Ok, I finally had a chance to sit down and configure the cabinet for Spyhunter and it did not work so great at first. Basically when I turned the SpyHunter steering wheel to the left, the white car turns quickly to the left, but when I turned it to the right the car slowly moved to the right. Seems like when I put the steering wheel assembly together the pot was not lined up correctly. It was adjusted to far to the left so when I wanted to go right, it barely went right. Anyway, that was a long explanation which basically gets me to my points....
unclet's point2: I had to remove the SpyHunter assembly from my cabinet to adjust the gear for the pot so I can now tell you that I am definitely using a 5K pot and not a 1K like you were wondering.
unclet's point1: For Pole Position and Spy Hunter, I use my "return to center" shifter with no problem to "shift" gears during gameplay. I push the shifter forward and it activates a switch but then goes back to center which then quickly deactivates the switch. If I had to use my Low/High "non-return to center" shifter then yes I would have to shift it into Low (activating the one switch) then move it manually back to High (to deactivate the one switch) and this would be a pain.
