So I've been driving this bone stock truck quite a bit lately and decided to revisit the tune to see how things are going. I'm getting KR around 0.64-0.72g airmass in the higher rpm, and in the log I'm seeing towards 20 degrees advance before the KR kicks in. However, in the tune it is only 17-18 commanded. I do not see any adders such as ECT or IAT in this area, and they actually remove timing. Any ideas where this is coming from? Log and tune posted. For this run, I disabled burst retard as well as knock learn, but no change in the logs other than no more burst knock (and still no KR where the burst knock was, in lower rpm areas). I also have a 2nd gear WOT in the log from a stop, at 2:49.111, of which there was no KR all the way up to 2900 rpm where I got off the throttle and let it upshift. Timing in the cal actually starts decreasing from there as you go up in rpm or airmass, yet the log shows it going higher.
The fuel was dialed in with a wideband a couple of years ago and I haven't messed with it since. The wideband is semi-permanently mounted in my other truck at the moment. But as I was saying, I was just revisiting the tune since I am driving it much more lately, and cannot figure out where this additional advance is coming from. I filled up the past 2x with 93 octane, guessing the tank has about 92 in it now. It does not seem to affect the KR at the higher rpm/load, maybe erased some small amounts lower down.
