The PTUNING 4-BAR MAP (Manifold Absolute Pressure) sensor is a direct plug-in upgrade for FRS/BRZ/86 customer running forced induction on their vehicle. Our 4-BAR (43 PSIg) MAP sensor allows your tuner to safely tune your forced induction vehicle since the factory MAP sensor was not designed to read boost pressure.
With a linear pressure vs voltage scale, your tune remains consistent with elevation changes. Our 4-BAR MAP sensor can precisely read boost pressure from 0-43 PSIg. Our 4-BAR MAP sensor was designed to replace the OEM MAP sensor, with the housing dimensionally the same, for an easy drop-in installation.
