atmospheric pressure is only one part of the puzzle.
Systems using a MAF sensor, measure air mass, density, and temperature at the same time. the o2 sensor provides a closed loop, and the system is truly tuned no matter what. its the only system that accurately adjusts for a wide range of operating environments.
the throttle adjustment on my euro throttle could have servo mounted easily.
the only problem is that once i install that, i'll need another piggy back computer, sensors, and software to control it.
i think an easier route is to make a high altitude fuel map and a spacer for the throttle body stop. the rider just has to remember to remove the fuel map/spacer after he gets below a certain altitude.
