Thanks RacerX. Good info in that link.
Sort of confirmed what I had thought, that the system can adapt to lower octane fuels when needed. Around here it seems 87 or 91 are the two options. I recently was on the interstate and running very low and stopped at a clean newer looking station out near the highway. They only had 87 with 10% ethanol or 87 pure gas.
It can and does happen at times where higher-octane fuel might not be available. Turns out a tuned truck still runs perfectly fine with 87, which I really thought it would, but nice to see more details on how it actually works, and what it was designed to do.
Honesty I could not tell an any difference in the seat of the pants feel with that full tank of 87 vs the prior full tanks of 91 that I had been running after tunning it.
I imagine there is some differences, or there should be some performance difference.
