    Default

    The GM.EOPS PID is now back in the config file, however the LS1 controller returns the value as a voltage between 0 and 5 volts. The default conversion factor and offset for LS1 controllers is:

    kPa = V*1103.125-110.3125
    or
    psi = V*160-16

    Correction, the factors should be:
    1103.125/5=220.625 for kPa and
    160/5=32 for psi.
    The offsets remain the same.

    I recommend creating a calculated PID to display the oil pressure in kPa or psi. I have not yet worked out what the conversion factor is for other controllers (i.e. Duramax Diesel).

    For LS2 applications, use PID GM.ENGOILP which is returned in kPa. GM.ENGOILP is not available in LS1 platforms, which is why you need to create a calculated PID based on GM.EOPS.

    Warning: The factor and offset shown above are calibrated values and on some controllers may be different than the constants I described here.
