So tuning with a haltech elite 2000 with a flex fuel sensor and starting tune with e85. My question is should I load the main map settings(fuel, ignition, boost) with my E85 parameters. And then add my gas settings into the alternate maps(fuel, ignition, boost). And then flip the values on all correction tables. So the less the ethanol content the more it uses the alternate maps?

not super familiar with the Haltech flex fuel platform but every flex fuel i have ever done works on 0 ethanol first as the base tune and e85 compensation is added over this not the other way around
