What is an Electronic Fuel Enhancer, and do I need it when using a Hydrogen Fuel System from HFS.

Review - March 5th 2026. 

An electronic fuel enhance module is an electronic Module that connects to an engines sensors to alter the sensor readings that control an engine "FUEL MAP" and force the engine ECU to;

1. Reduce the volume of fuel injected.
2. Alters the fuel injection timing.
3. Force the engine to run Leaner.

So, to increase the engine torque and fuel efficiency.

These systems do improve engine performance, but there may a "cost" in making an engine run more lean. Making the engine run too lean may overheat engine valves. The use of electronic Fuel enhancers involve tuning the engine ECU to the modified sensor readings and is often used in cheaper low efficiency Neutral plate Hydrogen systems. These faulty Neutral plate systems produce large amounts of steam rather than Hydrogen.

Our Hydrogen Generators are a Patented design that produces larger amounts of hydrogen (not steam), with reduced current from the engine battery / alternator. Our systems use Hydrogen/Oxygen only to make the fuel burn faster delivering more power with less Throttle and therefore less Fuel.

Fuel enhancers can be used with our hydrogen generators, but why have the extra cost of purchase and tuning, when Hydrogen gas alone does all that you want.

Gavan can be contacted on 0403177183 or via email: gavan@hfuel.com.au I can explain more of the advantages of OUR PATENTED System.

If you insist in using the electronic Fuel enhancer to further improve engine savings, We have a analogue unit that we have tested and proven to be effective. This unit is available in our shop. It can be purchased through PayPal or credit card or payment into our company account with NAB.

Above is a K40 module used overseas, and is Only recommended for Highway conditions, as on Rough roads the rectangle bars can fracture the top plate & leak Hydrogen.
