    The MPX4250 is excellent value if you are wanting to run a boosted engine at around the 20psi mark, or if, like me, broke the original map sensor that was supplied in the kit haha

Can this be used as an external MAP sensor?

  • We do not recommend this. To protect the sensor from vibration, you both solder its pins to a circuit board and bolt the pins to the same board. The pins are not intended to connect directly to a wiring harness.

What MegaSquirt units can I use this sensor with?

  • This one works with V2.2, V3.0, and V3.57 main boards, as well as the DIYPNP.  It does not fit the MSPNP Gen 2 or MSPNP Pro units, and we do not recommend it for systems with an external MAP sensor, as noted above.
