RE: hydrogen - 4/25/2008 4:15:26 AM    rtsurfer   Posts: 51 Joined: 4/6/2008 Status: offline That was the original circuit I was working on. But somewhere after R4 the voltage dropped off to .0002. Which is too low. I will get it working. But I need to figure out what is going on with it. But the eagle research (first drawing modified) and the second drawing do the same thing. The ER one you are cutting the o2sensor wires feeding them into you circuit and then back out to the ecu. You are just rerouting the O2 wires but you are still just adding a small voltage. You can do that with one wire when you only have to send a signal out. I could not see spending the $60 for it. Plus I want to learn from what I do. (in reply to northey87) Post #: 181

Im pretty much waiting on two parts so I can finish putting it together. _____________________________ ''95 1500 Silverado, 350, flowmaster Force II exhuast, S&B CAI.

RE: hydrogen - 4/30/2008 2:37:56 PM    northey87 Posts: 841 Joined: 10/17/2007 Status: offline I have thought about doing that, the pulse modulater I am building has a POT that I need to attach to the throttle to increase the gas output when you step on it. I thought about tapping into the TPS but felt uncomfortable doing that, so I will just use the POT. _____________________________ ''95 1500 Silverado, 350, flowmaster Force II exhuast, S&B CAI.

RE: hydrogen - 4/30/2008 4:43:19 PM    73shark Posts: 2112 Joined: 4/17/2006 Status: offline I don't think you would need to worry as long as whatever you hooked to the TPS was fairly high impedance so it didn't alter the voltage signal to the computer.  Forgot to mention earlier what most here already know and that is since hydrogen is the smallest atom, it's impossible to completely contain it even in a heavy wall st-st container.  _____________________________ GM perf. exh, GM CAI, Superchips, Lund step tubes, billet grill, LED tails, Lloyd mats, rear console, GM flaps, silver calipers, black bow ties, tint (in reply to northey87) Post #: 189

RE: hydrogen - 4/30/2008 5:55:25 PM    EuroGoldLS Posts: 1957 Joined: 7/12/2007 From: Princeton, NC, USA Status: offline Plastic can't hold Hydrogen gas indefinately, no, but it can hold it long enough to introduce it into the engine. Helium is the second smallest atom, yet a balloon can hold about 70% of the helium over the period of a couple of days, and its a lot less dense than PVC. Not to mention that the hydro atoms are moving faster than the plastic molecules, so just from the state of matter, it makes it harder for it to pass through. _____________________________ NOMINATE someone for Ride Of The Month!!!
