The PCS system 'Whip sells includes an output speed sensor solution on the output flange from which the VSS is derived. Once you tell the PCS what your rear ratio is you can then program a speedo output by inputting the pulses per mile expected by your speedo. PCS handles the math and you have a rock solid dead nuts accurate speedo. You can also do outputs v/s vss too.

Its a really sweet system and I don't even have the newer fancier one.


Beat me to it....LOL
