Hello and good day, I had to try the HHO out and see if I get any results, attached are pics of my quick homemade device. I do not know the volume or MPG increase yet. If there is an oncrease I wanted to build a better cell. I was thinking dry cell..

Pictures make it look like a tight fit. What are you using for catalyst? I really like the way you hooked the HHO hose.

I just use baking soda. I dont know what the best catalyst is; and I have heard of a few different combos, I didnt want too waste money.

I use Naoh because its not used up in the reaction and it was cheap.

that is an awesome setup. Be sure to let us know how much it helps your mpg. I would also like to see how such a new ECU responds to one of these.

I am hoping I Wont have to do any Mods to see the MPG increase, and I am also hoping the MPGs dont go down, But if they do it is a sign that my setup is working. I guess the O2 sensor will have to be modded...IF I do see an increase, I have alot of improvements and remanufacturing to do. I hope it works so bad. There are alot of nay sayers out there and I cant wait to say "look at my % increase. Once I get deeper into the knowledge of HHO, its game on.

Nice car. Have you considered these things?

• Baking Soda eats the plates readily
• PVC begins to soften at 140*F
• PVC fumes can harm catalytic converters and 02 sensors
• Baking soda turns into NaOH which munches on aluminum. Baking soda can also do this by itself.
• How will you keep mist and electrolyte out of your engine?

I love those cars and would hate to see it get F'ed. Also would hate to see the face of the unsuspecting consumer who buys the car later down the road with aluminum damage. See this thread:

I want to see results prior to investiong in a full on set up. My technical abilities are rather high and I know that two tanks of gas on this setup with a bubbler wont harm a thing! I will go to what the industrial pros use-Potassium Hydroxide! I want to see results first,,Thanks for the info

Hey guys,

I also have a toyota yaris as well, and am working on getting my HHO generator working. I have a simple 2 quart generator installed, and i have the HHO pulled through the vacuum line right in front of your where your hose is installed in intake. Is that an ok place, or should i move it to where yours is?

I have not done any extra modifications to the O2 sensors or anything of the sort. Also, ive heard of people using a bubbler. What are they and are they really needed?

Anyone else who has done this with a yaris, what have you guys done or what do you suggest i do to help my situation. I have not had any noticeable gains in MPG and ive driven it for about 2 tanks already.

Thanks a bunch guys.
I hope i can get some advice.

You need to treat the Oxygen sensors, actuall the AFR sensors in front and the narrow band for the rear. The signal wire for the wide band (AFR) sensor is called pump wire, make sure you get a good wiring diagram for your car and locate that wire.
