    Adding boost to pid

    I have searched this to death and still can?t get it to work. Under math parameters but after that I really don?t know what to do. Have about 9 options for map and the function on the tutorial won?t allow the map to stay as the sensor. Have no idea what I?m doing wrong or right. Any help?

    Use this and it will log negative and positive.

    ([11.98]-[51.98])*(([11.98]<[51.98])+1+(([11.98]<[51.98])*.04))

    Make sure you have the following PID's Logged:

    11 Intake Manifold Absolute Pressure in psi
    51 Barometric pressure in psi

    I watched the video but when I do it on mine it returns a negative boost value. My MAP sensor is reading about 4.3 psi key on engine off so even if i do the "MAP(psi) -14.6" it comes back -3 psi boost.

    The most it hit was -12 psi on one of the logs and that was at about 1/4 throttle merging onto the freeway.

    It's a 2018 SRT Durango with a Whipple STG2 kit. Came with a replacement MAP sensor so I would really like to have the boost gauge to make sure i don't hurt anyt
