Compression test results:

Cylinder 4: 160
Cylinder 5: 150
Cylinder 6: 160

Other bank is more of the same. Waiting on the weather to improve before logging the revised fueling.

im going to have to agree with prj, the cats could be an issue, if you really want to test it a simple backpressure gauge from your local parts store in the o2 port will give you some insight

here is the type of gauge i typically use in the shop here

I understand what you're saying, but the cats are 2 months old. They're coming off on the next nice day, so we'll see.

It doesn't matter how old they are. If they are bog standard ceramic cats it's not gonna work, as they are gonna restrict too much.

Alright, I'm bumping this. Problem never really solved, sorta just put it on the back burner. I started logging cam changeover, and this is where it gets weird. I haven't touched it in the file, so the cams SHOULD be changing state. They're not. Never advancing. What's more, bank 2 starts to show deflection when you get closer to redline. Log attached, as well as a picture of the cam timing.

This is what I'm seeing:



This is what I'd expect to see:



What gives? Am I missing something? I verified all my NWS settings, and the creeping of bank two leads me to believe there's a mechanical problem. Any other parameters I should be logging?

Please don't yell at me about the ignition timing CF's, it's not finalized yet. Fueling is solid as a rock@ 11.5-11.9 throughout the entire rpm range, and FATS are down a bit (4.54 seconds, still slooowww for a full stage3). I'm really leaning towards hardware, but open to suggestions.

Thanks, as always.

what kind of hubs do those cars have? free floating VVT hubs? or are they locked when you do the timing belt?

i would think there would be codes for that?

in my situation one of the hubs was having hard time advancing and immediately threw a code?

Will log it first thing tomorrow morning. Any other variables I should go ahead and log that aren't considered standard? I've got the markp's template with wnwi/2_w loaded.

New logs with the nws variables added.

These logs show a CLEAR cam changeover, as hoped, but bank 2 is still deflecting.

When looking towards a mechanical issue, you had no mention of the oil pressure being verified. I had a cam chain tensioner with partially blocked oil port - but that caused a noise complaint.
