On the trinity under knock retard there is a smaller window
Bottom. Looks like. 00/00
Is the numbers on the left side that show in negative timing being added and the right
in positive a knock?
Example. -25/.50 Is this 1/4 deg timing added along with 1/2 deg retard or knock?
Lol hope I asked this correctly
thanks.

-25 would be pulling 25 degrees. .50 would be adding .5 degrees.
