Like new aRacer ecu for crf110. I also have a tbparts mount I can include at full asking price ($40 from tbparts) that is brand new still in the packaging. ECU works as it should. Was only installed for a few hours and parted the bike out. This ECU gives you the ability to tune every aspect of the bike from rpm limiter, fuel mapping, ignition timing, and lots of other things. You can also purchase the autotune and the ecm will correct fuel values on its own (not included) This is a must have for full mod bike! Good luck finding a better deal than this.
