Hi All. Newby question, but I have searched with no joy.
Wanting a definition for % A SPARK.
Think I'm in the right place, it's a TunerPro thing, and I'm after a definition.
From what I'm seeing, it's related to knock and timing advance, but % of what, and what's the 'A'?
Please delete in inappropriate, or wrong place. Or just put in a definition, and delete my waffle.
Thanks in advance
