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.

Have a LS1 Vx commodore... have been loging eops and can see the voltage in BBLlog... Can some one point me in the right direction to a thread that will tell me where and how to enter the above information... would love to read it in PSi and have a alarm in BBL for low oil when running the 1/4
