I spent some timing working on a couple different bikes with this aRacer Mini 5 ECU along with my testing and development with the big brother, the Super RC2 ECU, and the performance out of the box is staggering. This ECU performs just as well as my Race Spec ECU flash but also includes accelerator enrichment settings out of the box that completely eliminate the throttle hesitations often found in the stock ECU that we have spent SOOOO many hours on the dyno with different bikes trying to eliminate. Not to mention you get a fully programmable race ECU that is upgradable with the smoothest quickshifter I’ve ever used from aRacer and the most accurate MAP Pressure based autotuner available. This ECU is my new favorite for a plug and play solution for street riders and racers using a stock engine and full exhaust. Plus, if you make changes down the road, you can use the autotuner to update your tuning.
Some of the enhancements in this race ECU compared to the stock ECU are:
-Optimized fuel delivery
-Optimized fuel injector timing
-Optimized ignition timing
-Rev limit control
-Idle speed control
-Optimized accelerator enrichment
-Engine braking control
-Most accurate autotuner on the market
-Expandable with additional modules and sensors for quickshift and autotuning
Installing a race ECU could not be easier. Simply unplug the stock ECU, and plug in the aRacer Speedtek RC Mini 5 ECU to the stock connector. That’s it! Just be careful with the connector on the stock ECU, it has a special locking piece, so don’t force it. Even the additional aRacer Quickshifter plugs directly into the OEM O2 sensor connector (OEM O2 sensor is removed) and uses the stock wiring. Pretty awesome.
