PLEASE READ: OTS Map FlexFuel users must now select the flash option for "Motiv FlexFuel kit installed" in order to use the custom feature. If you are currently running FlexFuel and do not select the checkbox on your next flash, the FF logic will be removed. All previous requirements remain: you must own the pump gas map pack, ethanol map pack, and FF license (or super license), and flash a V8 or higher pump gas (not ethanol) map, but now also with the flash option checked. This flash option checkbox will only be visible if you own the correct licenses and are flashing the correct OTS map. There are no changes for custom FF tunes (flash option hidden as it is not needed).
