Flex Fuel kit, tunes - switching between fuels

Hey guys,

I'm new to the 86/BRZ scene, recently sold my 96' NA Supra for my 2013 Manual 86.

I'm currently running a stock exhaust and headers w stock ecu map.
So far ive settled on these mods for the next few months:
- XForce catless headers
- Xforce catback
- K&N hi flow filter
- stage 2+ (E85) via ecuflash tactrix

My question is: is it worth buying a Flex Fuel kit for my 86? Is there any other benefit besides knowing ethanol percentages. If i do, will my ecu be able to recognise when I'm running 98 octane or E85 (can i switch fuel without having to re-tune)?

Worst case if im low on fuel and theres no other options for E85 i just re-tune my ecu to 98 octane when im at the servo (just carry my laptop around along w tactrix).

Need some advice just not sure what to run atm, i have E85 pumps rly close to me so daily driving w E85 is not a problem at all.

Thanks
