I'm having trouble getting my VSS to read correctly. There is a thread a few below this that I was looking at, but when I tried doing some of the math, it was way off.
This is my setup:

2001 5.3 in a Foxbody
I'm using the Ford T-5 with a 23 tooth gear for the speedometer
Dakota Digital 8K PPM VSS converter
4.10 gears
245/50/16 rear tire

I'd like for the PCM to see similar MPH as what I'm travelling, but just can't seem to find the right combination. Any help would be great.
