| EFIE: Electronic Fuel Injection Enhancer As you can see from the title, EFIE stands for Electronic Fuel Injection Enhancer. This is a very accurate name. This device was developed to modify the Oxygen (O2) sensors signal in fuel injected vehicles. EFIEs are the best solution for obtaining improved fuel efficiency in computer controlled vehicles with oxygen sensors. This includes virtually all cars and trucks today. The EFIE is not intended to be a fuel saver by itself. You must install a hydrogen gas electrolyzer (hydrogen generator), or other device that gets more power out of the same fuel by increasing the efficiency of the burn. (Click here for more about hydrogen generator) If all you did was add an EFIE to your car, with no other fuel efficiency system, you may actually lose some efficiency. You might even damage your car, by over- leaning the fuel/air ratio, and overheating the valves. The EFIE was designed to make the car run according to spec after another fuel efficiency device has been installed. With no modifications other than HHO, performance increase and smoother idol are immediate. However, when installing an HHO electrolyzer (hydrogen generator) in a newer car more should be done to achieve significant mileage increases. After we introduce HHO gas the oxygen (O2) sensor reports a change in the exhaust gas makeup to the computer. The computer in turn tries to correct the perceived problem by dumping in extra fuel. This state usually turns on your check engine light, sets fault codes and puts the computer in a state called open loop. In open loop the computer stops modifying the fuel ratios and reverts to a “safe” mode. Safe mode dumps extra fuel. This can reduce the mileage benefits dramatically. The EFIE will get us back to closed loop by adjusting the signal to the computer, thus allowing the correct adjustments for various driving conditions to be made. Basically, the oxygen (O2) sensor tells the computer it's oxygen readings by providing a voltage between 0 and 1 volt. In order to adjust this "data" the EFIE adds a small voltage to that delivered by the oxygen (O2) sensor. This added voltage compensates for the variation caused by HHO. This EFIE is highly adjustable. Adjustments to the trim screw can change the EFIE's voltage correction by tiny amounts; a millivolt or 2 (.001 volt). This can be done on a much more basic level by adding an oxygen (O2) sensor spacer or two. The O2 sensor spacer pulls the sensor out of the exhaust gas flow, making it less sensitive, and causing the computer to lean the fuel mixture. The spacers are a mechanical solution and therefore not adjustable, some have great results, some not much. Oxygen (O2) sensor spacers are cheap, easy to install, and fit many vehicles. I have spacers available in other listings. Don’t buy spacers without metal gaskets, they may not seal properly. Spacers with tapered sides may wedge in your exhaust and become un- removable. This EFIE (Electronic Fuel Injection Enhancer) circuit board will modify the O2 sensor signal, and is adjustable. This circuit board installs online between the oxygen (O2) sensor and computer. This device requires a higher degree of skill and automotive knowledge to install. An EFIE board will be required for each pre-catalytic converter sensor. I have single boards for vehicles with one pre-catalytic O2 sensor and dual boards for vehicles with two pre-catalytic O2 sensors. Some vehicles have more than two pre-catalytic sensors; in these cases more than one board will be necessary. Both of these units have been designed to be economical, versatile, easy to install. They are easy to adjust to your particular car and fuel saver combination. Please check your car or a wiring diagram of your car to determine how many pre-catalytic converter oxygen (O2) sensors you have. A diagram will be helpful for installation also. Please don’t ask me how many you need, there are far too many vehicles for me to track and I don’t have time to do research for everyone. In my guide I will tell where to get this info free for most vehicles. What is the difference between the Deluxe and basic EFIEs? Deluxe EFIEs have most wiring and tuning challenges solved for you. The access and tuning is made much easier by providing the whole unit in a nice box which the installer can locate in a very accessible location. A power switch and LED ensure full control over the unit. Monitoring ports on the unit provide easy access to the signal and accept standard multi-meter probes. Adjustment knobs on the front make tuning the EFIE much easier. All EFIEs I know of install the same way so don’t think any one is easier to install than another. However some use poorer circuit designs with lower quality components, so don’t get stuck get quality. You can also be assured that you are purchasing from a knowledgeable mechanic with years of experience who can provide technical assistance and product support. Beware of the copy cats who wont help you because they don’t know how. *** Use of a MAP enhancer is not necessary when using an EFIE. *** As understood, the purchase of the EFIEs come with a detailed installation guide. This is not an oxygen sensor simulator - it will not allow you to remove the catalytic converter, nor will it modify its performance. The oxygen sensor simulator is for testing purposes only and not for use on street vehicles. You will receive: 1 Deluxe Dual EFIE or 1 single Deluxe Single EFIE, depending on your purchase, (5" x 2-1/4" x 15/16") size. 1 wiring harness with 5'-6" inches of wire 1 eight page detailed installation and tuning guide with diagram and pictures To order the Deluxe Dual EFIE or the Deluxe Single EFIE click below.
