Sweeet!



Bear with me here.

So if my WBO2 reads 'rich' (which is richer than 0.68 Lambda) at very high RPM's, over 6k and over 800 counts, but my STFT reads 0.85, which is what I'm commanding ... Then I should assume it's my timing that needs to be adjusted, correct?
Because firing the plug earlier would allow more burn time and bring the WBO2 back to where it should be.
Or am I thinking about this wrong?
