Wideband O2

[crackedback]

Yeah I have the LM1 as well. Originally for the tail-pipe but I didn’t think that was a very accurate way to measure.

Sensor has to be deep in the tailpipe to get it away from any free air pulses.

As long as it's in the dirty air of the exhaust, preferably closer to the engine, it will read O2 content in stream. Check out where sensors are in new cars. Front ones are anywhere before the cat. If placement made a difference, the OEMs would be all over it. Collector, pipe right after reducer, won't make any difference with that placement.

Ok so I am new to wide band O2 measurements and using them to tune. Motor. Seems like I would need two channels for my duel exhaust set up. Right? Or at least two bungs one right one left for each side, then swap plug and sensor?

Yes.
