Onboard adjustable fuel controller for Yamaha C3 that will allow you to tune your C3 without any tools or computer! Get 15% more or less fuel with a push of a button!
The Feign Fuel Controller will allow you to tune each RPM parameter in 500rpm increments. It will also allow you to set rev-limits (as well as remove the rev-limiter with a switch of the button), store 2 preset tunes, and will allow you to tune in live mode. Highly recommended for those who are looking forward to big boring their C3 engines.
The Feign Adjustable Fuel Controler could be used as a rev-limiter remover as well! Simply install the unit and change where you would like to limit the RPM at or switch the toggle switch and run with no rev-limiter!
