I'm looking for other members who are working on similar 4.0 trucks.

1. Mountaineer
2. Explorer
3. Ranger

To be able to trade results, ideas, & suggestions.

Thanx

I'm running a system in a '98 4.0 Explorer 4x4.
19 plate, 3 cell, 6x6 KOH

Tried dry cell, no improvement working on a titanium cell now.
Too much electronics to fool.
Better quality gas no electronics too fool.

I hear you. My Sport Trac is getting O2 sensor extenders, a MAF enhancer, PWM and if needed an EFIE.

This was easiier on my bug

Andy,
Don't bother with the O2 extenders. They really don't do much, and the EFIE will take care of the O2 signal. Also, be really careful with the MAF enhancer. Damned Fords don't like'em. Anything above 'barely turned on' will throw a bunch of codes at you.
Mine especially likes P0171 & P0174. It's also easy to set the burn too lean & could do alot of damage. You should install a EGT gauge & test the temp. before installing the electronics so you'll know if everything's O.K..

I've got my Scanguage installed just waiting to see what codes get thrown!
I'm looking at a Auto Meter 6445 Nexus. The PITA is drilling & tapping the sensor on the exhaust manifold.

I had a setup on my 74 beetle and it was sooo much easier w/o the electronics. I saw some decent MPG improvements. She went from 23mpg to 30. Thanks for the heads up!

Lee, (or anyone) ... chime in

I need a favor regarding the function of the MAF Enhancer vs EFIE. I understand the function of the MAF enhancer and how it affects the ECU but what exactly does the EFIE do and to what fuctions of the ecu? I know it is cut into the O2 sensors but how does it differ from the MAF enhancer's function?
From what I have read:

The oxygen sensor “tells” the computer what the oxygen content is by providing a voltage on it’s signal wire between 0 and 1 volt. 450 millivolts (.45 volts) means that the fuel/air mixture is correct. Higher values means the mix is rich (has too much gas), and lower voltages means the mix is lean. By adding voltage to the sensor’s output, we can compensate for the additional oxygen in the exhaust.
The Electronic Fuel Injection Enhancer (EFIE) does exactly this. It adds a floating voltage to the top of whatever the oxygen sensor is putting out. It has an adjustment that allows you to control, to within a few millivolts, the amount of this added voltage. This allows the computer to be unaware of the additional oxygen content of the exhaust from the HHO generator, and the electrolyzer can now achieve it’s full potential in fuel savings.

Isn't this the same function the MAF enhancer does?

If I am interpreting this correctly, I would say the EFIE would be the main controller while the MAF enhancer would be basically a "Fine Tuning" to the EFIE settings.
Would this be an accurate conclusion?

In order to install an EGT (EXHAUST GAS TEMP GAUGE METER) in my 2002 4.0 Ford truck would anyone know if this would require drilling the exhaust manifold or does Ford have a plug on the exhaust manifold?

Sweet,
I sincerely hope you do a bunch of research before spending good money on the 'specially coated' titanium cells.

[sweet7549]

Bench testing a wet mesh titanium cell.
Anode is coated 2 cathodes are not.
3.5 grams of KOH in 1 gallon distilled water.
Starting at 10 amps.
Ran 1 hour cell reaches 22 amps temp is 110.
Going to test all week.
Keep you all posted
Sweet!!!!!!!!!!!!!!!!
