Wideband Efie

[hygear]

Hi,
New to the forum,but not to hho generator construction or tuning mods.I've built several cells and done all the mods possible to my 05 Dodge Ram 1500 5.7 Hemi 4x4.
I'm wondering if anyone has located a source that sells wideband efie's.This is the last thing I can install on my truck to further my mileage gains using an hho generator install.I have a large tero cell design installed presently that has an output of around 4 LPM.
This forum seems to lean towards sensor and leaning mods,so I hope I might find someone that has located an efie that is compatable with wideband sensors.
Any help with this would be greatly appreciated,and also anyone needing help or advice regarding cell construction I'd more than willing to help.

Thanks HYGEAR

Your ram has wideband sensors? Does it have the california emissions package or is the hemi that different from my 06 4.7 ?

I'm not sure about the calif. emissions package if they're wideband or not.I'm starting to think the hemi is in a class by itself,and I'm also not sure if calif. package is the same for your 4.7.Have you checked your voltages to detemine what type sensors you have?If it's like mine you should be reading around 7vdc for the heater wire and 2.5 to 3.5vdc on the other two(the fourth wire is the ground)remaining wires.Any voltage over 1 volt with the exception of the one that powers the heater which would read around 12vdc if it's a narrowband will most likely be wideband.These are the voltages for my vehicle and may vary from others.

Ok, if you have one o2 pre-cat and one o2 after, then it's not cali emissions. I was under the impression that my o2 was a narrowband, just from what I've read, I'll have to get under there and hook in a voltmeter.

I just dove into my 2006 dodge ram workshop and service manual, it states under the emission section that the o2 sensor will send a signal to the ECM that is between 0 and 1 volts, this is definitely narrowband. Not sure why you are finding a wideband in yours?

I take it you allowed the o2 time to warm up before reading?

I checked voltages with just ignition on,with the engine running (but not fully warmed up) and with motor running at full temp.Same results with little variance with each of the readings,also checked both precat sensors just to be certain.Yep it's wideband alright,also have friends on other forums with the same year truck and motor,all have widebands some 04's as well.Does your truck have 1 precat and 1 postcat or is it like mine with 2 pre and 2 post?
At least you have good news being yours is narrowband,the 0-1 volts confirms that.It may be that they installed narrowband on the smaller motor for some reason.
Afr's are apparently tricky to get around,if not you would see them listed on flea-bay and numerous other sites selling hho wares.I'm not the only one searching for these,a lot of people are waiting for someone to develop one that works.Until then I'm stuck with my modest 14-15% increase with hho and other mods I've installed.
