Sensor - Alpha Performance 4.0 Bar MAP Sensor (R35 GT-R)

Inaccurate boost control can be found when higher boost levels are run on a GTR, but with this 4.0 Bar MAP Sensor Upgrade, that is no longer an issue. The factory MAP sensor only reads to 24 psi reliably, which leaves very little room to have a working boost cut in case of an over-boost situation. The factory boost control is also pressure based, so after 24 psi there is no longer any ‘control’. The boost will run whatever it wants to in relation to air temperature and density for that day. There is also no way to log or tell how much boost a car is running when it is over this limit. But with the use of this Alpha MAP Sensor Upgrade, boost can be controlled accurately up to 44 psi! This will not only give you regained control over boost, but will also allow for better data collection for your tuner, resulting in a more accurate and safer tune on the dyno!

Every Alpha MAP Sensor Upgrade includes the necessary calibration parameters and tuning tips, which will allow for plug and play installation without a lot of guess work. No cutting of wires is needed when installing this MAP sensor upgrade because it uses the same stock connector to plug right into the factory harness.

The Alpha MAP Sensors will work with the stock ECU or any aftermarket engine management system available.
