This page is about crank trigger, which is a 60-2 teeth wheel, VR, stock


Measured data from BengtR:

Crankshaft angular speed/position ie. VR Sensor -> 60-2 wheel info...

60-2 wheel diameter 215 mm, tooth width 4.5 mm, space between adjacent tooths 7 mm.

Sensor / TDC position is 165 mm from 1st teeth rising edge.

TDC is 15nth teeth falling edge = approximately 88 degrees after 1st teeth rising edge.

Same mathematically...

diam 215 mm x pi -> 675.44 mm

675.44 mm / 360 degrees = 1.876229 mm/deg.

165 mm / 1.876229 mm/deg = 87.94 degrees.

or

15 x 4.5 mm + 14 x 7 mm = 67.5 mm + 98 mm = 165.5 mm

165.5 mm / 1.876229 mm/deg = 88.2 degrees.

TDC = 88 degrees after 1st tooth rising edge.
