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

|
|
thus 300 hz
|
|
