As far as someone else doing the "hard work" for me, not really the point. If you have electricity, watch tv, drive a vehicle, have running water, etc. then someone else did the "hard work" for you as well, but this doesn't stop you from taking advantage of someone else's findings. I 100% intend to help spread the word and help others with this technology once I fully understand it. So why shouldn't we try to make easy on each other?

I agree and hope that Admin decides to put that database together as it will really help. I fully intend to get these systems working on my personal vehicles and then help everyone I know get better mpg. If enough of us do this maybe we can put a dent in the fuel demand and force Big Oil to drop their prices. Prob won't though because somebody is putting together a nice large off-shore acct, but we can at least all try.

I don’t think you can fool the computer there are too many sensors sending data. The computer looks at them all and they change with every minor adjustment of driving.

To take total advantage of H.H.O. you would have to hack the ECU with all new values so it will not throw the BULL  S**T  FLAG and use pre-programmed values.

My test vehicle is a 2005 Chevy Uplander  with extra equipment and added weight when new it got about 26mpg now at 218.000 my first test run showed 23mpg. I installed 1 Electrolyzer and the PCM Enhancer. My next test run was 41mpg (same test 61 Milles) that did not last. I did the same run and got 20mpg. The same sad story as a lot of other people.

I use a scan tool that is hooked to a laptop computer and monitors all sensors in real time (BTW my Chevy has a sensor for the cat temp about 850 normal 820 with H.H.O. ). I checked before any modifications and after installation everything still looked within range  and no error codes, but still 20mpg although nothing was far enough out of range to create an ERROR CODE the computer did not like the overall readings and was running full ritch

To make a very long story shorter , the computer and I comprised. After trying many different things what worked for me is 1 o2 extender pre cat and 1 02 extender post cat . I now get a steady 45-50mpg and that is over several thousand miles. I’ll take that for now.

I know that is not near what is possible for this vehicle my PCM Enhancer will not lean the mixture at all it has no effect. I can dial it down until I get an ERROR light with a code PCM voltage too low but the fuel bank sensor dose not show any change.

I say I know that this vehicle can get a much higher mpg because as good as I am getting the computer is cycling between real data from sensors and default values (good mpg and full rich). I can watch this on the monitor it will cycle about every 2 seconds from 60mpg to 30 mpg as an example. This is probably why the PCM Enhancer dose nothing.

Sorry for  the long post but you are correct to take advantage of  this technology we need more people experimenting  on fixes for the ecu that is where car makers protect their investment.

There is a lot of information on the web on how to hack the cars computer, It may end up a lot easier to change a chip in the ecu then all the other modifications needed to fool the sensors.

BTW I own an auto repair shop and have 3 over the road service vehicles that’s why I’m testing the uplander. I love to read and gather information but hate to type. I have spent countless hours in forums reading and this is my first post ever, so please forgive a noobie.  

I put a small system on the 250cc scooter and works fabulously, Just Electrolyser and Fuel Heater. The carburator likes it and I doubled the mileage.

Howg !

I am assuming when you had just the 1 o2 preconverter and 1 o2 after, you were still using the hydrogen generator?

So you have a 2005 OBDII Uplander and are not using any EFIE's right? Just O2 extenders, H.H.O. and that's it? I wonder if the your vehicles ecu is a little diff then others because almost everyone here (on this forum) that has an OBDII has got to use EFIE's to get any real results. This is very interesting
