My question is, can I use my driver side upstream 02 sensor location for my a/f gauge?
I do not have any cats, and my check engine light as been tuned out my the previous owner.
will it create a new code and throw a check engine light?
also, is the driver side upstream o2 sensor is in between the 3-9 o-clock positions to keep condensation out of the sensor?
I am looking at the aem eletronics x series wideband gauge.
Or should I obviously take the time to cut and weld a bung on...
Anyone have a good install video I can follow??
 
I vote for a new bung hole.

Oh... My goodness.

It's like shooting fish in a barrel sometimes. :rlaugh:

Yes. You need to get a bung welded in. Clock the sensor on the pipe so that it's not hit by any condensed water in the exhaust.
