Help understanding timing numbers in megatune
Posted: Tue Jan 04, 2005 12:02 pm
Does 35 degrees advance in megatune means 35 degrees BTDC, or 5 degrees BTDC??? What about 5 degrees in metatune, is it 5 degrees BTDC or 25 degrees ATDC??? What I tune on computer and engine response does not make any sense. It takes 45 degrees of megatune's advance before I see pinging at 3000 rpm.
