Yeah, shoulda specified I wasn't inquiring in regards to my '88 Accord. That'd be the proverbial golden ring in the swine snout.
Thanks for the link, MetroMPG. Good info.
My OP was triggered by a discussion I had with a coworker regarding FE/octane/knock sensors. Theoretically premium should improve FE as the ECM advances the timing. I just wondered what the ecomodding community experiences in the real world...
Learned something new today; Some (most?many?) ECM's will advance the timing several times until knock is experienced, thereby determining what octane is in the tank, and adjust its spark table accordingly.
