Small snip of a very short 4th gear pull this morning in the zip file. File size is very limited on the forum.
Timing is extremely conservative (imo) and still getting some knock down low, which is looking more and more like blower or header noise to me than real knock. BUT - I'm a turbo guy, and this platform is still foreign to me. Running 93 and have added boostane to see if it eliminates it - it does not. Screen shot of a different pull - can still see the light KR in the same region. I assume the knock learning will eventualy nip this, but dont know for certain. Any advice to diagnose would be appreciated.
Going to hit the dyno tomorrow to get some reliable 4th pulls. Will be getting a wealth of data from those runs, naturally.
That said, depending on the situation it's somewhere around 8-12 degrees in the suggested rpm range.
