Thanks to everyone for their input my lean AFR readings after extended trips. It is just scary to see such a jump.


911st is right - your engine is on the 'over-run' (i.e. lift off the throttle)

Here's mine (with Boost in Red):

When the black line (RPM) dips, the blue line (AFR) rises.

Here's a smoothed version of the same picture:

There's a lot of noise on the Boost signal. (Trying to find ways to reduce this.)
