could you look at my log - map 2 93 octane. -

afr looks ok to me but the ignition timing looks odd number one looks like actual timing and 2-6 looks like ignition changes but i dont know if it
is positive or negative.

Not pro but my thoughts.

Yes ign1 is actual timing advance and ign2-6 is amount of timing advance being pulled. So if you take ign1 and add ign2-6 (biggest loss cylinder, just one of them) you get what it wanted for timing advance at that rpm, load, ect.

For map2 looks like you are using a low octane fuel. Timings not crazy bad like 4,5+ but generally are better at that boost level.

on the another thread they said to not shoot for 0 because you are leaving power on the table
just topped it off with 93. do you feel it would be safe or should i go back to map 1 until the next tank?

thanks for the input

Seems fine for pump gas on map2. They are stable longer term timing corrections.
