looking for help... i run a T56 (rotary) in my FD and have a Dakota Digital module to convert the trans digital signal to the dash speedo.

which now works accurately to 60 mph and then the speedo goes to zero.

any ideas as to what is happening?

thanks,

How do yo have it wired up right now? We've definitely got a lot of people running that exact combo.

 

The 2 wires from transmission speedometer gear go to DD (signal and signal ground) output wire is split with 2 wires out of DD to x14 plug, and ECU. The DD is power and grounded.

 

The only thing different from most I've seen is that we usually split before the DD, not after.

Could it possibly need a pull up resistor?
