ThunderMax fuel injection system. This is a wide-band closed-loop self-tuning module for fuel-injected Harley-Davidson Touring and Trike models. It adjusts air and fuel automatically as temperature, altitude, or fuel quality changes. Works on stock motors or bikes with cams and exhaust. Throttle response is sharper, starting is easier, and the idle stays steady. It also sorts out popping and backfiring through the pipes. You will need 18mm bungs in your exhaust to accept the sensors. 2007 to 2009 models already have these bungs. Otherwise you will need to modify your existing pipes to accept them.
