This is great for people who don’t want a fuel controller, but want to run optimized fuel maps as they upgrade their bikes. you only pay the shipping to get your flash updated). The best part: 2 Wheel Dynoworks offer unlimited reflashes (i.e. Flash performance tunes via OEM diagnostic connector, no need to remove and send out ECU Display vehicle data channels in real-time Weather resistant for use. Besides disabling the stock O2 sensor, they can also remove VMAX, increase the rev limit, and load optimized fuel maps for many popular exhaust and air filter combos.

This can give more aggressive throttle control and some timing advancement and allow you to Auto-tune all ranges of the motor since the stock ECU is open-loop throughout the entire rev-range. Many owners prefer to disable the stock O2 sensor entirely by reflashing the ECU. The supplied O2 Optimizer does work well, even when adding Auto-tune, but you can only “Auto-tune” in the open-loop range of the stock ECU. To quote Chris Kelly from Dynojet research: Reflashing your ECU also allows you to unplug the stock O2 sensor (and potentially replace it with a wide-band one as shipped with the PCV or Z-Fi) without the ECU defaulting to a base map with poor AFR. With cooler fan temp settings, reduced engine braking, and unrestricting other factory settings, youll experience smoother drivability, and more power. The reason for this is called ‘closed loop’, a restriction of the stock ECU preventing any fuel controller from making adjustments to the air fuel ratio (AFR) below 6k rpm.
