quick air/fuel gauge question

[90_240sxx]

hi I'm installing an s14 sr20 into my s13 and i want to buy a air/fuel gauge but it says that it only WORKS FOR NARROW BAND OXYGEN SENSORS and i want to know if it will work the sr20 thanks

a/f gauges work with narrowband but the are more accurate with wideband. look into the aem uego

[IanS]

AFR gauges cannot except the signal from a wideband o2 sensor, but a narrow band o2 sensor is very accurate near 14.7/1 but there is very little signal change for large changes in AFR, this makes them very good for detecting rich and lean conditions but useless for telling you how rich or how lean which makes them useless in gauge form, for a widebang o2 to work with a gauge you need to have a wideband controler (UEGO controler) to convert the signal from a wideband to somthing the gauge can understand, but many good UEGO controlers have AFR readers already built into them so the gauge just becomes clutter

^^^ exactly..he took the time to thouroughly explain it Sideways do you have an aem uego wideband controller? if so where did you get it from just wondering if you know of the best price on the net

^^^^ i like and use the INNOVATE LM-1

ya ive heard good things about that one too

[IanS]

I run a Fuel Air Spark Technology (F.A.S.T) UEGO controler with built in gauge and data logger, they can support dual or single wideband inputs, they also have 3 differant output types to support any sort of external data logger/gauge/ECU, you can even use it in place of a stock EGO because the controler output can be configured to send narrow EGO signal instead of wide

[S13FASTBACKSR]

aems does not have a single AND dual wideband controller in one correct? you have to buy either or? And it also does not offer the 3 different output types for external stuff correct? So the f.a.s.t. uego controller blows aems out of the water?

[IanS]

yah, the single and dual use the same controler, you just get an extra o2 sensor with the dual, and the dual has the ability to either show both signals seperatly or average them together, here is the link, I run the single but all I would have to do to go dual would be just get another wideband o2

very cool...there is no point to run dual on a 4cylinder is there? or are there any circumstances that you would want to?

[IanS]

for people like us, no, unless you want to make sure your catalytic converter is working properly, or if you are running standalone on somthing like a horazontaly aposed 4 cylinder, its more of a benefit for V6s and V8s
