Dynojet Power Commander VUsing valuable knowledge learned from the Power Commander III, Dynojet introduces the more capable Power Commander V, a premier EFI tuning system. Retaining the famed user-friendliness of the III, the V features a smaller and more refined package and the ability to not only tune the fuel injection, but also the ignition timing giving you unparalleled access to performance enhancing possibilities for your bike. From simple corrections of off idle hiccups to extensive race level mods, the Dynojet Power Commander V is one of the best tuners out there.
