best HHO MPG booster EFIE controllers

i have researched, checked into, and used a variety of different priced O2 sensor EFIE controllers for hydroxy/ HHO mpg booster systems. my old dodge truck doesn't use one, most diesels wont. all of your newer cars need this component as part of your hydrogen on demand system, which ever system you use, dry or wet cell etc. most cars will need this gadget. the really cheap ones like on ebay, are, well, lesser quality. unsteady output. there are a bunch for sale that are overpriced old tech. these are very resonable, and top quality for performance and reliability.

When a fuel optimizing hydroxy electrolyzer cell is installed,-aka HHO booster, hydrogen on demand. the petrol fuel is burned more completely. so now there results more O2 from less unburned hydrocarbons, the computer will read this as a "too lean" air/fuel mix. In other words, what is now a desirable condition in the exhaust, will be computed as "not enough gas", and the computer will direct the fuel injectors to increase the amount of gas being pumped into the engine. (via pulse width)

the short story is that the oxygen sensor and computer prevent the MPG we are looking for.


The oxygen sensor, is a silicon diode that when hot, reads what the oxygen content is by generating a low voltage on it's signal wire between 0 and 1 volt. 450 millivolts (.45 volts) means that the fuel/air mixture is correct. Higher values means the mix is rich (has too much gas), and lower voltages means the mix is lean. By adding voltage to the sensor's output, we can compensate for the additional oxygen in the exhaust.



some cars have oxygen sensors both before and after the catalytic converter. some have one on each bank. simpler FI systems just have one.
