2005 f150 triton 4.6l v8-help needed
I have been working on this for several months and am hopinig that someone can help me see a vital step that I am missing. It seems that i have been following each step but I do not see a gain. This is verrrrry frustrating.

Here it is:

Smack booster style system with +NNNN- config. 6 plates only, fuel saver efie set at 280mv, the complete block of ss plates is edge coated to avoid current loss and heat with hi temp rtv, except a small 1" space on top, I am using liquid drain cleaner with koh & naoh in it. It draws 30amps and the water is at 140-160f degrees. I have no vac leaks and i am putting out .5-.75lpm. I have verified it with a 1 liter bottle test. The hho that collects in the bottle seems to be much thicker than previous configurations( like cigarette smoke). I am connected into the air intake only, between the maf and the throttle body. no check valves. I had a maf enhancer but I removed it as I was told that the efie would be enough to fool the ecu.

The following are the mileage results:

oem (no efie or hho) 17.43 mpg
efie & hho 15.69 mpg
just hho 17.09 mpg

I suspect that my efie is set to high and I might be in full rich mode, but my check engine light is not on. Can the water temperature impede the gain? Do I need more HHO? This weekend I will be adding another cell with a a full 16 plate assembly similar to the existing 6 I have now.


Can somebody help?

Thanks in advance!

With a V8 I would think you'd need at least 2 cells and I would turn the efie down to 150 or less for starts. I'd shoot for closer to 1.5 to 2 LPM.

You run 30 amps and you only get .5-.75 LPM? Did you use the latest Smacks plans? Did you wrap your plates and insulate your connections from terminals to plates? 30 amps with efficient cells should get you more than 2 LPM. One guy here was getting 1 LPM with 7 amps.

Best to increment your efie in steps of 50 mv until one of the following happens:

CEL
loss of power or other driveability issue
no gain in mileage.

I think you need a second cell before you spend much time tuning.

RE: 2005 f150 triton 4.6l v8-help needed
ok i am back after several weeks of tinkering with the system. I have installed a system which I took off a thread here of "3-5lpm" I am around 20 amps and am probably putting out close to 2+ lpm. It began to rain and could not check it. I will over the next couple of days. My efie is at 175mv. I assumed with the increase in HHO I should probably bump up the efie, so i went to 230 and the CEL came on again. I pulled my battery ground each time to reset it but it comes back on. I am in open loop and getting a grueling 11mpg from my factory of 16.

Should I be going down instead of up? Is there a sweet spot for this engine? I am going to reset it again and try 100mv and see what happens. The only increase I have received was one time when I unplugged the O2 sensors (before I got my efie) and it went to 25mpg but then the next time I checked it it was in open loop. Any help would be greatly appreciated.

Thanks alot ahead of time!

Tony

RE: 2005 f150 triton 4.6l v8-help needed
I have been reading the posts here and....
Just a thought, how many upstream sensors are there?
I don't know your vehicle but "IF" there were two sensors.
Lots of v8 engines do have 2 (upstream) sensors, so need to check what it has.
Both upstream sensors must have an efie, or you will not get the increase in mpg.
In that case it would need either two singles or a dual efie device.

I only have one O2 sensor to deal with on a dodge caravan 3.3 ltr v6.

RE: 2005 f150 triton 4.6l v8-help needed
I suspected that at one time. There are 4 o2 sensors -2 are between the cat and engine and 2 are after. I was told that the other two did not need to be enhanced. When I connected the efie I connected it direct at the ecu wiring harness. I am now thinking maybe I have it connected incorrectly?... I think I am going to retrace that connection.

The only thing is that when I installed the efie, I removed my maf enhancer on the premise that the o2 sensors control the computer over the maf.

I changed my efie to 100mv and reset the CEL and I checked my mpg and I am still at 11mpg. I have pulled the unit out again to repair a minor leak so I am now at Henry Ford's best.

I have not done a LPM check on my unit yet but I am convinced that I am producing something considerable (2+). I would think the computer kicking the CEL on as soon as I started my new unit is a sign that there is more HHO going into the engine and throwing the computer into full rich.

Are there any other possible sensors that we need to address other than the o2 and maf?

Thanks for your help.

I'd get the CEL read, it might be a lean code or it might be a MAF code from removing that mod. Many auto parts stores will read that code for free, but confirm before you go there.

It's ok to leave the MAF mod installed, but it should be set to a low level, no more than about a 10% increase (maybe a 1/8 turn of the knob).

Clear up that CEL issue then work on measuring your output.

RE: 2005 f150 triton 4.6l v8-help needed
ok, heres my latest update....I am no longer in full rich mode. But the system is out of my truck and I am totally factory. I just got gas this afternoon and I was at 16.89 mpg on factory.

I was questioning my install on the efie if it was correct at the wiring harness. I spoke to a service tech at a local Ford dealer and I want to share my conversation results for those that are not auto electronics savvy (like me). There are 4 o2 sensors, 2 upstream and 2 down. The 2 upsteam are the ones that we are looking for.

HERE IS THE INSTALL AT THE ECU HARNESS. I recommend disconnecting the battery before you do this.

Sitting in the driver's seat, Bank 1 is the right and bank 2 is the left. Sensor 11 is bank 1 (right) and sensor 21 is bank 2. There are 3 harness plugs. Now, facing the ecu, the plug you want is the left most (closest to the battery). Remove the harness and gently remove the plastic cover on the plug to expose the wires going into the plug. On that side of the plug are the numbers to each pin. The pin numbers are #28 and #29. See the attachment (sorry for the additional chicken scratch on it). #28 is the left and 29 is the right sensor. 28 wire is red with a black stripe and 29 is grey with a light blue stripe. I cut those wires and crimpped male/female weatherproof plugs on them as well as the respective wires on the efie. Now, if you sell your vehicle, just unplug the efie and plug the oem wires again retape and nobody knows. Put the plastic cover back on the plug, tape it back up and you're done.

I hope this can help someone.

Each time you reset the computer you may have to drive 200 miles or so for the comp. to relearn itself before you see any savings.

I agree. It should be a last resort, like hitting the reset button on your computer.
