    2bar os system not working properly

    Im having an issue setting a 2 bar sd tune flash. When I flash the car
    after saving the file on 2 bar sdrtt my map sensor goes haywire. If I
    reflash with rtt 1 bar enhanced flash and enter values for 2 bar sensor, map kpa is fine
    and I can adjust the ve map in real time. when I switch to 2 bar map and check values for
    map sensor which are correct I get a bad value on scanner for map sensor. The car runs
    but not proper and maps sensor reacts like the data posted
    Ive attached a map and data. Ive tried the other 2bar
    and 3 bar sd modes and they do same thing. also on the sd enhanced mode
    wich I used to get a base in I change the values for the map sensor and the
    kpa reads correctly. I test this with a pressure tool and it reads
    correctly on the scanner. If you look at the data you can see map sensor is not working properly.
    Im not sure how else to explain it.

    Can you attach your 2bar os tune file? The SD tune wont work with a 2bar map sensor?
