Will the maps still be switchable so that I can switch from low boost to high boost?

Even though WA and OR gasoline filling stations now all use about 10% eth, I'll likely keep my low eth map tuned to 0% eth to allow for situations where I road trip to a state where ethanol is not required in gasoline.
I guess my suggestion comes from someone who doesn't fully do their own tunes so I don't touch the maps so much, but if you can explain how to take the existing maps and interpolate them to e0 and e100 then that's good enough for me

I believe there was only enough memory for a second set of maps when tephra did his mod so this patch won't create new maps except for perhaps the interpolated one. Mrfred, correct me if this isn't your intention.

If you are using the toggle to switch from low to high boost, then for sure it will go away in m1 because the ethanol content signal will be fed into ADC_0F which is the same input used for toggle-switch based map switching. If enough people want low/high boost, I may be able to implement some alternative means, but that wouldn't happen until m2.

I could, but it would save me a lot of time if I did it with my own ROM which I have much more extensively annotated. If tephra doesn't send me something soon, I might do the 96530706.
