I'm only suss on it not against it.
Kido tune likes the E85 stuff but I went a 98 tune..... Which has been great btw....
The myth about ethanol is mostly that - myths and fiction:

Post 1988 fuel rubber hose composition will not rot away with ethanol. (Link above to patent for the sceptics, as well as an independent experiment report showing immersion impacts of ethanol on fuel)
Ethanol is fine if you set things up right - you will get some condensation on moving parts exposed to fuel, including exhaust which may cause rust. So untreated or uncoated mild steel exhausts may not be best for ethanol.
Other things to be mindful of are oil dilution, ethanol content variation, and over advanced timing which is masked by high knock threshold whilst you may actually be pushing too much cylinder pressure and exhaust gas temps, robbing you of power and longevity.
That is, you might be running very big timing advance, and see no knock at all, when in reality you're way ahead of mbt (mean best timing) which is not good. Alot of tuners don't look for this fact, particularly at peak torque (which is highest dynamic cylinder pressure)
All of these can be fixed though with proper oil choice and regular oil change intervals, correct spark plugs, a wideband afr gauge to monitor afr on the fly, and a proper egt or experienced tuner on the dyno.
