What we need is another sensor that reads the ambient air pressure so the kit can adjust for elevation/weather changes without changing the map or requiring closed loop to be used.

On a lot of bikes and cars, the O2 sensors are just for pollution control. Reportedly, the Ninja 300 only has one on the CA models and the 49 state models have none. They use a barometric sensor instead.
But even still, it wouldn't work with our bikes. Cars and factory bikes have some kind of mechanism to increase the air flow in high altitude areas because lowering the fuel flow is not always an option due to the mechanical limits of the injectors and the fact that you don't want it to idle too slow.
I'm wondering if Setasi has even done that trip with a carbed Ninja 250 and what the results were.
