Wideband installation
 

Hey guys, just wanted to find out where are you and how are you installing your widebands for tuning into your exhaust? Are you just welding in an extra bung?

Do the aftermarket exhaust for the SS/SC come with extra bungs? what about the vibrant headers since that is what he is looking at getting? Sorry, trying to help a friend research some data for his car and mods before he installs them.

Also, do you know if the GM S2 reflash does kind of what the MOPAR Stage kits do with eliminating the second O2 sensor (if the SS/SC has one). Just wondering if we could install the wideband in its place. Thanks.

Your going to have to install a new bung in the exhaust before the cat. The wideband kits usually come with the bung you need. It shouldn't cost you more then 40.00 at an exhaust shop to get it installed.

ya, its supposed to be about 18" from the head in supercharged apps. and like 36" in turbo apps. or something like that.

The GM tune does not disable the after-cat O2, that would make the car non-emissions legal, so they don't do it. You have to use HP Tuners or something to disable the second O2, I plan on using the second bung for my wideband to keep it simple, since my downpipe does not have a cat.

THe Wideband o2 must be installed before the cat so you cant just throw it in the 2nd o2 bung that came stock. it wont be an accurrate reading.

Umm, right. Thats why I have a downpipe with NO CAT.

Sorry, about the 2nd O2 sensor bung, forgot I am running an aftermarket DP. Mine came with 2 bungs both before the cat. Running a Needswings DP with Cat. My stock exhaust DP had the 2nd O2 sensor in the cat. Not after it. But I do understand that the wideband is supposed to be before the cat, if you have one, so that it gets an accurate reading.

get the LC1 which plugs into your first 02 bung (on the header) and simulates the narrow band and gives you your wideband.

way to awake a dead thread but at least i didnt open a new one hahaha. i am getting my wide band installed in to a local shop and i heard it need to be before that cat so i was gonna have them weld a bung in .

Where can I find instructions on how to use the LC-1 as a narrowband as well as the wideband?

The wide band is more accurate right ?

yes.

i have this setup.

How much more wiring is involved in doing this? I like the idea of getting a more accurate AFR reading by keeping the sensor close to the head.

you just have to fish through a wire for the narrowband signal and ground. Basically run it in parallel with the LC1 wire.

Sounds like I may go that route when installing my LC-1 then. Anything else special that needs to be done for that setup to work problem-free? I HATE going back to re-do something because it wasn't done right the first time.

just pm me if you have any questions about the wideband install i can explain it to you in lamens terms if you want , which is how i needed it explained

if you install it into the dp its got to be after the cat but before the bend , like i said pm me with questions

Ok, it may not be for a while, i won't be doing the install until I have my interceptors in my dual bezel, so maybe in 2 months or so. Thanks in advance.

k dont worry

here , you need to put your bung in the middle dot , thats probably the best spot IMO

That is so bang on. great pic. that is where I put mine.

just so you know I got my autometer wideband to work with HPTUNERS. works really well.

Is there a way to disable the first O2 sensor with HP Tuners, and just use that bung for a wideband? I just got my NGK wideband today, and dont want to have an extra bung. Im going to go aftermarket eventually anyway.

If I just disabled the CEL that would come up when there was no O2 sensor, and put my wideband in that bung, will it cause trouble?

You are talking about the O2 sensor in the manifold? You said the first one, just checking.

This helps ALOT! Now I can start to put this all together in my head how I'm gunna attack the gauges.

Yea, is there some way to take care of that with HP Tuners?
