SP GT2.0 program card
 

Cant seem the get the program card to work.
When i plug it in the box turns on, but only has red dashes and no numbers.
No matter what i press , nothing.
Any ideas?

Are you certain the wire connecting the ESC to the box is 100% correct?

Make sure the negative, positive, and signal wires are matching the way the box is labeled.

If the speedo has a newer software on it the old basic program boxes don't work, for newer softwares you will need the LCD program box like this:
