How many pulses per rev does the ECU output on a 92 spec Apexi? (Presume the same as the 92 spec FD...but I don\'t know what that is either!)
:confused: :wiggle
Anyone?
I\'m hoping its two pulses per rev....?
It will be the same for any 13B
This site had a good explanation:

but seems to be down for maintenance.
From memory, the rotor turns ar 1/3 shaft speed, but the rotors fire at 180 degrees of shaft rotation, as you have 3 events per rotor (3 faces), 2 rotors (because the apex and faces are offset by 120 degrees), but 1/3 the number due to gearing, giving 3*2/3 = 2
The other way to tell, is the CAS sensor has only 2 teath on the cog for firing events, the other sensor is for crank angle.
Cheers prof - you\'re awesome as always :)
