Tiny Map Enhancer
This is the smallest, most affordable MAP / MAF Enhancer you will find anywhere online!!
Great for surface mount installation! Why have a huge box???
The Tiny Map is a full featured controller to give you full control of your vehicles MAF/MAP sensor!
If you already built your Water4Gas device or hydrogen generator then you need the Tiny Map!
The Tiny Map is a must have on todays fuel injected cars if you are running anykind of hydrogen generator or HHO system. When your hydrogen system improves the quality of the combustion, your oxygen sensor will see a lot more oxygen and begin sending a command to RUN VERY RICH. When that happens you may not even see any mileage increase due to you cars computer fighting against you. The Tiny Map is the easiest way to correct this in many vehicles without messing with the o2 sensor!
By adjusting the MAF/MAP enhancer knob you can lean out your engine to compensate and reduce the gas being sent to your injectors. Our MAP/MAF sensor enhancers are very powerful and simply cannot be beat. You will have the ability to lean your vehicle out to the point of stalling…that is a lot of control. For that reason this device should never be used withou some for of alternative fuel like hydrogen, propane or water injection.
The MAP/MAF enhancer is very important for fine tuning your hydrogen system fuel savings. You can adjust it full left to be in completely stock mode for climbing hills and towing, then just dial the MAP/MAF knob back to the right to lean it out for the highway. Dial your mileage to where ever suits your needs at the moment. Make sure you watch the video below!
Actual knob colors vary depending on supplies on hand

Just like all the big dual edge map sensor enhancers, our Mini Map Enhancer give you full control over how lean your engine is running all in a SMALL easy to mount package. FULL control… TINY size… GREAT price! Gotta LOVE it!
Why only one knob when every one else uses 2?
Simplicity! In our real world research, we have found that you constantly have to fine tune the MAP/MAP enhancer from one tank of fuel to the next. Different conditions may need slightly differnet adjustments. With 2 knobs that just means twice the tuning! With our very simple Tiny Map Enhancer you just adjust it as you need it! Need full power? Turn in all the way to the left… on the highway it is simple to lean it out with a small turn to the right. Our durable design will help your fuel saving needs for many miles to come!
Why no switch?
If you turn the knob all the way left… you are at stock setting. Why complicate things? With one simple knob you can go from stock rich to so lean your vehicle is stalling. Super simple is our goal and doesn’t get any easier than this!
