They are at Engine Diags, AIrflow, MAP sensor, right where you set slope and offset. :)

Normal local baro pressure should show at key on. HPT gives you the option of disabling the test or setting DTC's to no MIL or no error reported. Never seen any ill effects.

AFAIK there is nothing you can do about except set to NO MIL. You can recalibrate the range and offset for the sensor reading as you have done, but that doesnt recalibrate the diagnostic routine...
