In the early days of HHO gas generator technology, many vehicles were unable to have fuel savings higher than 30% due to the strict parameters of their computer management systems. These cars have electronic fuel injection with advanced ECUs (Engine Control Units with Euro modules IV and V) and some would simply not allow fuel economy to improve beyond certain programmed values.

As HHO Gas Generator technology advances, more vehicles are able to benefit despite these ECU limitations. The new HHO generator EFIE Chip (HEC) is one of the newest products to address and solve the limitations of many modern vehicle ECUs.
With the new HHO HEC your fuel savings can go up significantly. When using hydrogen gas as a fuel supplement, the HEC will adjust fuel delivery and timing to optimize efficiency. When HHO Gas Generator is disabled, the HEC will automatically re-adjust and switch to highly efficient, non-HHO enhanced maps.

What is a HHO EFIE Chip (HEC)?
The HEC is a chip, with a 200 mhz microprocessor, It utilizes its high speed serial input/output to communicate directly with the ECU through the OBD-II port It has been specifically developed and tuned for the needs of HHO Gas Generator equipped vehicles. The HEC is dynamic - which means the HEC will consider oxygen levels in the exhaust, along with engine speed and load, intake air temperature and volume, and many other variables to determine the most efficient fuel delivery rate and timing at up to 256 separate load points.

The HEC is a vehicle specific, custom programmed 20 MHz microcontroller. It utilizes its high speed serial input/output to communicate directly with the ECU through the OBD-II port.
The HEC is compatible with factory equipped Turbo/Superchargers, diesel engines, Flex-Fuel, & HHO generator supplement systems. It is NOT compatible with hybrid engine options, propane, or natural-gas.

How does the HHO EFIE Chip (HEC) Works?
Inside every ECU there is a three dimensional table of values called a Map. This table tells your fuel injectors exactly how much fuel to deliver based upon current air temperature, density, engine speed, throttle position, and other variables.
From the factory, the map is generic and designed to provide a sluggish, no-surprises style of driving that suits a wide range of drivers. It is especially ignorant to the benefits of HHO Gas Generator systems and their ability to burn fuel at a much greater air to fuel mixture ratio than usual.
HHO EFIE chip corrects this problem by providing a pre-programmed and highly tuned map for the ECU to reference. The tuned map contains a set of variables that directly allow a better fuel efficiency. When the ECU attempts to read specific factory settings, the flash chip patches the factory value with one from its tuned Map.
In this way, when the HEC chip recognizes an HHO Gas Generator system is operating, parts of the factory map are temporarily replaced with improved variables from the tuned maps. This technique safely unleashes your engine's ability to use less fuel and it doesn't void the warranty.
And yes, it's easy to remove and restore the computer to factory settings when desired.
How to Install?
Simply locate the OBD-II port, connect the HEC Chip to four wires found BEHIND the port, and you're done. Bring the vehicle up to operating temperature and then press the reset button to start saving fuel.

Whats the difference between the normal Chips and the HEC?
The HEC is much faster than the regular Chip, which means faster & more consistent gains. The HEC also sports more memory than the regular Chip, so we are able to include more HHO gas specific coding.
