what do i set this device to before i run a data log?


  • The JMS FuelMAX - Fuel Pump Voltage Booster V2 should be set up once when your car is professionally tuned. That setting should be left as it is for any type of data logging.

    The Fuel Pump Boost I Needed!!

    Due to the installation of my new supercharger, my car was starting to lean out on the top end. I didn't want to pay for a new fuel pump and the labor to install it. (Even though I probably could have just installed a fuel pump myself.) So I selected this fuel pump voltage since it appeared to be a quick and easy install, and easy to dial in. The install really was easy! IT SHOULD BE NOTED THAT THIS UNIT WILL NOT PLUG DIRECTLY INTO THE GAS PEDAL FOR THE 2005-2010 MUSTANGS AS IT IS ADVERTISED! (I had consulted directly with the manufacturer about this.) You can call the manufacturer for a free Hobbs Pressure Switch to be sent to you, but I installed it instead by splicing one wire directly to the TPS wiring at the throttle body. (This setup really is the same as plugging it into the gas pedal.) I currently have this unit set at only 50 boost activated at half throttle and have plenty of consistent fuel delivery at the top end. I personally think this unit is a little pricey, but it is fair to say that its is in the same realm of costs for other fuel delivery upgrade options.
