Allows nine easy-to-program adjustment points for both the fuel and ignition maps. Monitor function allows user to monitor the data from various sensors on the bike as well as adjust idle timing, see engine running time, and self-diagnosis function. Powered by two AA batteries, thus no laptop or time consuming downloads necessary. Unit does not have to be plugged into bike to create maps. Compact design can fit in the palm of your hand, pocket, etc. Memory function can save up to nine custom maps. I have a couple of spare, new units available. Hence the multiple package types shown. I may have some used ones as well. Ping me if those interest you.
