Default AFR on my Downpipe

About to get my down pipe on. My question is, should I wait to get the afr so I can do the bung then, or should I put the DP on and then once I get the AFR install the bung. Can they install the bung with the dp on the car?

It is much easier to weld a bung with the DP off the car especially if you aren't the one doing it. I'd charge you less if it was off the car. I'd wait. Yes they can weld the bung off the car if you are installing it near the stock bung. It just depends on where you want the bung. This is what innovate recommends.

Install the oxygen sensor’s bung upstream from the catalytic converter (a bung and plug is
included in the LC-1 kit). Any decent muffler or exhaust shop can do this for you. The wideband oxygen sensor is then installed into the bung to take a reading. (Insert the plug into the
bung when not in use). The bung must be installed in the exhaust pipe at the side or on
top, NOT on the bottom of the exhaust pipe. Best position is between 10:00 and 2:00
position.

On TURBO CHARGED vehicles:
Install the bung downstream from the turbo before the catalytic converter. The high exhaust
pressure before the turbo interferes with the lambda measurement and the high exhaust
temperatures encountered there can damage the sensor.

Do NOT install the Bung below the 3 o'clock or 9 o'clock position.
Condensation can form in the exhaust pipe and permanently damage the sensor.
6 o’clock is the absolute worst position to mount the sensor.

Wide band oxygen sensors – like the one shipped optionally with the LC-1
– are designed to work with unleaded gasoline. Using them with leaded gasoline
will significantly reduce the lifespan of the sensor. The reduction is directly
proportional to the metal content of the fuel. In most cases, a wide band sensor
will provide accurate measurements somewhere between 50 hours and 500 hours
with leaded fuel.

WHEN INSTALLED IN THE EXHAUST, THE OXYGEN SENSOR
MUST BE CONNECTED AND OPERATING WITH THE LC-1
WHENEVER THE CAR IS RUNNING. AN UN-POWERED OXYGEN
SENSOR WILL BE DAMAGED WHEN EXPOSED TO EXHAUST GAS.

you can find a plug at most auto parts stores, look by where they sell oil pan drain plugs. some spark plugs will also fit

yeah they make plugs for the bung or you can go to the hardware store and get a bolt or pipe plug that is the correct thread pitch. Most are 18mmx1.50. I also found one at a local auto parts store but when I returned again to buy another one they acted like they never heard of one lol. Online they are sold here http://www.o2bungs.com/


Also Google is your friend . I just happened to no be busy. Good luck!

You should have waited til you got your gauge in to do your bung. The kit comes with a o2 bung

There are lots of places to wire it up. Most people play it safe and use a fuse tap for the power source. I have my gauge spliced into my clock harness and grounded on the radio head unit. You only need two wires, black (ground) and red (12v ignition switched). The other two won't be used.

Here's how it looks:

It can be done. I actually had the bung welded onto my downpipe after it was installed.. It was a pain in the hell and had to be a lot more careful, it its doable.

I'd prolly just had the bung put on before you install it on the car and just cap it off if you're not ready to use it.
