I never have used E85, & I have only pumped 100 octane, but for whatever reason, when I put 100 octane in, my CEL comes on.
I did a couple of tests and didn't run the racing fuel for awhile, and only pumped 91, and eventually the light would turn off on its own.
Then I would pump 100 again, and boom, back on.
Not sure why the 100 octane makes my light come on, but it definitely does.
