I'm down to ~5 gallons of my 93.25 Octane blend, and it's been 5 days since I took the logs above. I'm going to capture a few more logs today with the same blend and see if DME adaptation has improved anything, and then add the remaining 2 gallons of 100 octane race fuel that I have and capture some more.
The theory is that if the timing events improve with a higher octane blend, my issues are octane related, and unfortunately that means that the BM3 91 Octane Stage 2 OTS tune really isn't a 91 Octane tune, but a tune requiring greater than 93 octane fuel.
If the logs look good with the higher octane blend, I'll step things up to the 93 Octane Stage 2 OTS tune and see if I can get consistently good timing with my new higher octane blend there as well.
... Watch this space!
