Muzzys has the perfect package for any Can Am Commander owner who wants the ultimate tuning solution. The basic auto adjust package includes the Wego 3D dual channel Air Fuel Reader, one Bosch oxygen sensor, and the amazing new Digi-Tune PRO that's pre-programmed to auto adjust the air/fuel ratio with constant input from the Wego 3D's 0-5 volt output. With the addition of the dual air/fuel ratio gauge and an extra oxygen sensor, real time monitoring of the front and rear cylinders is possible. NOTE: Oxygen sensor bungs must be installed on the exhaust head pipes. These are standard on all Muzzy Commander Exhaust Systems.
