About the only way is to use a scan tool and an oscilloscope on the cam and crank sensors and watch the wave forms move as you cycle the cam phasing with the scan tool. Then you could see if IATN or Pico have a good known waveform to compare it.

Looking for the color of the three wires for coil 1, 2, 3, 4. Do you have that? Changed the ECM but need this before I connect temperature sensor. Thanks in advance.
