Are you sure the dash uses RPM pulse input?
Newer cars have switched over to CAN bus or a similar system. So they don't use an RPM signal directly. Instead, the data is sent over a serial connection running throughout the entire vehicle.
Sadly, if this is the case with your dashboard, the RevBurner cannot drive it. Unless you find a way to emulate the serial bus used by Ford, I doubt you can make it work without swapping out the internals of the instruments.
As to why Christiano can drive his yet you can't, this could be explained by a refresh. Manufacturers update their products throughout their lifetime, so this revision of the dash could be newer then Christiano's.
