Is there a way to convert the maps from 3 bar to 2.5bar with out messing them up?

I attached a picture of a 3 bar that was converted to a 2.5 bar setup and it shifts.

Or could anyone send a 2.5bar map?

Who is using the internal sensors?

 

The only way I can think to do it is manually entering all the data points and taking an educated guess at the > 2.5 bar areas of the 3 bar map. I've used the internal sensor and have not had any issues with it.

 

That's what I was afraid of :\

I though there might be a different way of doing it.
