Okay so I need some help. I have two vehicles at home with the Duratec 35. One is my 13 Edge, the other is my Dads 17 Explorer. I am trying to see the timing benefit of 93 octane in my Edge vs 87 octane in his Explorer.
Using FORSCAN to look at timing, how come I am seeing negative intake timing values in degrees? Shouldnt it be a positive number?
Like negative 30,degrees timing. Shouldnt it be a positive number? Exhaust timing shows a positive number
