i got a jdm b16a sir II in a ej2 with a 3wire o2 sensor and i am n/a but i was manly wondering if a air fuel gauge is worth it? i have people tell me it is and isn't. i heard they dont read correctly either. i searched but couldn't find a stable answere. thanks!

 

Yeah, not worth the money.

 

oem sensors are narrow band thats why alot of people with modified engines get a wide band like a aem ugeo

i honestly wouldnt spend the money on a regualr air fuel gauge i would get a wideband

 

i was thinking bout the autometer A/F gauge. but ok i understand what you all mean now. guess i will just get a oil pressure, oil temp, and water temp gauge then. sence those are important too.

 

all you really need is oil pressure the rest are pretty useless unless you are doing some auto x or something

 

yeah i am going to be doing auto x. but i remember that my stock cluster has the oil temp gauge. so is there another handy gauge i should get?

 

(3-wire o2??)

stock cluster has water temp, not oil temperature
I would be more concerned with oil pressure...and really nothing else

 

oil pressure and I like having a good volt and or an amp gauge
