I understand that the stock VSS generated 2K pulses per mile. However, my questions are as follows:
i.) are the pulses analog or digital (sine wave versus square wave)? and
ii.) are the pulses 5V or 12V (or something else)?
Background: I am looking at making a 3d printed piece (I will likely be using Taulmann 910 for the 3D material) that uses plastic bolts to bolt it around the outside of the drive shaft (near the transmission tailstock). I have removed the ECM for controlling the original EM4E carb and distributor. Carb was replaced with mountain man qjet and HEI with vac and mechanical advance.
I would like to get my cruise control working again using the signal from the 3d printed piece with steel (or perhaps neo magnets) imbedded in it. My understanding is if I use a hall effect switch (generally three wires) then I will get a square wave. Alternatively, if I use a variable reluctance sensor (two wires) then I will get a sine wave.
PS I am aware that I can use the existing speedo cable, speedo, optical sensor and buffer to fix this problem also.
