I have a zex wet kit with the timing tuner but the timing tuner blinks back and forth between red and green which means the nitrius isnt hooked up right.Zex only has three wire a power. tps, and groung. I have the tuner connected to the power and ground. Are they not compatible together? If so what tuner could i use?

 

Zex is not the most user friendly to hook other units to. Ill have do do some looking and see if you can even use the two together.
