CDI variable speed forward Derbi euro 4 >2018 Malossi

Variable timing advanceCDI from Malossi for Derbi D50B0 engines with Euro 4 standard.

Malossi has made several improvements to the power curve and most importantly increased the RPM limit to 15.000. The Digitronic CDI manages the ignition timing advance and the SAS valve.

Ignition advance map

The ignition advance is managed by a three-dimensional map by linear interpolation, which contains 16 parameterisation points for the rpms and 8 parameterisation points for the engine temperature.

SAS valve performance map

The secondary intake valve on the injection body allows the engine management to compensate for the non-linearity typical of a carburettor-fed engine.
The SAS (Secondary Air Source) valve is managed by the ECU via a linear interpolation performance map containing 16 parameterisation points for RPMs and 8 for engine temperature.
The SAS valve reduces emissions and optimises engine performance for all operating conditions.

Plug & play, compatible with original sensors and actuators.
Calibrations and fine-tuned drawings allow a concrete increase in engine performance.

• Feed rate control
• RPMlimiter: 15.000 RPM

BIKE IN ORIGINAL CONFIGURATIONS recommends the use of Malossi sport exhausts to the fiit is necessary to replace the main jet max the maximum main gum from 68 to 75 by eliminating also the intake diaphragm present in the carburettor.
The correct ratio correct ratio of the transmission: pinion Z13, sprocket Z52 (original Z11/59).
