolution of 50 RPM.

The power-jet function can also be excluded setting an hysteresis range to avoid any Power-Jet flutter effects.

 

The control units also support a RPM limit-switch: the start of this function may be set in a range between 5.000 and 20.000 RPM.

JD Racing ECUs are built with automotive components rated at 120°C (248 °F) and use the same connector as their stock counterparts. They feature two indepedent maps: the rider can switch between them at any time, using a switch placed on the handle bar.

PROGRAMMING KIT

Thanks to a simple USB cable, it's now extremely easy to connect your new JD ECU to a computer.
Our programming kit includes a USB cable, the ECU programming software and the Sensor Reader program. Sensor Reader allows you to monitor in real-time (even when the engine is off) a set of parameters managed by the ECU, including: pressure and TPS values, air and water temperatures.

THE SOFTWARE

With our software you can manage up to 32 active point to define your best curve. You can define a specific curve for of 8 throttle positions: the internal CPU will interpolate data in real-time for the intermediate ones.

You can also define a curve for each gear you use and for each curve different Power jets parameters.

INSTALLATION

Our ECUs are shipped with standard power maps: you can customize them with the help of one of our resellers, or do it yourself by using the programming kit.

 

We recommend you to edit the 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 read carefully the manual.
