A piezoelectric shift sensor sampled up to 1,000 times a second feeds the ECU directly, so the ignition cut is timed by the ECU rather than a dumb switch: clutchless upshifts that are faster, more consistent and closed-loop corrected. On ride-by-wire bikes it can also handle downshift blipping. Developed and proven in Asia Road Racing Championship competition.\u003c\/p\u003e\u003cp\u003eThis is an ECU expansion kit, not a standalone shifter — it only works with a supported aRacer Super X \/ Super XX ECU.
