I think he could get better economy with a small adjustment!

I still think the limit is in the .200 range of adding to the O2 thru the EFIE. BUT it depends on how rich the factory computer is and how much HHO you are pumping/sucking in to the intake, teh more HHO the more you could adjust the EFIE.....but from what I can tell from here in the past few days across many platforms, .200 is about the limit of getting good MPGs without setting the Knock Sensor off and creating issues.

On your 5.3 Chevy, you should be able to gain about 12% in fuel economy with JUST THE EFIE on the O2s, by dialing in a .100 to .125...cause in the files I alter here with HPTuners, we take out .100 from the O2 mV table and it picks up 12% on the hwy and depending on your daily commute that might translate into daily use or it might not, if you have alot of stop and go it's going to be hard to get to the right range for it to work.....I take it out, and you will be adding it, does the same thing actually, just in a different way...

And these results were on 350-360ish RWHP 04 GTO and 06 CTS-V, both experience 12% or 3MPG gain.

RE: Success Ford Van 1997 V-10
So you've seen 12% gains in mpg w/ dual EFIE's only?? I'm thinking I need 20% gain in mpg for my projected $650 investment (hydro super 2 double, dual EFIE's and MAF adjuster) to pay itself off in a reasonably amount of time. If only I could hear of someone w/ my setup getting good results....

RE: Success Ford Van 1997 V-10
NO, 12% gains in taking the GM Computer and changing some of the parameters, specifically the O2 readings that the computer is looking for to think it is at stoich, stock is .45x, we just moved that number down to .35x and got 12%, this was based on the Aussie's GTO with LEAN Cruise enabled and it's reported that this commands a 17.x:1 AFR when the conditions are met.
BUT with the EFIE's it is doing the same thing but in reverse, computer is looking to try and stay at 14.7:1 or .45x on the O2 readings, when you 'add' that voltage with the EFIE the computer thinks it is at say .55x (adding just .100mV) so it says I am rich, let's take out some fuel to get to the 14.7 or .45x.
Make sense?
And knowing that Honda is commanding 20x-ish:1 AFR on some of their vehicles I feel certain that we can pick up more than that 12% on the current vehicles tuned by going to .325 or .300 in the computer and that is where I am deriving that adding .200 on the EFIE has got to be the limit, unless you are dumping alot more O into the engine than what appears to be a common setup....
I should have the buick LeSabre I drive daily to work and everywhere else programmed to test the theory of how low I can set the O2 readings and I ordered a singe EFIE to put on my Grand Caravan to see what kinds of MPG I can get out of it, I assume 12% but Think it might could be more.....

And I think you will see a 20% gain in MPGs once the HHO system is in place and you have played with the settings to get it like you want it, I would say 20% is just the tip...based on what others have seen.
