Does ethanol affect performance tunes?

Does ethanol affect performance tunes?
I have been contemplating purchasing a CAI with XCal2 loaded with performance programs for 87, 89 and 93 octane.
My question is, at least here back east, the gas pumps have stickers that state the fuel can contain “up to” 10% ethanol. Assuming the fuel does indeed contain 10% ethanol do the turners account for the possibilities that fuel may have up to 10% ethanol or is it just back east that has ethanol added to the fuel?
I don’t know much about how ethanol may affect the A/F ratios and wouldn’t want to chance having a performance tune and then the ethanol causing a lean condition or contribute to “knock”.
Anyone know, or how about any of the tuners out there?
