Informative video, thanks, I'm surprised at how large the scale of crank timing ended up being with the temperature change, way larger than I would have thought.

I'm keen to see what the crank angle / timing ends up being when changing the EOIT 4 hex bytes at a time.
Thanks heaps for this.

One thing that does make me wonder though, is the reference used by EFILive regarding the math equated output figures used, eg: the scale of 2.55078 at low temp to 5.55078 at full temp, those figures are displayed as being a measurement of mS, which I understand to be milliseconds.
If that were the case, the crank angle at which the EOIT occurred would differ as the rpm altered.
On the setup you're using in the above video, does changing the rpm alter the crank angle of the EOIT.

Also when looking through the later LS2 tunes, I notice that the EOIT is oddly familiar to the earlier LS1 with regards to the plotted figures when displayed in the graph screen.

Also as a side note, changing the final figures of 5.55078 decimal / 058D hex to 0595 hex, has my L/100 figure drop by .3 /100, even when occasionally throttling hard off the line at times, and that's city driving, not highway.

Seems to shift it's timing as much with throttle position as does with temp change, I'm surprised I actually felt the improvement I did with the small changes I'd made.
Thanks for the demo, really appreciate it. :thumbup:
