Acceleration Curve

[Cuog]

I'm not entirely sure what the error is in your code i will take a look at it again but if u want here is the method i used for doind the same thing u are doing:

try adding brackets for order of operations:
tempRight = (((tempRight - 127) * (tempRight - 127))/127) + 127;
