So does my non-flux model have settings for premium and regular fuel

Yes A map and B map. here is what uni-chip has to say about it;

Each basic kit contains a switch loom with a Map A/B switch. The first position you should try for this switch is “0” which is Map A. Map A is a conservative timing map that all vehicles should tolerate with 87-octane fuel. Map B (the “I” position) is a more aggressive timing map that most vehicles should tolerate with 92-octane or higher fuel.

After you establish a baseline feel for the vehicle running on Map A, ensure you’re using premium grade fuel, select Map B and evaluate the difference. When you select Map B, you may feel a performance increase, a performance decrease, or no change at all depending upon your specific vehicle. If you feel an increase or no change, your engine is tolerating the additonal timing well and you can leave the switch there as long as you are running premium fuel.

If you feel a loss of performance after selecting Map B, your vehicle is not accepting the additional timing and is reducing OEM timing to compensate. Your options are to use a higher octane fuel grade or simply run Map A. If you are using a quality premium fuel and still feeling a power loss in Map B, running Map A is providing all of the potential gain and you should leave the switch there.
