After matching these spark settings I was able to use the trim box to adjust my spark angle until the commanded angle from the spark table
matched what I was reading on my pulley with a timing light.
The only issue I have now is in tunerstudio it shows up as the difference from the spark table to my trim. So at -12 on trim my 13 advance reads as 1 advance on the computer screen guage.
The reason I needed to do this is I welded my pulley in the wrong location.
