KESS3 expands coverage with BENCH mode and direct access to the Keihin 38770-MKE ECU without opening the control unit, alongside the already available connections (OBD and BOOT – available on pre-2020 applications).
On these 250cc and 450cc configurations, which cover a large portion of today’s racing market, it is possible to precisely work on fuel management and engine strategies, optimizing performance.
