    2.5 SD not seeing above 53kPa map.

    updated to 2.5 SD (e40).

    put the 2 bar MAP in (the cobalt one that ends in 698 IIRC).

    wont see anything past 53ish.

    I compared the map setting in diag to another guys sd tune and the map settings look correct. Linear,Offset, and Linear B are all set the same.

    I followed the application instructions for applying the 2.5 option.

    Don't know what to do now.

    custom pid was killing it. deleted scanner.cfg, all good now. except for the fact the it wont go into boost as the map hits 105, it falters and wont go into boost

    I am trying to get into boost at part throttle, could this be an issue?

    I used a boosted ve from another persons tune, put in my 105 then then highlighted to about 200 and blended about 30 times.

    Figured that would be good enough to get me going.

    Fixed

    DTC were not set, was causing it to go to safety when entering boost.

    now boosts, just rich as hell, but NOW I can actually tune it

    Does that map sensor have 3 or 5 pins? Are you using 256kpa for linear and 10.33 for offset? TIA

    He said he was using the 2bar version, so he's probally using the defaults of 200/10.
