Sorry didn’t get a pic, but bank1 started about 4 notches into the 10 notch pattern in the crank, and bank2 was 3 notches in. i’m not sure where the zero point should be or what the expected timing at idle is. Will get a pic tomorrow.

Thanks for the links. The car won't fire with both unplugged even after clearing and resetting everything.

I borrowed a friend's working G37 for a few minutes and got these traces of camshaft bank 1 vs bank 2

I think this seems to confirm that my timing is in fact off somehow, so I'll have to open it up.
