SCT X4 no 91 octane fuel option?

[DarkRattle]

When I go to fuel the only listing is "93, Race Gas". Why is there no 91?

In the menu it says choose between two vehicles, "Mustang Cobra" or "5.4l Cobra R"

So obviously I'm choosing Mustang Cobra, everything else in the tuning works.

YES it's updated.

Is that the generic strategy tune that comes with the device or did you get tunes from someone?

just generic through the SCT flasher, the weirdest thing was that the speed limiter was set "Off", don't these usually have a speed limiter, unlocks left was "5", I'm 100% this is new.

When programming it says ENGINE (CYAE7F8), i unmarried, reset, everything still same thing.

FWIW the 93 tune is probably so safe it can be fun on 91. You can always load it and listen for detonation. Pull timing as needed. Or load it, pull 2 or 3 degrees, and go from there.
