The engine's response to HHO injection

So, you would need to hack your ECU and remap the fuel and timing to lean out the mix and somehow regulate the HHO flow to keep from going too lean and frying the motor or total loss of power.

I did it! It works great and my Honda now gets 112mpg!

Waaaay back up this thread, somebody mentioned computer.

I used Pulstar plugs in my Tundra for a while. There was a performance improvement but no change in the MPG.
So far as I can tell, the computer is set to have 'X' exhaust gas parameters, and the more efficient combustion of the Pulstar plug was negated by the computer adjusting the mixture.

So...it seems to me you need to have a conversation with your cars computer to make any system that modifies combustion.

Yeah, I know I'm resurrecting this thread.......

Shatto, you plan on doing any hydrogen injection to your Tundra?

What other mods have you done to increase FE in these trucks?

I have done nothing.

In a while I will be due for tires and will upgrade to the new MPG tires and I may go to a bigger diameter tire, but I have not calculated the difference in RPM/MPG. Then there is messing up the way the computer works problem.

My research says intake and exhaust will improve performance but the possibly one mile per gallon improvement is so low, and the expense of changing out a perfectly servicable system is so high, that even with gas going up......let me put it this way; spending a thousand bucks is too much for the potential savings.

My daddy had a wire that stopped the throttles of his P-38 at maximum power. If he got so scared he kept pushing them for more power, like when tracers were going past him from behind, the wire broke and allowed the water injection system to work and there was a substantial boost in power to get away. Then they replaced the engines.

I have yet to see evidence that any of those fancy water or hydrogen or oxygen systems work. Guess I was really turned off when emails were not responded to. Maybe they just want me to buy their book.

Adding a natural gas system works. A Dutch guy posted an excellent tutorial on modifying his Dakota a while back, but unless I can get ahold of a Honda home hook-up, there aren't enough stations, even around here to justify the expense. Then there is the problem of installation. I need the bed to carry stuff, not fuel tanks.
Here, taxis use CNG because it allows them to use commute lanes when empty and because it is politically correct and because Ford sells the CNG version for about the same price as the gas model but they don't sell the dual fuel.

changing tires shouldn't mess with the computer though your speedometer will be off. it is the equivalent to changing out the rear end gears. basically, you are just gearing it different, the computer shouldn't care.

I am like you and have seen no hard evidence to say that these systems work. many claim they do but (in my opinion) are just out to make a quick buck.

the natural gas thing is interesting since I have gas heat. I wonder if natural gas is cheaper than gasoline compared to efficiency. I wonder if your cost per mile would actually get better with such a system. I know that NG used to be considered expensive. I haven't checked in a while. I just get the bill and send in my check.

Gearing changes can mess with modern computers that have to compute individual wheel speed differences for ABS and traction control. I don't remember all the issues besides ABS and TC.

With all 4 tires matching, it's hard to get enough gearing change from tire size to cause significant difficulty. Folks building lifted off-road 4x4s deal with it, but I doubt anyone here is looking at that type of size difference.

Interesting Shatto, my dad was supposed to fly a P38, but when they arrived at their assignment they realized they were going to fly a B17. Fall of 1943.
He flew 30 missions over Europe from Christmas eve of 43 until D-Day.

I always wondered what would have happened to a P38 if they had replaced the Allisons with Merlins, like they did in the P51.

traction control might be an issue but I always thought it looked at the different speeds of the tires themselves. basically if the back ones are moving faster than the front ones and not the actuall speed of the tire as it can't really tell the actual speed of the road moving beneath it. I really haven't looked into it though. many of the statements above are assumptions and I freely admit it.

I changed the gears in my truck from 3.55s to 4.10s one guy told me to borrow som 26" slicks and it would give me a feel of the gearing since I had 29" tires on my truck (all are outer diameter). I didn't do it but am glad that I changed the gears. I also got lucky because the speed pickup in my truc was on the axle so the speedo wasn't even off.

I assume as you do that he is talking about an inch or so difference in outer diameter and probably not much more. overall a very small percentage of change

[theholycow]

That is my understanding of how traction control works too, but for reasons that I don't understand changing the tire size really does affect it.

I don't recall an opposite rotation Merlin being available. I think there were griffons though, but they had altitude issues.

edit: doh, no the griffon was a success it was the peregrine I was thinking of..
