Hydrogen powered is more complicated then it is simple.

1thing to remmeber Gasoline burns, and hydrogen...well it explodes.

I think you need to understand how your fuel burns, gas "fumes" ignite, just like hydrogen, what you probably do not know is when your fuel injectors spray gas into your cylinders with air (atmosphere 78% nitrogen and 21% oxygen) and a spark is applied by the spark plug only about 25% of the fuel sprayed into the cylinder ignites! The other 75% is pushed out to the catalytic converter to be burned up so we do not have as much pollution! So just remember when you fill up your tank only one quarter of that fuel is really moving your car! The other 75% is wasted! Which is what *BLEEP*ed me off enough to learn about HHO technology.

That is why after 1996 every car had to have a MAP sensor and an ECU to make sure your car is running inefficently! $.38 per gallon fuel tax to the Government. Would you give up that revenue if you could stop it? That is why there are not electric cars! Technology is there, look at the EV4 and why it disappeared.

HHO technology does not store hydrogen in any amount, it is an on demand system that uses all the hydrogen as it is created. Large explosions with these systems is unlikely and would not damage your vehicle if one actually happened.

My father is an ASE certified mechanic and I help him a lot in his shop and we have been studying how to convert my SC300 to run on hydrogen and gas. I was wondering if anyone has done this to their SC and if they have any tips that will apply to this particular car. Right now, we are planning on doing a HHO generator, bubbler, EFIE, fuel heater, water vaporizer, PCV enbhancer and a MAF MAP sensor. We are hoping to get at least a 50% increase in mileage off of all these gas saving parts. If you have any questions on what we are trying, don't be afraid to ask, Isaac

Well, buddy, I have had HHO on my 92 SC400 for 9 months. You are doing the most difficult car on the market to do. I worked on my HHO stuff and did my sc first, every other car I have done since has been a cake walk. First thing you want to know is you are going to have to custom make your HHO cells and place them infront of your radiator. Second you will wire power for your cells through your ignitors, see a wiring diagram to determine which line is the 12 volt supply line. You want to do the dual line modification to your last cell and place one line to the air intake and the other on a vacuum line. You will not be able to use a MAF/MAP enhancer! You want to check to see what kind of MAF your lexus has. 90-95 have the Karmen-Vortex MAF sensor. This is the most difficult to wire around. I am currently looking for someone with an electronics background to do one because unlike most sensors that work on signal strength, the Karmen-Vortex sends a metered band width signal( 5 volt square wave signal that varies in frequency) to the ECU. The closer the band widths are the higher the signal. Soooooooooooooooooooo, just leave it alone. Get a duel E.F.I.E. (they are about $150.00 on ebay) and wire it into the two O2 sensors that are before the Catalytic Converter. Take your time and have a excellent wiring diagram to link into the sensor signal from the O2 sensors and the ECU. I would also recomend the fuel heater and the PCV enhancer. I also use pure napthalene (you can find month ball made of pure napthalene but it must be pure, 1 moth ball per 5 gallons of gas or you run the risk of affecting the lubrication of the cylinder) to increase octane so I can run on regular gas. It will take you about a week to dial in your E.F.I.E. properly so take you time. YOu will be happy with the results and if you find someone to figure out how to take the MAF/MAP enhancer or the E.F.I.E Enhancer to work on the type of signal or the Karmen-Vortex MAF, PLEASE let me know!

I am hoping to find a by-pass to the Karmen-Vortex to increase milage per gallon. For those of you doubters, I took a 1999 Honda Accord LX from 23 mpg to 38mpg city driving and 27mpg to 44mpg highway! The NEW Honda Hybrids only get 33 mpg! This technology has been around for 50 years and has been supressed in favor of corporate profits. By the way, you think gas is back under control, you are wrong! Gas prices have fallen only to mask that EXXON/ MOBIL posted the highest profits of any corporation in HISTORY in there 3rd Quarter reports. When the attention is divered gas will be back at its former ridiculious prices.

I have a 92 SC400 and have placed HHO technology on it to improve gas milage. It has raised me from 16 mpg to 23 mpg city driving, but I had to wiring around the o2 sensors to change the signal to lean the fuel mixture. However, when I have modified other cars (honda, fords, etc.) I have modified the MAP sensor and just pulled the o2 sensors out of the exhaust stream. My trouble is the Karmen-Vortex Mass air flow sensor on my 92 sends a band metered width signal my normal MAP Enhancers cannot replicate. Does anyone know how to set up a electronic adjustable enhancer to change the metered signal to the ECU to tell it to lean the fuel mixture?

Just changing the plugs and wires won't take all day. Maybe a short afternoon....couple hours at most.

Remember to use some anti-sieze compound on the threads of the plugs. You are dealing with an alum head engine.

An off line stumble could be a couple of things. I havent read all your posts, so if you would answer me this:

How many miles?

Condition of the throttle body?

Is the SES light on or do you know if any codes are present?

Have you ever done this before to any vehicle?

Do you know what type of gas was run in it before you got it?

A fuel system treatment may solve the problem if your injectors are dirty. You will find out soon.

SCdriver's technique works, but I do the first run with 1/2 tank and run down the interstate as fast as I dare.

I used the NGK V-power plugs and they are working well.

Another thing to consider (or at least check) is the condition of both dist caps and rotors if you really want to dive into it.

I changed mine the other week, it was worth the trouble as they were original with 160k on them (just like the wires).

It made a noticable difference in performance, fuel consumption and overall operation.

All that did take a good part of the day.

I ended up removing the p/s radiator hose to get the access I wanted, but the coolant needed to be changed anyway.

Please stop using ALL CAPS. People will think you are yelling, and it's kind of eye painful.

Hello thanks for replying back, I have gotten alot help from you guys and I really do appreciate it dearly. Okay,

first.

1). It has an 159,200 miles on the car; when I purchased it , it had 158,760 miles. And after driving it for about 60 miles and putting the medium grade gas in, and after that half a tank ran out that's when the problems occured.

2). The throttle bottle appears to be in great shape as most of the car is. The car is in about 92% in great condition

3). No the SES light is not on. The check engine light just flashes every so often and that's it!

4). And yes I have done this before, just not on a Lexus/Toyota. A product of Honda Accords.

5). And the previous owner always ran Premium gas the whole time. And I did not just this one time and look what happens.

And I will take SCdrivers advice and your advice as far as the caps and rotors. And I will stop using the CAPS all of the time, okay!!! AND TOO ALL AGAIN THANKS! AND I WILL TURN OFF THE CAPS, THANK YOU!!!

Hey guys, about your premium fuel situation. I have been researching alternate fuels and have put HHO technology on my car. With gas prices throught the roof I went to adding napthalene to my gas to improve octane. I found that 1 moth ball of pure napthalene (it has to be pure) per 5 gallons of fuel raises regular 87 octane to 97 octane for about $0.04 a gallon. I have been running my 92 sc400 on it for 8 months and it really runs great!
