Lowdoller Motorsports 5 Bar MAP Sensor – -1 to +4 Bar Part Number: 899005 Accurately monitor manifold pressure across a wide operating range with the Lowdoller Motorsports 5 Bar MAP Sensor, designed for boosted street, drag racing and motorsport applications where reliable pressure data is essential. This sensor measures from approximately -14.5 PSI vacuum to +58 PSI boost, making it well suited to turbocharged and supercharged engines operating at substantial boost pressure while still retaining the ability to measure engine vacuum. The sensor uses a standard 0.5V to 4.5V analogue output from a 5V input, allowing straightforward integration with compatible EFI systems, digital dashes and data loggers. At the low end of the range, -14.5 PSI corresponds to 0.5V, while +58 PSI corresponds to 4.5V. With a heavy-duty stainless-steel body, 1/8" NPT thread and an advertised accuracy of 0.5% of full scale, the Lowdoller 5 Bar MAP sensor is built for demanding motorsport environments where dependable boost data matters. Features & Benefits 5 Bar MAP sensor Measures from -1 Bar to +4 Bar Approximate operating range of -14.5 PSI to +58 PSI Suitable for high-boost turbocharged and supercharged engines Standard 0.5V to 4.5V analogue output 5V sensor input 0.5% full-scale accuracy Heavy-duty stainless-steel body Compact 1/8" NPT threaded connection Compatible with EFI and data-logging systems Suitable for demanding drag racing and motorsport applications Supplied with GT150 connector components Technical Specifications Product Type: MAP / Pressure Sensor Brand: Lowdoller Motorsports Part Number: 899005 Pressure Range: -1 Bar to +4 Bar Approximate PSI Range: -14.5 PSI to +58 PSI Sensor Rating: 5 Bar Signal Output: 0.5V to 4.5V Input Voltage: 5V Low-End Calibration: -14.5 PSI = 0.5V High-End Calibration: +58 PSI = 4.5V Accuracy: 0.5% of Full Scale Pressure Connection: 1/8" NPT Body Material: Stainless Steel Application: Universal Motorsport MAP / Boost Monitoring What’s Included 1 × Lowdoller Motorsports 5 Bar MAP sensor 1 × GT150 Packard connector Connector pins Connector grommets Note: Pre-wired cable is sold separately. Applications High-boost turbocharged engines Supercharged engine combinations Drag racing applications Street and strip performance vehicles Intake manifold pressure monitoring Boost control and logging EFI systems Digital dash systems Race-car data acquisition Engine protection strategies based on manifold pressure Ideal for High-Boost Applications The 5 Bar range makes this sensor a strong choice for performance combinations that exceed the usable range of conventional 2 Bar, 3 Bar or 4 Bar MAP sensors. With the ability to read up to approximately 58 PSI of boost, it provides the range required for serious turbocharged and supercharged applications while maintaining vacuum measurement below atmospheric pressure. This makes it particularly well suited to drag racing, high-output street cars and other combinations where accurate boost data is critical for tuning, boost control and engine protection. EFI & Data-Logger Compatibility Lowdoller states that the sensor is compatible with all EFI and data-logging systems capable of accepting the appropriate analogue input. Typical installations may include: Haltech FuelTech Holley EFI Racepak MoTeC Link ECU ECU Master Other compatible EFI, dash and data-acquisition systems The receiving system must be configured with the correct 5 Bar / -14.5 PSI to +58 PSI calibration to ensure accurate readings. Important Installation Notes The sensor requires a regulated 5V supply, suitable sensor ground and compatible analogue input. It uses a 1/8" NPT pressure connection, allowing it to be installed directly into a manifold, sensor block or remotely mounted pressure line. Always verify the ECU or data logger calibration before relying on manifold pressure readings for boost control, tuning or engine-protection strategies. Why Choose Lowdoller Motorsports Sensors?
