LMR (Late Model Racecraft) Wideband o2 Sensor Location?
I see a pipe welded to a jackstand with an o2 sensor portruding out the side which is inserted into the tailpipe of vehicle.
Anyone else seen or used o2 sensor in pipe sticking out rear exhaust location?
I always thought it normal procedure to remove (1) front o2 sensor
or
Install seperate dedicated o2 bung before catyltic converter for dyno testing

NOTE: NOT A CALLOUT. MY QUESTION IS FOR EDUCATIONAL PURPOSES!
In my opinion LMR is the king when it comes to LSx tuning.

The folks on Hp Tuners forum in genereal typically frown on a tailpipe clamp o2 sensor.
This looks like a custom made tailpipe setup with the same premise.
Again it obviously works (LMR ain't no second hand shop)!
I understand as a general rule you would have to compensate approximatley +.2 AFR if the vehicle has catalytic converters.
Just wondering what LMR's among others thoughts were...

Yes, on most street applications(500hp) we use the wideband in the tailpipe. For forced induction/nitrous cars making big power, we use one after the headers collector and another out the tailpipe just to be safe. As always, we road test vehicles to check A/F readings. Hope that helps.
