First you need to determine what your original 1 bar sensor is reading at your location above sea level. With your original tune installed and the original 1 bar sensor in place, record the kPa at key on engine off (KOEO).

Now install the 3 bar OS along with the new sensor. Change the linear value in the tune to 245 and turn the KOEO and check the new displayed value. If you change the linear value up/down the KOEO value will also change accordingly. Once your value matches that of the original sensor, it is set properly. (Ex. Mine in EFILive is 248.0078)
