I was looking for the air pressure trim in the map but I could not find it so I guess that it is not possible to see it and it can not be changed. Does any one know how the altitude compensator works. I am in the process of transfering some maps from my Ultimap ECU and need to know if it is any difference so I can compensate for it in the map it self.

So at at 1024 it is no correction at all and from that it is allways substracting fuel (as airpressure gets lower).

Correct?
