Wideband O2 sensor options

[wheelieking]

I've been using an MTX-L Plus for a few months now after my AEM gauge and sensor died (I think it was the sensor, but did not dig too deep).  It goes through a "heating" cycle for maybe 15-30 seconds when you first start the car which is supposed to be good for... stuff.  I guess I can't speak to its longevity just yet though.    I'm also using their cool little pocket data logger to try get a handle on my weber 38/38, and to teach my 10yo  about AFRs... and fractions... and analytics... LOL.  

 

(BTW. Yes, those are brief 22:1 AFRs right off idle.  Aka the off idle stumble is strong in this one right now. )

Is it the MTX-L or anoter Innovate? The others are reportedly ok, but the MTX-L is really bad from my (repeated) experience.

Not sure off the top of my head but I will check and report back.

The angle of the sensor bung in the exhaust pipe for one.  (needs to have the tip angled down).

Thanks all for the replies, holidays have delayed me from responding. 

 

@Mark92131 Trying to understand. Are you saying the bung needs to be welded to the exhaust pipe at an angle rather than perpendicular to the long axis of the pipe, or the top of the pipe (underbody side) vs bottom (road side of the pipe)?

 

I purchased an exhaust system with bung attached from ACP Headers who took over for Stahl, so guessing it is done correctly but trying to understand the concept. 

 

Again, thanks all for the replies and happy holidays

Here's the recommended installation for the bung.

Yes, the manufacturers recommend at least a 10 degree angle to prevent condensation build-up on the tip of the sensor which can reduce the life of the OS sensor.  See attached.
