HHO EFIE

In case you may not know this, if you are installing an hho dry cell on a fuel injected vehicle, most of these vehicles will need an EFIE. This is short for Electronic Fuel Injection Enhancer. The EFIE corrects a problem with the 02 sensor which after an hho install will send a signal to the vehicles computer telling it it is running too lean. The computer will then send a signal to the fuel system telling it to dump in more fuel, when this happens the vehicle will run too rich and you will lose any fuel savings you were trying to gain by installing the hydrogen generator. EFIE's correct this problem. Be sure to give your vehicle information to the seller so that they can make sure you are buying the correct EFIE.
