The advance goes up to 33.2, but it went as high as the mid 40's. It is so erratic, because it is hitting up against the rev limiter which I had set to 3600RPM. It uses a fuel cut algorithm, which is why it is so choppy. I need to get it running with less throttle, so I don't have to have it open 35%, then I can get a cleaner graph...but I'm just wondering if I need to beat back that advance first. --part1_21adb.5842042e.3b020be0_boundary Content-Type: text/html; charset="US-ASCII" Content-Transfer-Encoding: quoted-printable
