Sup guys,

Does anyone know for a fact that the Defi Dgauge series AFR gauge can or can not be used w/ our cars.

TIA

 

The defi gauge is a not a wideband AFR, yes it can be used, but it would be a waste.

Get the innovate, zeitronix, AEM, or PLX wideband

 

so it can be used but it wouldn't be accurate or what? Basically i'm looking for a uniform look as well as function. My car is a bit of a show car as well so I wanna have the same gauges if possible. Thanks Ziv, you've been very helpful.

 

the defi is a narrowband, and kind of only gives you a general direction of where you AFRs are. Look into the Innovate wideband with the black face.

Check out this vid and you can see the innovate setup in action:

Anyone know if the Autometer Nexus AFR gauge is wideband?

 

nexus isnt. its the same as my friends jacksonracing autmeter AF gauge.you tap into your stock sensor, so you can only tell stoich when your at full throttle

 

Summit racing says that the kit includes a sending unit, but they couldn't give me any more info than that. I'm waiting on a reply from Autometer.

 

thanks again guys. Yeah actually considering the Zeitronix and have it do boost as well and call it a day. Only downside is it'd be hidden and therefore no show points when I do shows.

 

I don´t quite understand. Does that mean that the defi d gauge will only tell you for instance, 11 or 12, or whole numbers, whereas the wideband would tell you 11.7 for instance. Or does it mean that when the gaude reading is 11, it really means it could be anywhere between 10 and 12. Also, surely if you have your car tuned well, you would only need a narrowband, to keep an eye on things?

 

narrowband is very hard to read because it wont be a steady pulse. your gage would flctuating form lean all the way to rich really fast and you cant learn from it. only could tell what the engine is doing by buying a wideband or narrowband at full throttleis where you can tell. but other than full throttle research its useless

 

so your basically saying that, wether you get a narrowband or wideband, it will only "really" read at wide open throttle? Well that´s just fuking pointless then isn´t it. You´ll only need it when your tuning. I still don´t understand about the narrowband AFR. If its so unpredictable and crap, why do they make it?

 

Because it's cheaper.

 

I´m sorry, but for a hundred bucks difference i don´t think thats the main reason. Also, if you were to plug a wideband sensor into your exhaust and wire that up to the defi gauge, then wouldn´t the defi gauge then become wideband. Surely its the sensor that has to be accurate, not the gauge?

 

hey buddy wideband you will be able to see during any given throttle postion. sorry for the confusion narrowband is absolutly worthless unless WOT tuning like nitrous tuning. wideband is a must for FI applications. let me grab a video of the narrowband gauge for you guys perhaps you will enjoy seeing how it works! ill post it tonight or early tomorrow!

 

ok then. lets see if i´ve got this straight (forgive me for being so thick). A narrowband will be accurate, but only at WOT, and anything less than that, its a bit iffy. But the wideband is good all the way through. And with regards to my previous reply, can you stick a wideband sensor on a narrow band gauge?

 

exactly narrowband shows at WOT perfectly whats going on, but if your not at WOT then the gauge sweeps to often to interpret it. it just sweeps from lean to rich in its modes cause it cant read the inputs. only at wot where its constant. with a defi gauge on wideband youll be able to see everything thats going on at everygiving point accuratly. i dont think you can use a narrowband gauge on wideband because the sweep is incapable of handling the huge range of a wideband. especially like autometer gauges whos sweet is not very incramented. i would recomend either zetronix or AEM. i personally trust AEM but thats just me! ill def get you a video.

 

Has anybody else got any more opinions? I´m very interested in this

 

Got a response from Autometer for those interested, sorry for threadjacking btw.

 

Thanks for all the great response. Learning alot.

 

Dang show cars...
