Measures Boost Levels Up to 58 PSI Plug-and-Play Upgrade Accurately Measures Boost Pressure Compatible with Honda/Acura B Series Engines Description Vehicle Fitment Included Warranty Hondata 4 Bar MAP Sensor for Honda / Acura B-Series Engines If you’re pushing boost on your Honda or Acura B-series engine, the factory MAP sensor becomes a hard limit fast. Stock sensors only read accurately to about 10–11 psi, which is fine for mild setups, but once you turn things up, the ECU is basically guessing. The Hondata 4 Bar MAP Sensor fixes that problem the right way. This sensor lets your ECU accurately read manifold pressure up to 4 bar (roughly 58 psi or 400 kPa). That means your tuner can actually see what the engine is doing under boost and adjust fuel and ignition properly. No more blind spots, no more running out of sensor, and no more risky tuning workarounds. Installation is simple. The Hondata 4 Bar MAP Sensor is a true plug-and-play replacement for the factory B-series MAP sensor. You don’t need to cut wires, modify the harness, or change connectors. Unplug the stock sensor, plug this one in, and you’re ready to calibrate it in your engine management software. Once installed, systems like Hondata S300 can accurately measure higher boost levels and adjust fueling and timing the way they’re supposed to. That translates into safer air/fuel ratios, better drivability, and more consistent power especially on turbo or supercharged B-series builds. Key Features 4 bar MAP sensor reads up to 58 psi / 400 kPa Direct replacement for factory B-series MAP sensor Plug-and-play installation with no wiring modifications Required for higher-boost turbo or supercharged builds Works with Hondata S300 engine management Improves tuning accuracy, drivability, and engine safety Is This Sensor Right for Your Build? If you’re running low boost and staying within the factory MAP sensor’s range, you may not need this upgrade yet. But if your setup is approaching or exceeding stock limits, this sensor quickly becomes mandatory, not optional. Accurate boost data is critical to proper tuning, and this is the cleanest way to get it. For turbocharged or supercharged B16, B18, or B20 engines, the Hondata 4 Bar MAP Sensor is one of those parts you install once and never think about again because it just works and gives your tuner the information they need to keep the engine happy while you turn things up. 1990-2001 Acura Integra 1999-2000 Honda Civic Si 1997-2001 Honda CR-V 1994-1997 Honda Del Sol (1) 4 Bar B Series MAP Sensor There is no warranty stated or implied due to the unusual stress placed on competition product(s) and/or the inability to monitor their modification, installation, and use, unless otherwise stated.
