NAMR feature description

Fill and forget! CAN-based ethanol flex fuel sensors measure the ethanol content of your fuel and adapt your tune to a variety of parameters such as fuel target and ignition timing to make blending fuels or filling at an unmeasured E85 pump extremely simple. A staple of the Subaru community, flex fuel makes your FA24DIT run even better by unlocking significantly more ignition timing due to an increased knock resistance.
