figuring out advance timing

@champyfz450
I can’t really add much to what @Mattax posted, he’s spot on. Quantifying your results will be the most difficult part of cruise tuning, and what you’re looking at will be mpg and “feel” which both aren't very quantifiable. Don’t worry too much about what your table looks like when you begin tuning. You can go back after the fact and smooth or interpolate the table and make it look better in the 3d model. Sharp spikes or dips are generally not what you’re after. I will say datalogging and overlaying the log on to the base map is the easiest way for me to see what is happening “right now” rather than tuning live. Don’t forget to go back and look at fueling after making timing changes in certain ranges, as both will affect each other.
