I'll do more correlation analysis on this log in Octave after dinner.


OK, here are some plots for:
commanded AFR = 15.06
RPMs increasing
Fuel system = OL

First pic has the x-axes all sync'd are time in seconds.

Second pic is just the bottom right 2 plots with the gaps taken out. X-axes are just samples, not time.

Is there a measured AFR limit of ~13.5 for CL?
