This Power-Up Cable is used with an external 12 volt battery to provide power to the ECU and Fuel Pump of the CFI system.  This makes it possible to check and adjust the Throttle Position Sensor (TPS) alignment between the Power Commander and the stock ECU without the engine running.  It also powers up the optional DynoJet LCD Display, which is quite handy when using this display as a tuning aid.  And, it is extremely beneficial in repressurizing the fuel system if fuel pressure has ever been blown off, most commonly done when changing the fuel filter or performaing other fuel system service work.  Rather than being forced to crank the engine over multiple times by hand with the recoild to re-pressurize the fuel system, simply connect this Power-Up Cable to initialize the fuel pump.  Then pull the rope a couple of times and the engine will fire up as it normally does.
