Camry from ????

[hydrotinkerer]

I give a little background. I have a 95 Toyota camry obd1 2.2Ltr. automatic. 30mpg base. My wife and I drive 130+ miles a day for work. I put gas in this car every 2 days. I drive the same roads and speed all of the time.

I have been fighting this thing for three months trying to get mpg's out of it. I have tried all kinds of generators. I have finally settled on using dry cells. The cell in the car is the 10.5x7.5" cell. My fuel mpg's with no electronic mods. went down 7mpg with this cell. I figured I must be on to something. About 1 month in I ordered an Efie from eagle. While waiting on it I ordered one from fuel-saver. They both came on the same day.
I hooked one up and adjusted it to 100mv turned on my gen and off we go. My mpg's went on a roller coaster, 30,25,34,27,32,24,30 you get the idea. I changed Efie's(thinking something wrong with it)adjusted to same mv and off we went. Same problem so I checked for leaks, voltage to gen., amp draw, etc. Could not figure out why the mpg's were jumping around so much. I started changing the mv setting and made things worse.

I finally decided I'm going to play around with it. The first thing I did was unhook the Efie and bam mpg down 7 to 23mpg. It stayed that way for 2 tanks. The next thing was to change the gas hose location and BAM the mpg's went up to 35(17% increase). I'll be seeing if it holds that this week.

I took my 1/4" hose and adapted it down to a 1/16" hose and hooked it to throttle plate vacuum. Throttle plate vacuum is not the same as manifold vacuum. Manifold vac is highest at Idle and drops off as the throttle is opened. Throttle plate vac has no vacuum at idle and rises as the throttle is opened. I would have never considered it if I hadn't had so many problems. The last bubbler has white vinegar in it. I hope it offsets the Naoh in the gas. I'll check that later with litmus paper.

  Hydrotinkerer after switching to the throttle vacuum did you have any problems with the increased vacuum drawing e-lyte from the reservoir tank at all?

[hydrotinkerer]

I lowered the level about an inch just to make sure that didn't happen. I did put a empty bottle assembled like a bubbler to keep track of the electrolite level.

Well, here is a thought, LTCFisher said he put his injection point right on the air flow sensor and there was no need to change the O2 sensor or anything else... which is a great CONVIENIENCE INDEED.... I think we are actually introduceing an IMBALANCE into the system by feeding the Hydroxy gas into the system at the manifold ... maybe not at the vacume port
but certainly when I drilled a hole in the plastic snorkel going to the air sensor and stuffed a hose in it !<grin>
... its very Possable that LTCFisher found a way to get the fuel injected engine to work properly with the Hydroxy gas ! ... I have not tried moveing my gas injection point...YET.
but the more I think about it the more it makes sense to me !
...he says he didn't have to do a thing to the O2 sensor !  and that is surprising !
... but that is what we're AFTER !  and it may well be the injection point of the Hydroxy gas... and let the Auto's computer Know about the Hydroxy gas, and deal with it like any other thing it does... it makes allot of sense to me !
...
   See I told ya that Boy was Smart !... even if he has a funny name ! <grin><poke,poke>

I have my o2 enhancers unhooked right now. I'll run that for a few days and see what happens. Hopefully I won't get a cel.

[hydrotinkerer]

So far 1 tank was 35mpg and the next was 32. The second tank I ran the dog out of it. I still have all my electronics like factory. I put the 25 plate cell in today. I want to see what it does.

[Bob]

with the addition of the "Matt Valve" My gas milage made a big jump for the better
I was getting right around 30 to 32mpg and I got 38mpg from this last tank and the Hydroxy generator was OFF half of the time !!!!!!!
....
so you know thats gott'a be realy good gas milage !
...
I'm realy wondering about LTCFishers injection point and method... it makes sense to have the computer working with you instead of against ya !
...
I might patch the hole in the snorkel and re plumb the thing to the top of the air cleaner right at the sensor... see what that does !

Just filled up yesterday and got 26mpg. I'll refill tonight and see what it does. Might be the ecm catching on and readjusting fuel trim. I'll know more after another refill. If the mpg's are still down I'll rehook my Efie and try to get mpg back.

[Bob]

sounds likr that cars computer is fighting ya  Hydrotinkerer !
...
something is amiss somewhere !

Nothing a little hydroxy gas and a light wouldn't take care of. HAHA  Not really right now I need that thing. I'll figure it out yet.

Hydrotinker,
This is interesting! I think your '95 toy has the same ECM my '89 Toy truck has or very much the same. I believe the change to the 2 generation ECM was in '96 with Toyota. I'll be watching closely your progress cause it sounds like you are having the same problems I am. Is your Camery a Calif car with all the extra emission stuff?
Tink

[hydrotinkerer]

Its federal emission but its probably the same as your truck because in later year models they started adding all the emission stuff. I just filled up again tonight and it only got 27mpg. I'll hook my Efie up tomarrow and check my cell to make sure nothing happened to it.

Hydrotinkerer:
  what exactly have you done to the O2 sensors ? on your Camry ?
and what is this EFEI thingie your talking about  is that supposed to fool the O2 sensor or change its signal to the computer ? or is that for the Mass air flow sensor ?
....
I understood that all I needed to do was change the O2 sensor to be out of the exhost flow
and my truck would reap the benifits of the hydroxy gas....well, its not quite that simple
but its not too far from the truth... I've only changed one other thing and that is I added a "Matt Valve" that bypasses the Mass airflow sensor. and seams to realy lean the engine out well... that and a thin pipe over the O2 sensor is all I have done and I'm getting better milage now than I ever thought my truck would get a year ago !
its gone from about 22mpg to a constant 38mpg but my hydroxy LPM is down again or it would be up above 40mpg I am quite sure on that !
...
I am thinking that your Doo-hicky isn't helping much at all  so maybe its time to try the mechanical approach.... extend or cover the O2 sensors then add a "Matt Valve" and see what ya get....
I think the Matt Valve is the biggest contribution to my milage yet... thats just a garden hose from the top of the air box (between the air filter and the Mass air sensor) to the other side of the mass air flow sensor... just a by-pass hose with a valve on it to adjust how much air goes through it...

The Efie is an electronic o2 voltage adjuster. o2 voltage when viewed on an oscilloscope is a constantly changing voltage. Most narrow band o2 sensors range in voltage of .00-1.00v. What the Efie does is piggyback an adjustable voltage that you choose. Like mine is set at .150mv. With the 150mv adjusted on the Efie no matter where the o2 voltage goes it always adds the 150mv voltage. With the 150mv added the ecm thinks the exhaust is richer than it actually is. You can hook one up without any sort of gas enhancement but it will burn up an engine and you will only gain 1-2mpg. I already tried it and I only ran it for a couple of days just to see what kind of difference it would make on its own.

Hey Bob; that Matt valve works on a bunch of stuff hahahahaha
