Unfortunately i accidentally deleted the 3,4,5 independent 93 pulls so just have the 3/4/5/6 shift pulls.
the pics in this thread.

Order of pics are:

E26
outside temps were 82 deg
3rd, 4th, 5th, then a 3/4/5/6 shift

93 oct
outside temps were 93 deg
3/4/5 shift

Temp rise at end of pulls was

E26
3rd +0, same as start
4th +13.5
5th +25.7
3/4/5/6 shifts +31.1

93 oct
3/4/5 shifts +31.1

So based on the temp data of the shifting logs either E26 or 93 oct the temp rise was the same +31.1 even though the outside air temps were 11 deg higher for the 93 oct pull and the starting IAT was 6deg higher the end result was the same. Also none of the pulls had any registered knock

Looks a lot better than your older VRSF that was really not cutting it for you. I'm not sure there is any way I could do a 3/4/5 shift log, you must really be flying by the end of 5th!

Can you post the links to your logs; I'd like to take a look at the timing, which you've hidden in your charts.
