New MAP Sensor Enhancer with dual adjustments for your hydrogen powered vehicle. These are a must have if you are using an HHO Generator Setup. This is the Ultimate HHO add on, allowing you to have full control over your air/fuel mixture on any fuel injected engine. The gas mileage benefits are not seen without this device, on 1996 or newer vehicles. If your efficiency gains reduced after a few days or weeks, or did not appear at all, it is likely that the vehicle computer has adjusted and you need to install one of these devices.

This unit will allow you to gain full control of your MAP Sensor allowing you to lean out your air to fuel mixture to Improve Your Gas Mileage. Separate CITY and HIWAY controls allows the operator the ability to set the MAP Sensor Enhancer for low speeds under 40 MPH and for higher speeds for optimal performance. Once you have it set there is no further tuning necessary. The FACTORY / ENHANCED switch allows the operator to quickly return to factory default settings easily and immediately.

Does my Vehicle require a MAP Sensor Enhancer?
A MAP Sensor Enhancer is required for most vehicles that are newer than 1995, due to the electronic oxygen sensor systems. Diesels do not need MAP’s because they do not use 02 sensors. MAP’s will not work for some vehicles which have AFR or wide band 02 sensors.

How does the MAP Sensor Enhancer work?
The Manifold Absolute Pressure (MAP) sensor signal is electrically used in a similar way to the use of Mass Air Flow (MAF) sensor signal. It takes a 5 volt signal from a computer called the ECM or ECU (Environmental Control Unit or Module), and returns a lower direct current signal in accordance with the vacuum in the engine. A higher output voltage means lower engine vacuum, which is then calculated as “more fuel is needed”. Lower output signal indicates higher engine vacuum, which requires less fuel. It's not just fuel control. The MAP sensor signal gives the computer a dynamic indication of engine load. The computer then uses this data to control not only fuel injection, but also gear shift and cylinder ignition timing.

Will the Enhancer work with a MAF – Mass Air Flow Sensor?
If the sensor operates by varying a voltage to the ECM, it should work unless the MAF Sensor is frequency varied. The Air Flow Sensor or Mass Airflow Sensor is one of the components of an electronic fuel injection system and is found in many modern vehicles. The MAF sensor is usually installed inside the intake air duct between the air filter and the engine. The MAF sensor is used to measure the amount of air entering the engine. This measurement is used by the engine computer or ECM to calculate the proper amount of fuel to be injected into the cylinders in order to provide optimum combustion and low emissions. If you MAF Sensor is voltage varied, incorporate the MAP Sensor Enhancer to reduce voltage to the ECM.

Installation should take less then 15 minutes and instructions are included. Wire colors may vary from vehicle to vehicle. This device is experimental and we cannot assume any responsibility for improper installation or miss use. Will not work on cars with a pulsed frequency MAP/MAF signal or wide band O2 sensor... Please check with your mechanic to make sure this will work for you in your particular vehicle.
