Just to verify:

        //newValue = newMax + (newMax - newMin) * (oldValue- oldMax) / (oldMax - oldMin)
        input = 1 + (1 - 0) * (input- 1) / (1 - -1);
        return input;
    }

You can verify it by plugging in your input extremes (-1 to +1). I haven't had my coffee yet, but it doesn't seem like -1 converts to 0. Why not try the one I posted? KISS
