Why You Need This

Standard MAP sensors fail catastrophically in high-boost applications — we've seen countless 2JZ, RB26, and LS turbo builds running lean or pulling timing because cheap sensors can't handle the pressure swings. This 4 Bar unit is engineered for motorsport punishment, reading accurately up to 58 PSI where lesser sensors read incorrectly or fail entirely. The Deatsch connector system ensures rock-solid connections that won't vibrate loose during competition.

Critical for any build exceeding 30 PSI boost, including big turbo SR20 builds, compound turbo setups, or methanol-fuelled drag cars. Your Haltech ECU relies on MAP data for fuel calculations, ignition timing, and boost control — inaccurate readings mean inconsistent AFRs and potential engine damage. This sensor's linear output and motorsport-grade construction eliminate the guesswork, giving your tuner the reliable data needed for consistent, safe power delivery across the entire boost range.

ECU & System Compatibility

Compatible with the full Haltech Elite and Nexus range including Elite 550/750/1000/1500/2000/2500 and Nexus R3/R5 ECUs. Direct plug-and-play with Haltech's calibrated MAP sensor inputs — no custom scaling required. The proven Deatsch connector matches Haltech's recommended wiring standards for professional installations.

Complete Your Build

Most customers building high-boost applications also add the HT-020400 Boost Control Solenoid for precise electronic boost control and the HT-010200 Air Temperature Sensor for accurate charge air monitoring. These three sensors form the foundation of any serious forced induction setup.
