The pinging IS FROM THE E10 I think (not my area of expertise). when I get E0 it stops pinging. (at least it did back then) I did not pay attention to if it pinged when I was on washed gas so I assume it did. I only ran washed gas for a few tanks to confirm if it was worth the drive and expensive to go get some E0 for more testing.

right now I am not washing gas (again only did that for 30 or so gallons of gas last spring) I am just using pumped E10 from any normal gas station.

I can not advance the timing any more without damage to the engine.
