Im getting a used aem uego wb, so Im guessing instructions wont be included. I just wanted to know for anyone with this, how far from the head does aem say to put the sensor. Im also redoing my exhaust and have a bill and stans header/ downpipe which is ceramic; whats needed before I weld the bung on? Should I grind the coating down?
Sorry if this should be in tuning, its not soo much questions about afr's or anything like that so thought it'd be fine here.
12-16 inches from the head at an angle.. Have the stock sensor about an inch, inch and a half down from that(not inline with the wb though)
Yes, grind down coating before welding I believe.

umm....forced induction or NA?
they have 2 different specs.
forced induction goes further down the pipe. i have the sheet at home, i will look up the 2 specs, but i believe both of them are greater than what was posted above.

Thats why I keep my registry updated
Sorry not trying to be a dick, but Im sc'd.
And thanks whitecavy. I dont have a rear o2 sensor and Im using a caspers sim, maybe Ill take care of that soon with hpt
you should know i am so used to people not even filling that out, I rarely check....so kudos for that.
i believe they say it is 24" downstream, but i will verify that later.
and you will have to grind to bare metal to weld.
A weld-in M18 X 1.5 boss is supplied for sensor installation. Mount the O2 sensor in the
exhaust system at least 18 inches downstream from the exhaust port. If you anticipate
high EGT's (over 800C), run a turbocharger, run at high RPM for extended periods of
time or plan on running leaded race fuel then you must mount the sensor at least 36
inches or more downstream of the exhaust port as all of these can cause the sensor to
overheat. On turbocharged engines the UEGO sensor must be installed after the
turbo charger, if not, the pressure differential will greatly affect the accuracy of
the unit. For accurate readings, the sensor must be mounted before catalytic
converters and/or auxiliary air pumps. To prevent collection of liquids between the
sensor housing and sensor element during the cold start phase, the installation angle
should be inclined at least 10° from horizontal with the electrical connection upwards,
see below. (Figure 8)
