On turbo cars it is recomended further down stream like Jason said...end of the DP or in the test pipe. If mounted closer Innovate recomends a heat shield or heat sink...no less then 10" from the turbo. Also should be mounted anywhere from 9 O'clock to 3 O'clock...not on the bottom.
From the Innovate Mortorsports LM-1 manual...
3. Installation
3.1. Mounting the sensor using a Bung or Exhaust Clamp.
Using a bung is the preferred method for mounting the O2 sensor for both catalytic and non-catalytic cars.
On CATALYTIC CONVERTER equipped vehicles:
Bung: Install the oxygen sensor’s bung upstream from the catalytic converter
(a bung and plug is included in the LM-1 kit). Any decent muffler or
exhaust shop can do this for you. The wide-band 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.
……or………
Exhaust Clamp: You may use the optional Exhaust Clamp to mount the O2 sensor to the
car’s tail pipe when taking readings from cars with catalytic converters
(see below). However, it is recommended instead to use the bung (as
described above) to give you the most accurate reading. Measuring
after the cat will result in leaner-than-reality readings, depending on theefficiency of the cat. Some operators of chassis dynos use this method
and roughly “correct” the reading.
On NON-CATALYTIC converter vehicles:
Exhaust Clamp: With non-cat cars, you can simply take the reading from the car’s tailpipe; however, you MUST use the optional Exhaust Clamp to do so. DoNOT simply insert the O2 sensor into the tail pipe. Doing so may
damage the sensor and it will certainly not yield accurate
measurements. (The oxygen sensor needs to have its cable exposed
to outside air to yield the most accurate results.)
……or………
Bung: You have the option with non-catalytic cars to also use a Bung as
described above. Use of a bung is the preferred method for mounting
the 02 sensor for both catalytic and non-catalytic cars.
On TURBO CHARGED vehicles:
Bung: 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.
