l just got my engine back from kingtech for repair.. plug it all in an the gsu doesn't show the engine in the top left an if l go into the learn menu its black.. l have a spare set up cables no difference.. tried different gsu no change.. am l missing something.. plugged in a ecu from a k70. reads that fine.. shows throttle position low battery .. so l now the wire from the receiver works as well the gsu.. anyone else have this issue.. thanks
