In the remapping of output options there is a selection called MAPSELO, is this the MAP input 5V eg MAP+ or MAP_S or something else. Just playing around with the box and trying things out so not critical at all.
I upgraded firmware from 4.3 to 4.4 successfully so its all working well so far.
Very useful feature, so you have 4 switchable Maps, I know some racers who could use this in practise to see which suits that circuit best. I plan to use the normal 2 selectable Maps for high octane and low octane fuels.
