exactly how I put it, I see alot of guys claim true flex fuel tunes but appears using the math logic or on the hellcat some wideband feedback. however alot of room is still left on the table. for power and for error.
Satera tuning as far as I have seen adapts the flex fuel sensor into the mix and has it scaling the fuel and the timing which would be a true flex fuel system. AM I missing something else? I see advanced fuel dynamics kit but that only adjust the fuel side, still would have to pull over swap tunes based on content to gain any power with raised timing.
