It takes about 30% more E85 to get the job done. One of the first components needed to work in a flex fuel vehicle is the flex fuel sensor. If you were to make a non flex fuel vehicle into flex fuel capable, you would need that flex fuel sensor, the appropriate tune, larger injectors, sometimes a larger fuel pump and larger injectors.I have limited knowledge when it comes to different fueling options other than what I read being recommended for different tunes. That being said, what are the repercussions (if any) in running E-85 in a 93 octane tune?
I tried using google to figure it out myself and am getting confused. Some have said you need injectors, others that you can rotate back and forth between E-85 and 93 and be fine.
