TO 12-VOLT SENSORS AUTHENTIC Magnum Digital Map Sensor Enhancer has been developed to engines installed with water4gas generators. Modifies MAP (Manifold Absolute Pressure) or MAF (Mass Air Flow) signal in fuel injected gas or diesel vehicles controlled by ECU. When installing an HHO electrolyzer more should be processed to achieve extreme MPG increases. After we inject hydrogen gas into the engine we need to reduce the fuel injection in the reason of economy enhancement. It will allow you to fine tune the fuel intake when applying HHO generator resulting perfect fuel savings, besides its 'in dash' design makes possible the adjustment while driving, testing. MAP sensor enhancer is not intended to be a fuel saver by itself but can warrant improvement of MPG if you use HHO electrolyzer. MAP is one of the sensors applied in an internal combustion engine's electronic control system. It provides instantaneous manifold pressure information to the ECU. This is necessary to calculate air density & determine the engine's air mass flow rate, which in turn is used to calculate the appropriate fuel flow. If you add hydrogen to the mix & really want to save fuel, you need to reduce the volume of original fuel. When you trick MAP sensor, the new fooled signal will tell the ECU not to deliver much fuel. Since the air/fuel ratio in injected up-to-date vehicles is regulated by the Electronic Control Unit (ECU) & most factory ECUs are set to maintain a 14.7:1 air/fuel ratio; this is known as a stoichiometric fuel mix, user is unable to trim manually or mechanically this ratio as by early models accordingly if you do not use MAP sensor enhancer you will not save much fuel despite this was the main reason you installed the H2O system for. * 10-YEAR MAGNUM FACTORY WARRANTY * Magnum Tuning has been dealing with manufacture of upgrades and fuel saver parts since 1994. Magnum's experience warrants peak performance, reliability & perfect style. Magnum Parts are made in EUROPE.
