Just passing on what I've found in the various sources. Logically you are correct, but one source says simply that MBT timing is the same for E85 and gasoline, and another report says at low loads the E85 and gasoline like the same MBT timing but at high loads MBT timing for the E85 is slightly more advance.
Heeey ... I think that was me you were quoting.

I only meant that it would allow more advance in terms of knock because of the higher octane. I think I posted that in response to what someone said about tuning it under load ... but I might be mistaken.

This is a very good thread. I love threads with pages of technical information.
