Testing air fuel ratios

[dylanjen9]

Is there any way to test AF ratios without getting a wideband kit and welding in O2 sensor? Just want to set mixture for running nitrous

Nothing I am aware of... have to have an 02 sensor and a wide-band to read the sensor.

I just wanted to know if there was something I could put down exhaust pipe just to see what mine was reading. Dont want to punt another gauge on sled

Even if you did that, you would only be measuring it at idle. That will help you straighten out your idle if you are having idle issues as are most on the 2015 flash. It will do nothing at WOT where you really care as to not lean out and burn up your engine...

If you can find an old school auto shop that has an old Sun Engine Analyzer. This had an exhaust probe that we used to set the A/F at idle. I'm sure you could get readings off idle as well.
