OMNI POWER MAP-U-4BR UNIVERSAL 4 Bar Map Sensor (Absolute Pressure Sensor)

With the true linear pressure vs. voltage scale there is never a need to re-tune at different altitudes as with other sensors. Competitor's sensors on the market don't have true linear scaling which can cause your engine to go out of tune with elevation changes, often resulting in idle problems, poor drivability, and catastrophic engine damage. Omnipower 4 bar MAP sensors can precisely calculate boost pressure from 1-43+ psi while still allowing smooth stock OEM drive ability at any boost level. Conveniently packaged in an OEM dimensional housing for easy install and an OEM look. Key Features: Upgrades GM 3 Bar to allow up to 43.5 psi of boost Pressure tested to over 130 psi without leaking -40 to 260 degrees Fahrenheit optimal temperature operating range Able to respond from 10% of the pressure scale to 90% of the pressure scale in .001 seconds (the fastest response time of any MAP sensor on the market) which translates into improved boost response. Automatic temperature compensation. True linear scaling for perfect drivability at all boost and vacuum levels. Compatible with all aftermarket engine management systems. Minimum of 99% accurate over full scale range under all conditions including temperature, altitude, and humidity changes. Allows smoother engine operation, higher boost levels, and better drivability than competitor's turbo MAP sensors. Each sensor is hand assembled, pressure, and function checked in the USA for unparalleled quality control prior to shipping. Pin Out is: A=Positive 5 Volt Source B= Negative/Ground C= Signal to ECU Please Note: As with any upgraded MAP sensor, you will need an engine management system in order to re-calibrate the ecu.
