Dakota Digital Speed Settings

I have installed the

$114 Dakota Digital SGI-100BT Universal Speedometer and Tachometer Interface

Dakota Digital SGI-100BT. Have not figured out the specifics on the settings, specifically via the App.
I went with High/High for Application 1. There is an option for a pull up(resistor). And a Low or High Input. Also has frequency settings.
Best I can get is the Speedo is either bottomed out regardless of speed, or it is stuck at fixed points depending on the frequency. 33Hz brings it to ~30mph, increasing the frequency increases the speedo. Have tried Output 1 and 2 as the manual suggests and others on TQ have mentioned. The manual also has reference to the other outputs which appear to attenuate the signal.
Anyone have experience with these specifics?

 

I can't really help you with settings but I can tell you that the speed input to the Combination Meter (Instrument Cluster) is a 12v pull down design circuit, the Combination Meter supplies 12v on the SP1 terminal and the Skid Control ECU (ABS Module) (A/T & 2012+ M/T) or Vehicle Speed Sensor (05-11 M/T) pulses it to ground to generate the vehicle speed signal.

 

Unit is working. I had a wire landed in the wrong spot. Also was unclear on how the app was responding. Ended up with the default settings, High/High. But used the actual module buttons to tune the speedo based of GPS. Verified accuracy at several speeds and all is linear!
I also replaced my clock spring and CC stalk at the same time since CC has not been working.
I have an apparent glitch from the Dakota module where the speedo will briefly dip and causes some throttle issue when in cruise control. Others have reported similar.
