Cam sensor

Well started thinking about other sources of a signal and the camshaft sensor (inlet cam I'm assuming given it's position on the rear face of the head) isn't such a bad candidate. Appears to be a 6VPP sinusoidal signal with varying dwell of course with engine speed. Pins are easily accessible near the BMSK (twisted Blue/White and White pair) so this seems like a better solution that using the COP feeds IMO - no cutout going down hills. Obviously it isn't really a VSS because it only samples engine speed not road speed, but most of my cruising will be in top cog so good enough for me. See pic below, timebase is 1ms/div and 1V/div vertically. Cheers KP
