Ignition Timing

ChaseZ · 03-25-2017, 11:04 AM

This is going to be all over the place but should be able to get a sense of typical vs high etc. Been doing a bunch of short logs to slowly get this thing dialled in.

Most recently richened up the mixture so I wouldn't lean out too much right now at the top end while addressing some heat and other issues. I did a quick shakedown last night and noticed afterwards my ignition timing was 110*. I didn't even know that was possible... is something up?

Curious what others are seeing as I don't really have much of a baseline beyong recalling seeing numbers in the 40's and 50's before that I didn't terribly pay too much at attention to as the focus was elsewhere.

(Edit: I should add the AFR of 20 are because speed density hybrid tuning.)
