Msd Atomic trans controller

Has anyone used one of these controllers? I usually use the Compushift one, but in a budget mood and a deal I got the MSD one. Simple enough to program, but I get error codes on the TPS. I checked everything, and its correct. I use a Holley HP to control the engine, and bridged the gnd ref and 0-5 volts from the Holley to the MSD. I get errors on the TPS span and circuit. I tried 2 diff TPS's, even tried using the TPS by hand, so I would get the low/high volts, nothing I do makes it work. What little tech I found pretty much mimics what the book says to try. Strange it defaults to not using the TPS on orig setup, maybe I don't need it?
Thanks

Found a couple rev wires in the harness, swapped them at the end, all sync now and ready to go.
