Once again, I'm comparing my setup to RadGenH2O's on youtube, he owns the same truck as I do, same year, same engine. He is outputting a bit more HHO than me, he's at 3.5 LPM and I'm at 2.3. Additionally, he has placed two O2 extenders on the pre-cat sensor *AND* two on the post-cat sensor. I've only placed two on my pre-cat sensor, I don't see why I should need to do anything to the post-cat, but am beginning to wonder if there's something I'm missing here.
When RadGenH2O was putting out 2.5 LPM, he had one extender on each sensor and was seeing large amounts of soot on his sensors, my sensors are clean as a whistle both before and after extenders. I know that Rad played with a MAP adjuster for a while, but gave up on it.
The fact still confuses me that Rad saw a 33% increase in highway MPG and 50% increase in city. So far, I've seen some increase in city MPG (although this was over short distances, I don't do much city driving) and barely 1 MPG (which could be cooler weather) on the highway.
My system is now pulling just over 30 amps, I don't want to push this anymore as I've noticed that the alternator cannot keep up at idle. When I stop at lights, the battery meter visibly ducks down below the mid mark unless I turn off the AC. Rad has his alternator modified to increase output, he's currently running about 40 amps to produce his 3.5 LPM.
Part of me wants to go the leaning route, maybe through the MAP and IAT sensors as I've been advised by other Ram owners, but I'm worried about over leaning and having EGT issues. I'd really like to be in a position where I have an EGT gauge before going this far. I'd also like more visible evidence of the HHO's effect too before I work further or spend further money which I don't have to burn.
I think a good step, as Jaxom said, would be to hook up to the computer and see what's going on there. I have a laptop, that's not a problem, but will still need to spend out on the connection hardware. If anyone has any pointers to do this on the cheap, please let me know.
I started building a cell for my wifes car yesterday, it's going to be another PDC but with just 7 plates and 5 neutrals. This is mainly to give me something constructive to do whilst I bash my head against a brick wall over my own truck. Hopefully, I will have more success with my wifes 2003 Hyundai Elantra whilst I try to figure out my Ram.
