Frequently Asked Questions - MAP/MAF Enhancer

Installation (2)

Here are some ways to obtain a wiring diagram(s) for your vehicle. I will tell you where you can get it free; but unfortunately, sometimes, you will need to purchase one if it is not available free.

Resource Price Note

Vehicle Manual

The signal wire is the wire on your MAP or MAF that has the lowest output voltage (usually between 0.5 volts to 3.5 volts).  It varies in voltage when the accelerator is depressed.

Do not confuse it with the incoming voltage (anything above 4.5 volts).

Please see videos below for visual instructions from other sources.


Setup (2)

During setup, please use extreme caution.  Setting the enhancer too "Lean" can stall your vehicle! We are not liable for any damages.

The HWY setting is optional.

The CITY and HWY settings is to allow the user to save 2 settings and be able to easily switch between the 2 presets.

Once you have found your optimal settings, you can leave the enhancer alone.

If you have a fuel injected car (usually cars made after 1990), then you need an either a MAP/MAF enhancer or an O2 EFIE; some cars will need both.  If you use an HHO Cell without these devices, you will most likely not see any gains - in fact, you may even decrease your MPG. 

About 60-70% of our customer feedback report that using a MAP enhancer is adequite to achieve increased MPG with an HHO Cell/Generator.  The rest reported needing additional enhancement (O2 EFIE). 

We suggest you first try a MAP enhancer for the following reasons:

If your car has a MAP (manifold absolute pressure) sensor, then our MAP/MAF enhancer is compatible with your vehicle.

If your car has a voltage based MAF (mass air-flow) sensor, then our MAP/MAF enhancer is compatible with your vehicle.  You know if your MAF is voltage based when the signal wire varies in voltage (0.5 - 3.5volts) when the engine is revved.
