We talked about how injectors are controlled by the cars computer (ECM) to determine how long they stay open or closed, and how fast they open or close. The ECM decides those parameters using a programmed set of "fuel maps", that utilize the information from the cars sensors to determine if the engine needs more gas or less gas.
Computers can only do what they are programmed for. They can't tell if you are going up a hill or towing a trailer, or anything else, without reading the information from the sensors first. The two key sensors are the O2 sensors in the exhaust to monitor oxygen levels, and the MAF or MAP sensors that monitor the flow of incoming air and the manifold vacuum.
The sensors transmit the data to the cars ECM using very tiny millivolt signals. An O2 sensor may be in the 400 millivolt range for example. When you install one of our EFIE's, you use a volt meter to adjust that millivolt rating down to say 300 millivolts. By doing this, you are telling the car computer to "Lean Out" the fuel, which allows the HHO generator to supply the additional energy, and still save fuel (If you do this without adding an alternative fuel, you will notice a lack of power, and could even burn your valves, so ONLY do this when injecting a new fuel like HHO gas). AN efie gas tuner allows you to slowly tweak and test to get the optimum performance from your hho generator.
The MAF sensor works on the same premise, but measures the mass air flow going into the engine to determine the work the engine is doing (engine load). When you use our EFIE or Diesel Chip, you adjust them to reduce the engine load setting. In other words, you are telling the car computer that it has a 20% lighter engine load than it actually is (for example). The computer then reduces fuel because of that.
It is not as complicated as it may seem at first. You simply locate the one signal wire on a sensor and connect it to our EFIE or Diesel Chip, then adjust it with a screwdriver. After that, you never mess with it again. (we show you how to locate the wire, install it and adjust it in our free manual).
By changing the signals ever so slightly, you are teaching the car computer how to reduce the gas or diesel usage, when supplemented by pure hydrogen and oxygen gas. That is the Long term way to make your hho kit function as both an emission reducer and fuel saver, without loss of power or performance.
Stay tuned for Part 3 where we get into the Pro series level chips and how they differ from our advanced series.
