This fuel injection module is just (3-1/4"/83mm wide x 2-1/4"/57mm high) and works in conjunction with the stock ECU unit. No need for permanent changes. It will make the fuel system and the ignition fully programmable. During cold start-up the Power Commander can read the exact engine temperature through the bike's own ECU, which allows the tuner to choose how much fuel to add for a given engine temperature. Big Inch modified bikes should be easier to start than ever. With a universal on/on toggle switch, or the Dynojet PCV MAP switch, it is now possible to switch between two fuel/timing maps, like for economical touring and racing or high octane and low octane fuel. The Gear/Speed input allows maps adjustments based on gear. The Analog input allows the tuner to install any 0-5 volt sensor and build an adjustment table based on its input such as boost or temperature. The Power Commander can be tuned on a PC with an USB cable connection, no extra power supply is required. Complete with software for tuning but ready made maps can be downloaded if preferred. **Dynojet product not available to purchase by Dealers located in the UK**
