Genuine gm 2 bar map sensor.
Gm 2 bar map sensor offset.
Divide the pressure range by the voltage range to calculate the scalar.
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.
I found the specifications a few voltage mbar specs at this online store s product page.
Subtract the minimum and maximum voltages to find the range then do the same for the pressures.
They can measure up to 2x the apmospheric pressure.
Installing a supercharger or turbo on your lsx powered vehicle.
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.
I added 4 in the map sensor offset and it only changed to 3.

According to the specs the gm 3 bar reads the following pressure is absolute 501 761 volts 631 average 40 kpa 4 784 5 044 volts 4 914 average 304 kpa.
Key on the gm map sensor read 102 the holley map sensor reads 100.
1 bar map sensors are used on na naturally asperated vehicles.
Can i use the offset to bump up the kpa to 102 or is the 002 difference not worth worrying about.
These sensors accurately produce voltage or frequency as intake manifold pressure changes and the computer uses this information to measure.
2 bar map sensors are used on forced induction vehicles turbo supercharged.
I ve been running a 3 bar gm 2525 and switched to a holley 2 bar.
I m running a holley hp with a 3 5 bar map sensor.
Here is how to calculate the scalar and offset for a map sensor.
2 bar map sensors are used on forced induction vehicles turbo supercharged.
The sensor reads 4 with the engine off.
1 bar map sensors are used on na naturally asperated vehicles.
Convert the pressures to mbar.
Chevrolet performance map sensors are high quality direct fit replacements for worn or malfunctioning map manifold absolute pressure sensors.
