Hi.

Need a way to set up a 4d fuel trim table with one axis being baro pressure. Can`t for the life of me find any way to add more tables to the fuel calculation on a m150 with GPA build.
( This engine will go up and down in hight really fast, and need to be able to compensate for that.)

Hi Sleeper,

This is done using the Ambient Pressure axis in the Engine Efficiency table.

We have run cars at Pikes Peak hill climb on M1's and they haven't needed to use the barometric compensation during the runs, the same as some planes that I have seen the tuning from.
