I'm glad to know Triumph is establishing shops in South America, just in case I take my bike there some day.
Electronic fuel injection should be an advantage on changes of altitude because the system is changing its parameters to accommodate for changes in atmospheric pressure (altitude, in your case), air temperature, gasoline, things that influence air density and the mixture of air and fuel. Carburated bikes, you needed to change the needles when changing altitude.
The 15 minutes idle is to reset the throttle position sensor.
I'm curious to know how things will progress on your bike. When in Brazil, you were fueling it with 15% ethanol in the gasoline. But I know it varies to up to 20% in some gas stations. I don't know what kind of fuel they have in Bolivia, but certainly your friend Sylvia would know if they add ethanol to gasoline over there as well.
