The stock logging options should be fine for the AP. But double check with the Cobb youtube video on "Logging with your AP" or something similar to that name.
OK I thought there was something specific you wanted me to log. I will get a log up on my way from class later today and am going to swing my a parts store to get a compression tested since the little nipple on mine died a few weeks ago.
(almost cost a buddy his motor too, though he had low compression then found out my gauge couldn't hold compression any more)
