2008 Kawasaki Zx-10rHard Parts
Stronger, Faster, SmarterElectronics First off, the Kawasaki Ignition Management System (KIMS) that debuts on the ZX-10R is not traction control. While KIMS will negate unwanted wheelspin in extreme situations, such tendencies are incidental to its real purpose, which is to protect the catalytic converters from the increased exhaust-gas temperatures that accompany sudden spikes in engine rpm. Upcoming Euro 4 emissions standards reportedly will include an endurance test for catalytic converters; consider KIMS a preemptive strike. As for how it works, KIMS is a wildly complex electronic system that monitors engine speed, throttle position, vehicle speed, gear position, intake air temperature, intake air pressure, engine temperature, exhaust-gas oxygen content and more. Sampling occurs every .02 second and, when the ECU senses a change in engine speed that runs contrary to other factors (e.g., rpm rises without a corresponding change in throttle position), ignition timing is retarded according to one of 500 (!) pre-programmed ignition maps. Caveat: KIMS does have legitimate traction-control properties if paired with the factory race-kit ECU.
