Regarding your air-cooled comment: Typically as both the motor and the ambient air temp increase a fuel injected motor is operated with a leaner mixture. Air-cooled motors even more so.

A hot motor, with warm intake air, will continue to run on very lean mixtures. The motor doesn't make the same power as it does with a richer mixture, but it runs cooler and emissions are lower.

The IICE Air puts a 'lower intake air temperature offset' into that lean mixture trend. The ECU responds to that 'temperature offset' with a richer mixture, and the motor makes better power at all ambient temps.

Gotcha! Thanks! So then my assumption of all the other sensors remaining in play is correct (ambient/ intake pressure, etc). No worries about riding from Death Valley to Mt. Evans and the pressure changes
Not that it is in my near future
