Today larger and more consistent MPG gains can be achieved in both Gasoline and Diesel engines by using a fuel Saving Flash Drive in conjunction with Hydrogen Generators. Hydrogen Tuning involves updating of a 3-dimensional table of values inside your cars ECU called a map.
This map table tells your fuel injectors exactly how much fuel to deliver given current air temperature, air density, engine speed, throttle position. This chip is programmed for you vehicle with new values based on O2 sensor output.
By updating these reference tables in your car ECU so it recognizes lean burn condition when Hydrogen is introduced into the engine and adjust timing and amount of fuel being delivered to the engine you can maximize your engines efficiency.
