hi, would it be possible to add feature of map estimation table, in most new cars there are 2 map sensors, manifold pressure and boost pressure, manifold pressure usually is something like 200kpa or 250kpa sensor, while boost pressure sensor is 350 kpa, would it be possible that when map sensor goes lets say over 195 kpa or some other defined value it would take values from the external table which is based on throttle position engine rpm and boost pressure?

U can already do this.  
Setup a variable with ur condition. Then define the map sensor table in the project tree. And for map sensor table u setup a 4d table with ur condition, real map and alternative map as an axis.

ok, cool to hear, will try that, sounds doable.
