Jeep Liberty Driving me Nuts!

[Squirrel]

I have a dry cell reactor
A tank with the three hose outputs and the cap mounted above the reactor
Big wires and relays
I've tried DC and using a PWM
Im using potassium hydroxide which can make the thing draw 45 amps if I want.
I have a MAP sensor "enhancer" installed (a potentiometer)

I get 17.4mpg from tank fulls, exactly what I got with none of this.
I believe in the technology (especially after flicking a lighter over the tank with the cap off) so besides nearly blowing myself up, what am I doing wrong? Any ideas?

Its as if the EICU has a minimum injector duty cycle dependant upon something other then the MAP....I dont get it.

Give us some more details. Year and engine specs. A description of your reactor like how many LPM your reactor is making at what amps, size etc. Pictures will be good too.

A MAP/MAF enhancer will help, but you haven't mentioned anything about altering the signals from the O2 sensors. Without an EFIE, the ECU will sense the additional oxygen & inject more gas.
As Carter mentioned, we need to know more about your vehicle & system.

Hey thanks for the quick responses guys!

Its a 3.7 liter 2003. Automatic 4wd, lifted with slightly larger tires (not important I'm sure).

Its a 7-element 5" dry cell from Ebay.
I dont know the LPM but it sends a steady stream of bubbles up the line to the tank.
I can get the current up to 45 amps but the wiring gets warm.
I ran 2 40 amp relays in parallel so the heat develops after that point (im considering bigger gauge if needed)
I have a PWM that I bought on Ebay where the groundplate of the reactor is seperated from ground on vibration isolators and the PWM completes the ground path.
I have the output of the tank injecting just on the engine side of the air filter (K&N replacement)
I have the MAP sensor installed and if I adjust it (up) the engine seems so hesitate for a second and then compensate quickly which fits with the statements about the O2 sensors.

So based on your replies I have these questions
1) EFIE? I've heard of these but a bit of a run-down would be good. (I thought the O2 feedback could only swing like 10% and the map overcame that but I guess this is wrong)
2) what can be done to the 02 sensors? (I think I have 4 of them)
3) Is there an easy way to measure LPM?

(love the democracy analogy)

First do you have a bubbler? If not do not use your system anymore until you add one!!!! You need a reservoir and then a bubbler. The reservoir can not double as a bubbler. Without a good bubbler you can do some damage that will cost $$$.

At 40 amps you are way over the limit for a 5x5. You need to keep that down to around 10 amps. .5 amps per square inch max of active area of one side of one plate. After subtracting the gasket area ports and dead area on the top you will have 20 square inches give or take a few.

Use the search feature and learn about bubblers, EFIE's, and how to measure the output etc. Lots of good info with pictures.

You will not need more than 1.75 LPM if that.

Before you go out and buy an EFIE make sure you know what kind the 2 front ones are. Narrow or Wide band. There are some very good EFIE's on the market but the good ones are not cheep. I would stay away from the cheap ones because they are a waste of money. The good digital EFIE's control all 4 O2's.

Sounds great, I was using a check-valve only so I'll take care of all those items and then gat back to you.


Thanks tons!

By "7 element" I'm sure you mean 7 plates (Damn Carter, ya didn't catch this?). This means it's (-NNNNN+). Adding another neutral plate would be much better.
Like Carter said, you can't run that reactor over 10 amps. It's active surface area is very small & you'll destroy the plates very quickly.
As he also mentioned, don't run without a good bubbler!!! I'll post a picture once again of what will happen very quickly to any aluminum parts if a good bubbler isn't used.
