1405 lean at WOT
I think I was making too big of changes, so I went (almost) back to my last known good tune:
095" primary
104" secondary (this is increased from a 101" I had in the past.
68x42 rods, silver springs
The vacuum readings here are 1-2" lower than what my analog gauge shows.
In this image, the first callout at 4:25 is moderate acceleration. At 4:35 I ease off a little, and the vacuum rises, and the rods go down, and afr leans out a bit. At 5:07, after coasting a bit, I go to WOT starting at ~50mph). It goes way lean, then stays pretty lean.
In this one, I go to wot from about 30mph. It spikes rich, then stays over 14 afr for the run.
I don't think I want to go richer on the power circuit. The wot readings just shouldn't be that much leaner, should they?
