Could you be a little more specific? Have you done anything to the car before things stopped working?! You might also want to check out the engine management section.

Did you set it to peak mode? This is where it only shows the highest readings and anything less won't be displayed on the screen. If the tach shows a rpm reading of say 2500 rpm rev it to 3 grand and the number should raise. What is the commander reading?
