Dyno Jet PowerCommander V PCV FITS: 2015-2018 Yamaha R3; Part # 22-072. The Dyno Jet Power Commander PCV is a fuel injection adjustment unit that plugs "inline" with the bikes' stock ECU. The DynoJet Power Commander PCV uses original equipment style connectors so that no splicing or cutting of the harness is required. Most installations take less than 15 minutes, some as little as 5 minutes. Changes are made to the bikes fuel and ignition curves via the Dyno Jet Power Commander's onboard microprocessor. Using this technology they are able to offer a large area of adjustment without making any permanent changes to the bikes' ECU (electronic control unit). Removing the Power Commander PCV returns the bike to its previous stock condition. The DynoJet Power Commander PCV also comes complete with a cable link that allows you to change between different maps or make adjustments to a map file.
