Convert the pressures to mbar.

Gm 2 bar map sensor offset.

They can measure up to 2x the apmospheric pressure. Find the minimum and maximum voltage and absolute pressures. 2 bar map sensors are used on forced induction vehicles turbo supercharged. Also known as boost solenoid pressure sensor m a p sensor barometric sensor barometric pressure sensor manifold absolute pressure sensor etc.

I ve been running a 3 bar gm 2525 and switched to a holley 2 bar. 2 bar map sensors are used on forced induction vehicles turbo supercharged. Subtract the minimum and maximum voltages to find the range then do the same for the pressures. 1 bar map sensors are used on na naturally asperated vehicles.

Genuine gm 2 bar map sensor. It took 2 0 to get the sensor to zero out. If your tuner recommends it you may need to use a two bar map sensor for your application. Here is how to calculate the scalar and offset for a map sensor.

Installing a supercharger or turbo on your lsx powered vehicle. Key on the gm map sensor read 102 the holley map sensor reads 100. They can measure up to 2x the apmospheric pressure 29 4psi so that means it can measure up to 14 7psi boost the atmosphere is 14 7psi 14 7psi from the turbo supercharger. 1 bar map sensors are used on na naturally asperated vehicles.

The sensor reads 4 with the engine off. Can i use the offset to bump up the kpa to 102 or is the 002 difference not worth worrying about. This is for the gm delphi 3 bar map sensor with part number gm part 12223861. I found the specifications a few voltage mbar specs at this online store s product page.

These sensors accurately produce voltage or frequency as intake manifold pressure changes and the computer uses this information to measure. I m running a holley hp with a 3 5 bar map sensor. I added 4 in the map sensor offset and it only changed to 3. Divide the pressure range by the voltage range to calculate the scalar.
