to show the cam angles is pretty impossible with available equipment that i have used, or seen to man on the street
as the timing is in constant varible, it is not dictated by any single imput., imputs to the ecu from inlet temp, engine load, throttle imput all give only part of the infomation to the ecu
i tried to get this info from TTE a few years ago, and there was nothing recorded that even they could get there hands on that showed any definitive scales or graph, to indicate some basic cam angle slope
