      T56 Magnum VSS question

      I'm using the VSS output from a T56 Magnum to provide shaft speed input to the traction control function of a FAST XFI computer. Anyone know off the top of their head how many pulses per revolution the Magnum VSS is? I've heard both 17 and 12, and wanted to be sure.



      Thank you....

      17 and 12 are both correct. 17 for the GM version, 12 for the Ford version.

      If I had to guess, I would say 17, but I do not know this 100%. Hopefully someone else will chime in with a definitive answer.
