what if you were to mix the solution at 33% and hook cells in series until the amps are brought down to an acceptable level?

that should work if you had enough cells to hook up !... but the more cells you hook togather the more amps you will need so in short order the optimum number of cells and right amperage will meet... probly in about 3 or 4 cells ! HEHEHEHEHE

Bob, I guess I am just going to have to build you a PWM since you to blind to see. What kind do you want? Just consider it a late Christmas present. I aint making it until I go back to work tho and thats jan 6.

Randy,
I suspect that using relays to switch in and out extra cells is the better way to control the current. You could even use a weaker mixture in the 'control' cells to bring the current back into line.
I've been experimenting with a small MOSFET ( 75337p) but it seems to get very hot even at low currents even though it's bolted to a copper heatsink.
I'm hoping that LtCFisher will eventually get around to telling us which mosfet he used in his four channel PWM.

200! I dont know about that. Let me just build one and send it to you. You can be the test pilot on the thing. he he
when I get thru with it, I will let you know and you can pay for the postage How about that?

HAHA Ok Scratch ! No hurry, No biggie take your time... and use extra big Mossfets cuz I'll work the fire out of it.... think OVER KILL... and make it IDIOT PROOF ! HAHAHAHAHAHA
(in other words a diode in line so I can't hook it up backwards ! alwayse wondered why more manifacturers didn't do that ... for the price of a simple diode it saves burning the thing up !)
...
Manta: I think Scratch posted a place a while back where he gets allot of his components on line and they had a raft of Mosfetts about any size you'ed want ...
dunno where he posted it though ! <GRIN> sorry !

Scratch,
Where are you with the MPG on your truck now? Since you mention getting 40 odd MPG before I think it could purely be a case of your computers adaptive memory learning it's way around the HHO. The more HHO you add, the quicker the computer will do this.
One way to prove / disprove this is to reset your computer. Disconnect both battery cables and touch them together for a few seconds, then leave them off of the battery for about 30 minutes. After you've reconnected, do an MPG test ASAP.
By the way, the rattling and pinging sound you heard is quite likely to be pre-detonation. With that high amount of HHO going into your engine it's quite likely that left-over chamber heat and compression are igniting the HHO too early.
Hope you get it sorted!
Russ.

I read somewhere that touching the battery cables togather is a no no... but Personally I don't see how it could be as you have to be able to re boot the computer some how!
.... just check your book first Scratch to be sure, cooking the computer would realy hurt the pocket book ! ...

Same as when I didnt have nothing 26 miles a gallon. I have to just get this computer management stuff figured. I have good production and I have a small motor so I will try the reset of the computer like you guys suggested and the O2 sensor capped off and see what happens and the matt valve too. That 40 was a one time deal I guess.

Scratch:
Try a orfice at your gas injection point, as you already know the cell can produce 40 psi., if sealed I have found that if you maintain a avg., psi., of (25-30) the system is more efficient and the gas can be directed and the gas pattern controlled (swirled, jet, or funnel spray) depending on the point of injection and surrounding structure. You can start on the bench with air once you know the psi. on the cell, take a piece of tubing seal one end and drill a 1/16-inch hole in it connect the air supply and and watch the regulator (set at 45psi) the air use gauge or constant gauge should read between 25-30psi constant. Re-drill the orfice 1/64-inch larger at a time untill you get the constant psi injection you need. If it drops below your target number (psi) start over. If you inject it ( the gas) just before the mas air flow sensor it will be a cold gas keeping the MAS wire cooler (like air escaping from the valve stem of a tire even when it's a Hot tire) the mas detects air temp crossing over it (it's a resistor wire, some have a coil), this will give you a base to start at. You now have control of the MAS when using the cell, next you can look at the O2 sensor with a digital meter tap into the wires (DO NOT CUT THEM) running the cell watch the meter easier with 2 people your target number here will be (.5-.7) or (5-7) depending on your meter setting. (DIGITAL METER ONLY) Anolog will not work. For a V-8 engine it seems to require 2 injection points 1 at the MAS and 1 intake manifoldboth equipt with check valves one is for idle and low rpm the other for driving ms. daisy to the store or highway use. I hope I helped you some.

Scratch :
I hate to admit it but I think my 40MPG was a one time thing as well, best I've gotten sense that one reading was 38MPG but that was after running the "Matt-Valve" for about a week
and the cell was purdy dirty at that time...and it sent into a steady decline from then on
.... to be honnest I don't know if its the trucks computer or the cell output that is giveing me the truble.... the cell almost quit working completely , so I know it wasn't working up to snuff ! ... but it may well have been partly due to the trucks computer as well
....I just have no way of knowing...
....
when I put the cell back on in spring I will keep closer track of the workings !
I am fairly certain that I can lean the truck out much more with the Matt-Valve with no Ill effects... and I think that will get me above 40MPG again... but I don't know that for certain!
....
LTCFisher:
thank you for the info ! I never thought of checking to see if my O2 sensor was still sending a signal to the computer.... dunno why but I never thought of it! HAHAHAH
that may well be part of my problem too !
thanks for the help !

thanks for all the information and suggestions Lt. Fisher. I will give those ideals some thinking and will try that. I know I have hit 35 psi or higher and leaks should not be a problem all I have to do is tighten more on the tero cells if that would become a problem. thanks again. Ok Bob, I just got thru putting (cant remember his name at the moment) well his stuff to make his pwm handle more amps. Its time for yours, so what do we want here a all in one or seperate it out like mine. How much room do you have to install your box around the dash area or what did you have in mine. I havent forgot about the amperage 200 he he.

Howdy Scratch ! sounds like you've been busy !
...make it easy on yourself... a all in one unit is probly the easiest... I can come up with the large heat sink if that is a problem to you.
I will probly use it under the hood, near the cell thats mounted on the frame rail, beside the engine.... and run the Pot and meter & switch to the dash... so having those 3 on wires not on the board would help a bunch....
I don't need freq. control as I am not planning on trying to resonate the cell but if its there (space between pulse I think it is) its all for the better !
I will build my cell to handle a max of 150 to 175 amps at top amp draw ( I think, not sure yet) although that seams low to me it should if nothing else get me to 75MPG
if I need more amps in the future I can make another, because if I have one in my hand I can duplicate it !
this will help me to no end Scratch ! and I really appreciate it ! Please keep track of the cost of parts, and how much time you have in it to make it... I want that info !<GRIN>
...
if you feel like makeing a simple 555 timer PWM that would be great as its probly far simplier and cheeper... all I need is a way to control 200amps without it smokeing more the marrier, so if you find 280amp Mossfets at nearly the same price go for them instead...
but if their $100.00 each ferget it ! HAHAHAHAHA
you'll probly need a driver to drive the Mossfets, or 2 stages if you use a 555 timer
... whatever you do ...PLEASE use a I.C. Socket for the chip so I can replace it should I screw it up! HAHAHAHAHHAHAHAHHA
....
BTW, my Sis bought me a TracFone and we have been messageing back and forth... problem is
I am definately on the fringe area here and havn't been able to get into town with it for 2 days ....( there is no external ant. connection on this phone darn it!)
...
thanks again My friend !

Something seems a bit odd here.
People seem to be talking about cells that produce somewhere between 5 and 10 LPM. yet at the same time we have claims of constant pressure of 30-40 psi with a 1/16" plus hole. Now, Hydrogen is a lot less dense than air. So it escapes through a hole easier than air does ,same sized hole. 30 - 40 psi is quite a lot of pressure. Some thing isn't right.
By the way, LcTFisher, opening a jet by increments if 1/64" is a huge increase in gas flow. A couple of thou' at a time is more reasonable.
