Fuel injected models are equipped with an atmospheric pressure sensor which acts as the high altitude compensator. The atmospheric pressure sensor senses pressure and converts it to a voltage which is sent to the ECU. The ECU computes altitude and corrects air/fuel ratio and ignition timing. For complete information on this system, see ELECTRONIC CONTROL INJECTION (ECI) SYSTEM article.
