Among the most important inputs for your Engine Control Unit is pressure in the intake manifold. Using a high-quality and accurate MAP sensor such as the Sniper EFI MAP Sensor helps the engine to respond to any changes to the manifold pressure and the ECU to respond in voltage signals that go from 1 to 5 volts. Sniper EFI MAP Sensors are available in 1, 2, and 3-bar models for varied applications.

Sniper EFI MAP Sensors make use of the stock attaching points to simplify installation and make it hassle-free. The sensor measures the manifold vacuum as well as the output voltage going to the ECU as in the form of a function of the engine load. This provides the required parameters for fuel enrichment. Holley EFI 2 Bar sensors are also available that can be used in forced-induction applications with a boost of 14.7 PSI. This specific MAP sensor can be used on all vehicles- emissions controlled and uncontrolled as well as race-only vehicles.

The Sniper EFI 2.5 bar MAP sensor is made specifically for Emission Controlled Vehicles. It is suited for applications that require up to 25 lbs boost. With Holley EFI systems, Part number 558-416 is also needed.
