I did a compare to a stock file and the PIDs are much closer to stock than I would have thought. If it were in my shop I have the luxury of having stacks of PCMs and unlimited credits so I would...

Oh I beg to differ sir. It is perfectly obvious and I'm surprised it's as smooth as it is in this log. The throttle blade is WAY too active. Without even looking at the tune file the throttle PIDs...

Does it need MORE fuel or LESS? Have you tried WOT clear flood mode? Are we just assuming it needs MORE fuel? Have you tried just cracking the throttle?

Do you have data logs of various starts...

Congrats on the find. Right at the buzzer. 5 pm quittin time LOL

If there was enough valve train damage to cause a noticeable miss I'd think there would be some noise involved.

If there was enough valve train damage to cause a noticeable miss, it should show...

If the VE in that revision has been dialed in up top with your wideband, you're losing fuel pressure. The VE should not be anywhere near that high.

The high octane spark table still has bad dips...

Put it back in closed loop and use the trims to dial it in. Forget about your wideband. Straighten out the spark tables. Get rid of the cliff in the VE table at 6400 RPM.

Short answer is no. Break out the calculator. Start crunching numbers. Make it fit.

Biggest problem is it's overly rich and it never goes into closed loop. You have every single O2 code set to no error reported.

There's weird dips in the spark tables. Dips you'll transition...

If you had the trans built locally I'd take it by the builder's shop and let them drive it.

What converter is in it?

That or disconnected. Need a data log, or check codes, something more than year old logs showing it running.

Logs from a year ago when it was running mean nothing at this point. Have you scanned it? What are the codes? Have you called Brent about it?

Scrolling through the log in this post everything looks normal. I just scrolled through quickly looking at the O2s and trims so could have missed something else.

Rear main seals rarely leak. It's...

That's the kind of information we need to be able to help. I don't care how old you are you need to be able to put together an intelligent post so people know what's going on.

Do you have a data...

How about constructing an actual paragraph of what's going on, the work you did, etc. Enough of this one-line BS. Communicate like you have some level of education.

FFS there needs to be some sort of competency exam to pass before you're allowed to buy this tuning package.

The fuel smell is from a cam with overlap. If you take the cats off a bone stock LS car it'll stink pretty good. Put a cam in with some overlap and it really stinks up the joint. You understand what...

If you're hearing audible knock under light load I would start by doing an induction service on the vehicle to get it de-carboned. Might want to try high octane fuel if you're not already running it....

I just looked through a half dozen GEN3 OE files including a couple of the same OS and that code is set to no error reported in all of them.

This is right off the repository.

Where's the tune file????

Can you be more specific? How far are they from the cylinder head? Can you put them closer to the manifolds?

Posts like this are just ridiculous. I mean c'mon man. No explanation of what you're working on, modifications, etc.

How about posting an actual data log instead of a picture of one???

I'm not understanding why we don't start with the obvious first? VVE is still not straightened out and it's in speed density. No wonder it has a tip in stumble.

I went back and read your initial...
