The Perrin Performance 4 Bar MAP sensor allows you to safely run above the factory MAP sensor limit of 24PSI. Now you can safely run boost levels above 24PSI and accurately produce maps based for higher boost levels (Up to 43psi). The Perrin 4 BAR MAP sensor is 100% plug and play! There is no need for throttle body adapters, or harness adapters. With a Philips screw driver, you can have this installed in 2 minutes! Included are instructions on how to integrate this into your AccessPORT Tuner Software, Cosworth ECU, AEM ECU, ECUFlash as well as many other systems.
The Perrin 4 Bar MAP sensor uses state of the art bipolar op amp circuitry with thin film resistor networks built into each micro chip. Pressure changes are calculated on a true linear 0-5 volt scale via a specially designed silicon pressure sensor that also compensates for temperature changes. The unique ability to compensate for temperature changes allows the PERRIN Performance 4 Bar MAP sensor to remain a minimum of 99% accurate from 32 degrees F to 180 degrees F through out its range of scale. With the true linear pressure vs. voltage scale there is never a need to re-tune at different altitudes as with other sensors.
