I kept pulling timing and finally got to a point were it would not knock. I'm trying to post a log, but it is having a hard time uploading.
I have a 2018 CTS-V that keeps displaying knock under WOT. The only modifications to the car are a Griptech 2.30" pulley and a Stainless Works cat back exhaust. As you can see in the attached logs,...

Sorry about that...
Friday start up #1. Flared and died. First start attempt of day after sitting in shop overnight.

Friday start #2. Changed min transient value to .015 ms. Flared and died. ...
There is a wideband in the car, but it is so slow to respond that I find it pretty useless on start up. I am going to hook up my dyno widebands today to get some more data. This will include AFR on...
Running SD. MAF is removed.
I am working with a LS1 that has been stroked to 383 inches. Trickflow heads, aggressive camshaft, FAST intake, big throttle body, etc (I can get specifics on these items if needed). The car runs...
Working with a 525hp LS3 crate engine from GM. This has the "ASA" GM camshaft. OS is from a Gen3 1999 Corvette. After lots of learning (and criticism) I have the engine running and idling pretty...
I haven't touched the Adaptive Idle functions yet. The idle has come a long way since my last post. However the Throttle Position % is still around 10% at idle. I assume if I drilled the TB blade...
I plugged in the MAF sensor and it seemed to help the idle surging quite a bit. Perhaps my VE tables need more work?

I'm having trouble getting the idle to settle down on this project. Attached is the latest tune and log file. I've tried more timing, less timing, more air, less air, VE table...
Good info, thank you.
I have a customer that installed a LS3-525hp crate (aka LS376-525) (GM PN 19369338) (link http://www.chevrolet.com/performance/crate-engines/ls376-525) into a C5 Corvette. The plan is to use the...
Ok, thank you.
Is there a way to eliminate the TC, ABS, and 'Service Engine Soon' lights associated with eliminating the Active Handling and Traction Control on a 2001 Corvette?
Does HP Tuners (or anyone else out there) have a re-calibrated MAF table for a Ford Racing cold air intake on a 2006 Mustang GT?
I've seen this too. Car makes good power otherwise. Sometimes the combination of parts just does dome weird stuff inside the intake manifold. I would love to try a different set of headers or a...
Yes, below peak. Peaks about 5K.
This is a manual trans.
No step down adapter. Intake was modified to accept the 90mm TB.
This is the range that has the torque flat spot. So it makes sense that the air mass shows irregularities in this range as well.
It was cleaned before testing started.
I've tried tests with...
I loaded in this tune and retested, but the flat spot in the torque curve prevailed.

It isn't a dip, but the curve goes flat from about 4,000 - 4,200 rpm.
Yes, the screen is still on the MAF. I thought that the curve looked a little choppy when I was adjusting for AFR's as well.
I have spent quite a bit of time trying to get the VE table to...

This is the tune file I plan to load and run in the morning. Any feedback?
