What do you guys see timing wise?
#17
Here's me getting on the freeway up a slight grade from a stoplight and then coming to a stop a few times--typical Bay Area freeway traffic. When accelerating onto the freeway, I was up at 30% throttle right around 7:42
Looks like timing is all over the place while cruising freeway speeds depending on throttle and load.

I've been wondering that ALSO.
When it says it's injecting at "4", does that mean that's where the pilot injection starts, or the main injection ? How can you tell the time spread between the 2?
How is the duration between the 2 calculated? When the timing gets bumped, does that pilot injection get pushed way to far?

I never plotted mine as you did, but just from paying attention to the timing while cruising, I suspect mine would exhibit very similar traits tuned with the latest tunes.
To me, this means this portion of the programming has not been cracked yet.
If it was, I'd expect to see a much more linear correlation, and I doubt we'd be seeing these weird fluctuations that are present. I'd also expect that at steady output on the highway, we'd see a nice steady line of advanced timing. Injection after TDC is probably a mileage killer in itself.
