When we say 'timing pull' are we referring to the 'ignition timing cyl 1' section of the logs from the powertap air? I just started logging today, getting numbers as low as -22.something and am worried something is off. (If anyone could be generous and help me out with an explanation here it would be much appreciated as searching 'ignition timing' in the forum isn't coming up with much - I'm assuming timing pull is when this number goes negative.) Also hit -4.something knock on a couple cylinders but this cleared up with lowering boost on the 1.5 adjustable file. No idea what I'm doing so ended up switching boost down to 22PSI, octane 91 to stay safe, using Shell 93.
