You have installed HHO system but still not getting enough fuel savings?

You want to know why? Your HHO system produces extra oxygen which makes its way into the exhaust and causing engine computer to ADD !!! fuel as compensation for added oxygen. So instead of saving fuel ECU just wasting it.

Solution?

E.F.I.E – Electronic Fuel Injection Enhancer originally designed by Eagle Research. The EFIE added inline with oxygen sensor to compensate for additional oxygen by adjusting o2sensor output. With E.F.I.E engine computer returns to the normal fuel delivery and you can enjoy fuel saving delivered by the HHO system.

What we offer is the third generation Digital E.F.I.E with active feedback which is designed to solve the issues presented in the original analog E.F.I.E and makes the HHO system tuning and operation a much simpler process.

So what issues does the original E.F.I.E have?

First of all if you have ever dealt with the original E.F.I.E the next sentence taken from the HHO forum describes the frustration experienced by all E.F.I.E users:

“…..You will probably find adjusting the EFIE to be frustrating at first. When you turn the adjustment screw, the voltage starts rising (or lowering) and keeps on doing so long after you've stopped turning the screw. It can take up to 10 minutes or more for the voltage changes to completely settle down. I have learned to set EFIEs similarly to balancing a long stick on your finger… “

For you information all the E.F.I.E devices other than D.E.F.I.E are based on the schematic provided by Eagle Research. Though you can find E.F.I.E with different circuit board shapes and some enclosed into the project boxes all of them the same design and there of the same characteristics and deficiencies. There is another type of E.F.I.E which based on the “AA” battery but it is not even worth time mentioning.

Let’s quickly dive into the original E.F.I.E design so you understand the challenges. The circuit designed around analog frequency modulator with a transformer where the final voltage offset supplied to oxygen sensor is adjusted via trimming potentiometers. The user has to fiddle with the potentiometer and let the voltage stabilize for about 5-10 minutes. Another issue which is not usually described by the sellers and maker of the original E.F.I.E is that device is very temperature unstable. Due to its analog nature the circuit’s output changes relative to the outside temperature which makes it almost impossible to achieve the desired output and ultimately HHO system performance.

Digital E.F.I.E or D.E.F.I.E for short takes care of all that making tuning of HHO system a much simple procedure. D.E.F.I.E is build with special chip set specifically designed for automotive application. D.E.F.I.E provides simple interface to set the designed o2sensor adjustment output. Since output value is instantly displayed on the LCD there is no need to connect multimeter or any other measuring equipment to the EFIE..

Original E.F.I.E requires turning the potentiometers with a screw driver to set the output though it is not clear how many turns produces how many mV and when to stop to not to break the pots. Since D.E.F.I.E utilizing digital control circuit with active feedback it takes the guess out of the picture. Output is clearly displayed and saved in internal flash memory.

DEFIE features soft start up feature where the output is slowly raised from zero to the preset value. The soft start up speed can be changed to slow , medium , fast and no delay.

Installation of DEFIE is very simple. Only four to six wires to connect. Two for power and ground and two pairs of o2sensor Input and o2sensor output wires. Installation procedure is the same as widely used analog EFIE from FuelSaver-MPG dot Com.

The installation and tuning of D.E.F.I.E is intended for skilled professional. Though installation is medium complexity and can be done by anyone with average electric/wiring skills. We suggest you seek help of skilled mechanic or car shop specializing in installation of such devices.
