HHO Cell Wiring Diagram with EFIE and PWM

Since it took me so long to find information on this I figured I could help save some people some time and make this info available to them more quickly.  As I have researched for ways to wire this for my truck I came across AlmostHydrogen on youtube.  He has found an easy way to relay this info through a picture diagram.  He explains everything you will need as far as wire, tools, etc.  The most important reason why people's HHO Cells don't seem to work at increasing mileage is because of this right here.  They do no wire everything correctly or have the right parts.  They may even forget to put something in the system.  So as far as I know this  is one of the most accurate diagrams I have found.  He has other videos of wiring these HHO Cells, but the video I posted below is the one I have found to be the best. This video does not include wiring for a MAP/MAF Enhancer. I am still looking for a video on the wiring for that.  But it is probably safe to say that you would just switch out the EFIE for that.  Please enjoy and be safe!

PWM - Pulse Width Modulator - is a commonly used technique for controlling power to inertial electrical devices, made practical by modern electronic power switches

Does Adding an HHO Cell Generator to Your Car Increase Fuel Mileage?

If you do a Google search or a Youtube search for "HHO CELL INCREASE MPG" I can almost guarantee that more than half of the results you get will be about how it isn't true, it will ruin your car, Mythbusters busted it, it doesn't increase fuel economy, etc., etc. But to tell you the truth, you need more than just hooking up a HHO Cell to your air intake to increase your mileage.  It requires a few for steps than that.  It still is quite easy, but there a few extra very important things that need to be added to your system to make your car recognize the HHO gas and use it efficiently.  In just about every modern car after, maybe, the late 60s has an O2 sensor of some sort in the engine.  The O2 sensor calculates how much O2 is inside the engine opposed to how much is outside the engine.  This then creates a voltage in the sensor between 0 and 1 volts.  The computer in the car takes this reading and will decide whether to add more gasoline to the combustion chamber or use less.  The optimal voltage is .5 volts. When you add an HHO Cell to the air intake the amount of oxygen inside the engine rises which tells the computer to add more gasoline to counteract it.  This is why people think the HHO Cell can not work at increasing fuel economy. But, there is a nifty little device they have out now called an EFIE.  An EFIE is connected to the computer and O2 sensor and can be calibrated to change the reading from the O2 sensor to trick the computer to thinking the same amount of oxygen is in the air intake.  This will make the engine use the hydrogen more efficiently and therefore give you better gas mileage. Depending on what year your car was made and what make it is, you may need to use a MAP/MAF Enhancer instead of an EFIE to achieve the same results.
