A friend and I are having the same problem with our Haltech E6K's.

When calibrating our throttle with the engine off, it calibrates just fine. 0-69 every time!

Once you start it up, it faults out! It reads 0 until about 2000 RPM and then starts???

 

check the wiring for cuts and fraying. make sure tps bracket is solidly mounted

 

Yeah... the 2 screws that hold my TPS on to the bracket were loose.

Somebody needs to mass produce TPS brackets!
