Kit including the Rapid Bike Evo module and the USB cable and model specific wiring harness .
The Evo module manages up to 8 injectors and modulates the signal up to two O2 sensors (up to 2 lambdas). The purpose of the O2 sensor (lambda) modulation is to prevent the stock ECU from recognizing the adjustment applied by the RapidBike module to the injection map without any further attempts to re-set the stock parameters matching the criteria fixed by the restrictive exhaust gas emission laws.
When riding the motorcycle, the self-adaptive feature determines the automatic self-correction of the air/fuel ratio maps: this active management is added up to the pre-set parameters. The adjustments set by Rapid Bike EVO improve the engine efficiency in order to reach the best performance.The self-correction process is set in multipoint technology according to RPM and TPS, for the whole range of the engine working, even when the original RPM limiter is raised (when available).
Modulating the stock O2 sensor (lambda) signal is a technology far more advanced than the so called “O2 sensor eliminator” (or any other similar device used by the competitors) since they send a static/constant signal which is in conflict with the typical behavior of the lambda sensors, therefore causing the main ECU to perceive such a constant signal as a mistake to be corrected. Thanks to Rapid Bike exclusive technology for the modulation of the stock lambda signal the main ECU considers this behavior as standard, therefore it will not try to re-set the stock engine parameters.
The Evo module is universal (same as RACE module) , this means that it can be installed on all the motorcycle models listed in the applications list (once it is properly programmed using the professional software Rapid Bike Master PRO (sold only to dealers/tuners).
The Evo module’ s most important benefit is the so-called Auto-adaptive feature, that is the ability to correct automatically the injection map adjustment by reading the signal of the stock O2 sensor (lambda) while riding the bike.
Almost all Ducati Race or Evo systems control both O2 sensors which provides individual cylinder mapping and adaptive fuel injection tuning.
