Im adding a AFR gauge to my 2002 dodge ram 1500 3.7l and was wondering how i konw what band the o2 sensor is......Any info would be appreaciated....ive been told its a narrowband but i want to make sure cause if it is i can wire it into the sensor and if not i have to spend 222.00 on a wideband kit.....so yeah thanks

 

What AFR setup are you using? Stock O2s are narrow band and usually wideband O2s come with the AFR kit you are buying.

An Innovate LC-1 wideband will run you about 150 new (cheaper used)

 

Don't waste your time hooking up a gauge to a stock sensor.

 

Im wanting to run a narrowband system.....i dont want to spend alot of money i just want to see where im at. Also i had a friend of mine tell me i could hook it into my stock 02 sensor and be fine.....but hes gone through 2 trucks from moding them himself so im a little paranoid about doing so i just want somebody elses opinion on if it could be done or not.

 

What exactly are you trying to do and accomplish? What equipment or setup do you have already?

 

Ok, i got my gauge in and its working fine...im just wondering if it will mess with anything else in my truck...ie: telling the computer to put more or less fuel into the injection or anything like that. it dosent seem to be but like i said before im a little paranoid. i wouldnt think itd mess with anything but some opinions would be nice. THANKS!!!!

 

I gauge is only a readout device and nothing more. But again, what is it you are trying to do overall?

 

i just want the look of it im not trying to fine tune anything
