cpu resets= car learning?

H2OPWR/John,

I went to their website and put in the info. for my car, they mailed me back today...

James,
You have 1 narrow band sensor upstream of your catalytic converter so one of our single narrow band EFIE’s is what you would need.
You can get one in our online store at http://www.fuelsaver-mpg.com/store/

I already have the map sensor...does'nt that do what this efie would do?
This has me confused, I know I need to control the fuel sensor from dumping xs fuel and that is what the map sensor is doing, cutting back on the xs fuel delivery. I guess what I'm asking is "How is this efie any different from my map sensor?" Does'nt the map sensor take the electrical current and alter the attenuating flow to the oxygen sensor?

Thanks for the response guys.

I am getting away from the water4gas design, testing on my dry cell should begin tonight. Thanks Larry for the plate design and building/advice. I'll let you know how it goes.

Jim, I agree with Toyota. The MAP enhancer and the O2 are completely different animals. Running a MAP without an EFIE for your O2 will probably be detrimental to your over all ability to make gains. If i were only going to run one it would be the EFIE. By running just the MAP you are telling the ECU that the engine is not working as hard and does not need as much fuel. Then when the ECU leans out your engine the O2 see's a lean condition and richens the fuel mixture to get back to the 14.7 to 1 ratio it is programed to maintain.

You have two fuel trims to worry about. Long Term Fuel Trim (LTFT) and Short Term Fuel Trim (STFT). To simplify how this works the STFT is for the most part the table in your ECU that determines the amount of fuel that your engine needs. It compares the LTFT with sensor data to determing the length of time that your fuel injectors stay open. By running just a MAP you are setting the LTFT to a richer than normal setting. Your ECU is getting modified data from the MAP telling it that your car is not working as hard as normal needing less fuel as the air flow is lower. Then the O2 is sending a lean condition signal to the ECU telling it to richen the mixture. All this together is telling the ECU that your car needs more fuel per pound of air to maintain a 14.7 to 1 ratio. This rewrites the LTFT ro a richer table. Now as your ECU compares sensor data to the LTFT your STFT will now have a richer setting and you defeat all the gains the HHO might give you,

Sorry for being so long winded but I have access to some of the best techs and factory rep's and have been picking their brains about this for months. Beleive it or not this is the short story on how this all works.

I strongly beleive that there are just a few reasons most people fail with this.

1) Just not enough HHO to help.
2) Improper MAP/MAF EFIE enhancer combinations.
3) Impatience with adjusting the enhancers. Too big of changes to the signals from the sensors will confuse the ECU. The tables do not figure in enhancers to their calculations.
4) Running the vehicle without enhancers or HHO or both once the tuning has started. Again sending confusing data to the ECU.

Hope this helps.

So how do we know if we have a narrow or wide band sensors ?

i got a Toyota FJ 08.

Most Toyota's are now wide band but to find out for sure these people will look it up for you

You probably have 2 pre cat wide band a/f sensors and 2 post cat narrow band sensors. Please do not take my word because it is just an deucated guess. Verify to make sure.

Hi Jim,

Your MAP sensor and O2 sensors do different things. They are definitely not the same. You do need the efie that Bruce wrote you back about, and you connect on the signal wire of the O2 sensor that you have. There are detailed instructions on the fuelsaver-org.com, on efie installation, that you need to read so that you connect it properly.
They do work when properly connected, and with your MAP mod working also, you should be able to get some decent (25-35-maybe 50%+) results.
Hope this helps a little bit.

Easiest way is to email: support@fuelsaver-mpg.com , give them your vehicle year, make, model, and ask what type of sensors you have and what type of efies do you need.
They will tell you accurately and for free.

Larry,

Your explanations make sense, just need to read numerous times to let it set in. I originally thought just the map sensor was needed, so $$$ wise I just took that advice and ran. I'll get the efie shortly. Tell the Techs that their advice is much appreciated here.

John,

Your input helped a lot, without it I would not have realized that an efie is a necessity in my setup. I'll read the instructions carefully and report the results for others to learn. Thanks.

Jim,

Sorry, I made a mistake in the website name, it should be: fuelsaver-mpg.com . And the reason for the efie is that the O2 sensor probably has the biggest input to the engine computer for controlling the amount of fuel being used, so the efie allows you to have some control over it.

I don't know how to start off with my question. I've read somewhere that with the newer models of cars, effie, map/maf sensor won't help. And that the only solution is to install the HHO system and let it run on your car and resetting your cpu every few miles for certain amount of months then your car will adapt to it?.

If anyone can confirm that this works or a link to where i can get more info. It would be great.

Hey bud,
I don't know anything about HHO, but i DO know that my (2001) dodge dakota's computer (PCM) DOES 'learn' every time its reset. So, when i put my after market intake kit on, i reset the PCM, and it relearned what do do with all that extra air coming. They recommend this reset after cams and stuff too. but after that, it (the PCM) should "know and understand" what do do with the changes thereafter. I mean, i don't have to reset my PCM (Engine Computer) all the time (only per modification) b/c i have after market cams and intake, which, of course, alter the A/F ratios.

So, it stands to reason that once you reset the Engine Computer (PCM on mine..) WITH the HHO setup, you should be good to go. OF course i don't KNOW this for a fact, just trying to use some logic..

i hope i helped at all, i am an HHO noob after all. Just trying to contribute.
-Good Luck!
