If a figure is a minus figure, type minus then the figure otherwise leave dashes out of your figures.

Some actual screenshots would probably help.
My OBD reader records in kPa for the Map sensor, I'll take out the other reading. Sorry my dash marks are just separators, habit of mine.

It does seem the pressure is increasing when at higher revs when it should be decreasing, which would mean I've got a restriction somewhere or a duff sensor?
