HOWEVER, if flex fuel is disabled, the Low Ethanol tables/scalar are the tables being referenced even when flex is disabled. I realize this is a bit confusing, which is why I'm migrating back to the OEM tables being used. For example, if you want to edit the cranking IPW, instead of editing Crank IPW 1-6 in Fuel -> General -> Startup, you would instead edit the Crank IPW 1-6 tables in Fuel -> Flex Fuel -> Low Ethanol Content (Leaving Flex Mode still as "Disabled"). The logic remains the same, it's just the table gets moved to a different location in the software. Editing the original OEM tables with custom features applied will make no changes
