[Diy_efi]clarify: function generator for shutterwheel

[Phil]

some clarification about what I need to simulate the crank sig for VW ABA 
eng, OBD I ECM: a 60 cycle sequence with the last 2 cycles off; a  3V square 
wave is sufficient; and I need to be able to vary the frequency from 
6oo-7500Hz (individual square wave cycles)  ----- Original Message -----
