From what I understand, you cannot tune it manually. However, the autotune is supposed to continualy tune the saw for varying conditions (different fuels - like switching from E10 to "real" gas, different altitudes or atmospheric pressure, partially clogged air filter, etc.)
It does make me wonder about using these autotune saws for chainsaw milling. Usually people run rich for this application, to protect the saw from overheating in a long cut. Will the autotune handle such a situation?
