i need some help on where to weld the new bung so i can put another o2 sensor on my 99 integra gsr for my air fuel ratio gauge... i have a defi d gauge air fuel gauge and they told me it was best to put in another o2 sensor on the pipe somewhere...help me on where to weld it close to? on the downpipe right? thanks

 

is it a wideband O2 your going to install?

 

18" from the turbo and before the cat is approiate for a wideband O2.

 

im going to try to just install it by adding another o2 sensor to my downpipe somewhere and then hook my gauge up to the new o2 sensor im welding a bung for

 

bump

someone verify this for me in my last post please...thanks

 

what the hell are you doing?
first off the Defi AFR gauge is a narrow band gauge, those are useless.
second, you certainly dont need a separate o2 sensor for that. just use the primary o2. adding another o2 wont have any advantages what so ever.

and if you must - yes 18" at least and before the cat. around the stock location is best.

 

which primary o2 sensor location would i use since mine is an obd2? thanks man

Primary O2 location.

 

Tap the wire into primary O2 wire that connects to the ecu... Like he said you dun need another O2 for a narrowband a/f guage, your car has one and second its a worthless guage

 

as said before is correct, anywhere is good, however in my turbo kits the prefered location is right after the turbo outlet right on the downpipe, the closest the best for accurate readings, remember if is too far you get delayed reaction and colder temperatures wich in time will reduce your O2 sensor life, O2 sensors like being really hot

 

put it anywhere you want because narrow bands are not even worth putting in.
