Wheel_Notes

Calculating the numbers..

at 6000 RPM, CRANK wheel is turning at 100revs/sec, cam at 50

So for 4 cylinder distributor thats:
 2 pulses per revolution
 thus 200Hz.

6 cylinder distributor:
 3 pulses per crank revolution
  thus 300 hz

8 cylinder distributor:
 4 pulses per crank revolution
  thus 400 hz

60-2 crank wheel
 60 pulses per crank rev
 thus 6000 hz

60-2 crank wheel with cam
 60 pulses per crank rev
 thus 6000 hz

36-1 crank wheel with cam
 36 pulses per crank rev
 thus 3600 hz

4-1 crank wheel with cam
 4 pulses per crank rev
 thus 400 hz

8-1 crank wheel with cam
 8 pulses per crank rev
 thus 800 hz

6-1 crank wheel with cam
 6 pulses per crank rev
 thus 600 hz

12-1 crank wheel with cam
 12 pulses per crank rev
 thus 1200 hz

40-1 crank wheel with cam
 40 pulses per crank rev
 thus 4000 hz

disty four style 50 off 40 on
 2 pulses per crank rev (4 per cam)
 thus 200 hz

oddfire 90 0,135
 odd pattern, thus no constant freq portion

Optispark 360 and 8
 360 pulses per cam rev, thus 180 pulses per crank rev
 thus 18000 hz
 NOTE: max rpm about 15krpm MAX with this pattern before ISR overload...
 Sweeping on this one may have jitter issues too

12-3 oddball
 12 pulses per rev
 thus 1200 hz

36-2-2-2 
 36 pulses per rev
 thus 3600 hz

4200 wheel
 odd pattern, thus no constant freq portion

36-1 mazda FE
 36 pulses per rev
 thus 3600 hz

mitsu 6G72 with cam
 3 pulses per rev (crank)
 thus 300 hz

Buell oddfire
 4 pulses per rev (crank)
 thus 400 hz

GM LS1
 Odd pattern thus no constant freq portion

Lotus 36-1-1-1-1 oddball
 36 pulses per crank
 3600 hz

Honda RC51 wiht cam
 12 crank pulses
 1200 hz

36-1 with zecond trigger on 33-34
 36 crank pulses
 3600 hz

36+2-2 NGC4
 36 crank pulses
 3600 hz

Weber marelli 8 crank 2 cam pulses
 8 crank pulses 
 800 hz

Fiat 1.8 16V
 Odd pattern

Nissan 360 CAM wheel sensor
 360 cma teeth (180 crank equivalent)
 18000 hz
 NOTE: RPM limited to about 15K rpm
 Sweeping may introduce some jitter

Mazda 24-2 caz (equal to 12-1 crank)
 12 crank teeth
 1200 hz
