Throttle body sync guages

You asked for that one.....................

Bull......I would slam a screen door that hard

Yes, the MAP sensor uses the crank sensor to determine which cylinder it's reading - the MAP sensor is fast enough to detect the difference in pressure between each cylinder;
Related - there is no cam position sensor - ever wonder how your Triumph knows which stroke to fire on?
The ECU also uses the MAP to determine which is the intake stroke (and hence determines the timing for firing)
On Triumphs, old, old systems (Sagem gen1)* had a cam sensor to determine the cam vs crank position; old systems (Sagem gen 2) used a cranks sensor with multiple teeth that actually determined the different rate of acceleration for the power stroke to determine which strike it was on. But the Keihin system uses the MAP sensor to determine which stroke to fire on

When I come see you on Monday, please have the IV kit prepared!
I wish to hook up and drain some of your smarts into me.
