For mitsubishi, you /may/ need to use the ‘boost adjust’ function in the vehicle profile

This should be +/- 14.7, or 0, depending on the vehicle – Most vehicles it should be set to ‘0’, apart form some Mitsubishi, where (of required on that paticular vehicle) it should be set to +/- 14.7

You should get a vaccum at idle (on petrol vehicles. On diesel it should be nearly 0) and obviously +boost when the ‘go’ pedal is pushed firmly down

Hi

It sounds like 0 is the correct value for your vehicle

The reading (via the sensor) is a direct read, as reported by the ECU. The maximum reading for it should be (after taking atmospheric pressure into account) at sea level, about 22 to 23 psi (this is a sensor limitation of the MAP sensor as it reads a maximum of 255 kPa (-atmospherics – 101kPa)

If you have a MAF sensor you can get a reading above this however – go into the OBD2 adapter settings, and change the boost calculation from MAP to MAF, and the app will then use that sensor for the boost calculation (if it is present in the vehicle). Make sure the vehicle profile is setup with the correct information first though.

You can check if the MAF sensor is present by looking in the Adapter Status screen at the bottom (supported sensors) for ‘Mass Airflow’

Tried Maf based, but i think its still reading higher then it should.

I compared it with Evoscan, i am touching 26psi at peak torque, but on the phone screen it reads 29ish~30 looks like it reads 3ish psi more than it should.

off evoscan i am logging mut 2380872E and the formular is (x/4*0.19347)-14.5 does it mean actual boost is only 14.50-X*0.23) of raw value? if it is true, that comes out to 3.34 which sound about right
