How the heck does the dyno get the wideband readings?

my autometer wideband gauge never shows me the same readings as my dyno sheet does.

my dyno sheet wideband readings look fine.

hwoever my wideband reading shows me too lean at wot on my wideband it shows 12-13 and then drops down to 11 for a split second (if i've let off) thers a big delay too ive only gone wide open throttle a few times..... so how do i know which one is more accurate?

i know they hooked up their standalone innovate wideband stuff in place of my autometer when tuning.. but aparently the tuner looks at both the innovate and whatever shows up on the dyno graph


so for cliff notes the question is

where does the dyno get its wideband readings? or how? also does anyone else's wideband have a delay? if i sit in park and hit the gas for a second like a quick rev. wideband wont do anything until ive already finished the quick rev.

Depending on the dyno and operator they may stick something in the tailpipe or put a wideband sensor directly into the exhaust if tuning.

It's really hard to say, one sensor could be old, bad or out of calibration and readings could be skewed due to that.
