  2. I sent you an email and it bounced back.

  3. 1992 toyota 22-RE EFI- CAn i make a HHO enhancer for my pickup?Oxygen sensor has 4 wires?i have a HHO generator already.
    Thanks

    By luciano on May 29, 2008

  4. There might be a way to bypass the o2 generator or try getting an EFIE device from the link in the article.. Different cars have different sensors, but the folks that make the premade EFIEs should be able to help.

    The sensors only work effectively when heated to approximately 800°C, so most newer lambda probes have heating elements encased in the ceramic to bring the ceramic tip up to temperature quickly when the exhaust is cold. The probe typically has four wires attached to it: two for the lambda output, and two for the heater power, although some automakers use a common ground for the sensor element and heaters, resulting in three wires. Earlier non-electrically-heated sensors had one or two wires.

  5. What happens if you forgo the EFIE kit and simply pull the fuses on the MAP oxygen sensors (in my Saturn, one in the exhaust manifold and the other aft of the catalytic converter)? Will that disable them and allow the HHO to to get mileage gains? Or do the reactant metals in the sensors run independently of the car’s computer?

    By Joe Shea on Jul 7, 2008

  6. if you pull the fuses your ecu or computer will guess that the units are damaged and will add more fuel or make it run richer in order to keep you from running to lean and burning your valves.

  7. To the person with the 1992 Toyota pickup. I have the same style p.u., you will find the 4 wires from your sensor are Brown, Black, Pink/with blue, and White/with red. The brown is the signal lead and runs between 1 and 9 Millivolts. Youll find the sensor just ahead of the catalytic converter on top of the exhaust pipe. I wrapped the inside part of the sensor with tinfoil to reduce the amount of oxygen it senced. When I installed my HHO generator and water vaporizer, and ran the system I found a voltage of 5 millivolts being produced, which is about perfect for your engine computer. The wires run inside a loom on the passenger side of the engine. You can do your testing at this location. Mine runs pretty nicely this way. Good luck to you, Gary

  8. Does the 2004 CL500 need an EFIE with HHO generator?

  9. i have a 1987 cadillac seville and i inatalled a kit for hho that i assembled and hooked it up without any enhancers and i tested it for making hydrogrn and it din not increase my mileage.so what would be the problem

  11. hi i have a 1998 hyundia sonata auto 1997cc injection engine will i need a EFIE thank you

    By keith on Nov 20, 2008

  12. are you selling a efie for £30 including pp thank you

    By keith on Nov 24, 2008

  13. im interested in buying an efie but we dont know if it needs 2 efie’s or 1 as the vechile has two oxy sensors, my vechile is a 2.7 v6 dodge magnum 2005 so can you let me know and will you supply me with what i need as im going into fitting the systems in england, and can you give me a price for shipping heres my address in england so you can check for costings: dean bulman, 141 southcoates avenue, hull, humberside, england, hu9 3hf, thanks deans

    By dean on Nov 26, 2008

  14. I have been reading that a 4 wire O2 sensor does not work with a regular EFIE. I have read that if you find the pulsating wire going to the O2 sensor this is the wire to hook the EFIE unit to. Then I read that nothing works on a 4 wire O2 sensor. What is the truth about the 4 wire O2 sensor? Should I buy an adjustable EFIE that will totally by-pass the O2 sensor? I see one advertised that does such. I the EFIE is turned off things operate as normal but when the EFIE is turned on I set the the ohms and it operates off of the EFIE and not the O2 sensor.
    Can you please reply by this E-mail for me I would appreciate it. As of now I do not know what the hell to do, EFIE,no EFIE or what.
    Thanks

    By Richrd Weaver on Nov 27, 2008

  15. To Richrd, about the 4 wire O2 sensor. I have the same problem you have. I have a 2001 Toyota Camry with a 2.2L engine. I read if you have a 4 wire sensor there is one type that will still work. We have a wide band sensor. If it is classed as a Air Fuel sensor there is no such device on the market that I know of that works. If it is still called a O2 sensor you might get lucky with the products around. I’m thinking we might only be able to buy the O2 extender to place the sensor 3/4 of a inch back away from the pipe. I don’t like the idea if you don’t use the HHO generator.I still don’t know what to do? Some one please help us out…

    By Jim on Dec 4, 2008

  16. Hi, yes I agree is a problem to by pass the
    sensores, yet I may be able to help.
    I designe a digital controler that as tested on
    menny cars, and so far so good.very easy to conect (3 wires) one switch that is on for savings, off to by pass to revert to standard.
