why do wide bands display narrow also

[Mr overkill]

ok so im looking at all type of gauges


why does a wide band also show a a/f (narrow band) isnt the narrow band unreliable under high hp ???? Or am i thinking its narrow on the display and its really a wide (good) reading

I would say that looks like a wide reading. A narrowband won't show you 10:1 A/F on it like that one.

oh ok thats what i was thinking lolol thanks

[Whorse]

well I assume that's what the numbers by the lighting is for.

[BadAssPerformance]

Yep, it is a wideband.

that "0.89" reading on the gauge in the pic isn't narrowband. It's Lambda values. Stoich is 1.0 in Lambda and you have voltages either richer or leaner from there obviously. It's what the Wideband O2 puts out normally. The wideband controller takes this info and converts it to an actual AFR.

ahhhhh ok

yeah acording to fuel type
ex: gas 14.7=1.0=stoich

true. I left it out cause it I didn't think it was too important for what we do.

True, it really only applies to people running a wideband set to display lambda 1.0 as 14.7 with a fuel other than Gasoline, or people running alcohol injection.

There is a little bit of variance for gas with ethanol in it though. I was surprised when I saw the lambda chart that broke everything down when I got my gauge. I know it is not a huge difference, but it was enough to make me think.

Is this chart paper or electronic? I'd be interested in seeing how mcuh the ethanol mix used at the pump changes the stoich point.

It is paper. I thought about posting it, but I did not have the gumption yesterday. I might try to throw it up later.
