Yes, if you can't up your octane (i.e. 102 or E85) then keep it on Map 2.
You can start off with a 25/75 mix of E85/93 and see how your car likes it on Map 5. Make sure you have flex fuel wires from BMS if you're an N55.
Once logging and tuning is done, if you like it, and want to push more, you can mix 50/50 and go to Map 7, rinse and repeat.
