I've got the direct plug in C.A. with speedo.
What do I need to set the 'Set#Poles' to, for a MAC 500w (geared)?

Below is an excerpt from an email Paul (cellman) sent me about that very question. I'm now using an external shunt stand-alone CA and a wheel magnet with my Mac.
"The 12 fet should have a shunt resistance of approx 1mohm. The Mac has an effective pole count of 80 due to a 16 pole motor and a 5:1 gear reduction, but you should ideally use a wheel magnet when using a geared motor as it will not register distance correctly, when not under power, distance is not recorded."

Yep, use a wheel magnet with the CA sensor and set the pole setting on the CA to one.
May your tote always stay tight and your edge eversharp
