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

Did they send back the right ECU? Check your serial number on the back. Sounds like and ECU issue.

yes it the correct ecu..I've had this happen before.. but last time the ecu was wiped.. unit was reprogrammed an sent back.. not sure why it has happen unless it was by a magnetic or xrayed.. have no idea

Its sounds like they did not check their work when they were done with it. I would not be surprised if they update all the ECU when they pass through and yours got wiped but was not re-written . Call and ask , but I would be you have to send it back in.
