I just had a quick (well, took me 10 mins) look through MK’s build thread and found this pic:



So it looks like it was mapped with the 5 bar sensor, but it does indeed look like a 3bar sensor linearisation on the screen shot supplied above, are you sure you are looking in the correct place in the software?
