Speed cal help

[CobraFrenzy]

I recently installed a t56 into my 96 cobra. Bought the speed cal from Dallas mustang. I've doubl checked the wiring and all seems good. However my speedo only works when it wants to. Sometimes it seems to work great than anything over 60mph and it goes crazy. I have 315s and 410s. The code I have in now ( assuming that up switch is 1 and down is 0) 1001111110
any help would be great

If the speedo stops working intermittenly you probably have a bad connection. As far as the calibration goes, your best bet is calling them. I tried a ton of different codes and ended up calling them. They told me to drive a mile on the highway using the mile markers and call them back and they were able to get me a code right away that was pretty spot on. Not 100% but very close.
