Looking for a known good cam/ crank waveform for a 2008 Equinox 3.6 VIN 7. Inherited from another shop that swears timing chain is timed correctly. Trying to confirm reluctor did not move on crank . 

I have attached waveform of both intake and B1 exh with crank.( First 2 pics) I only have 4 channels so I will upload both exhaust , B1 intake and crank shortly ( Last 3 Pics)

The codes that you are giving are telling you there is a timing issue. There is a tsb on the crank reluctor moving .

I seen that , trying to compare to known good waveform to confirm. This is AWD so only option to inspect crank is to remove Transfer case or oil pan

David; Good afternoon I hope this message finds you doing well. Attached is an Engine Mapping Article I wrote around GM's 3.6 Liter from a 2008 Saturn Aura VIN 7. I hope this article helps
