3 Bar Motorsport MAP Sensor

Overview

The Haltech 3 Bar Motorsport MAP Sensor delivers precise manifold absolute pressure readings up to 3 bar (43.5 psi) for high-boost turbocharged and supercharged applications. Essential for accurate fuel and ignition mapping on modified engines, this sensor provides the resolution and reliability your Haltech ECU needs to safely extract maximum power from forced induction setups.

Why You Need This

Standard 1 or 2 bar MAP sensors become a critical bottleneck when you're running serious boost levels. Try feeding a Haltech Elite ECU readings from an inadequate sensor on your 2JZ running 25+ psi, and you'll quickly discover why tuners insist on proper sensor scaling. The ECU can only work with the data it receives — garbage in, garbage out. This 3 bar unit gives your ECU the full picture across the entire boost range, enabling precise fuel delivery and knock-safe timing advance even at maximum boost.

We see this constantly with LS turbo swaps, highly strung RB26 builds, and big-turbo SR20 conversions. Customers arrive with fuelling inconsistencies and poor power delivery, only to discover their original MAP sensor is maxed out and providing useless readings. The Haltech 3 bar sensor transforms these builds, providing the clean, linear signal your ECU craves for consistent power delivery from idle through peak boost.

ECU & System Compatibility

Compatible with the full Haltech Elite and Nexus range, including Elite 550/750/1000/1500/2000/2500 and Nexus R3/R5 systems. The Deatsch Werks connector ensures direct plug-and-play fitment with Haltech's wiring harnesses.

Complete Your Build

Most customers running forced induction setups also require our HT-020400 Boost Control Solenoid for precise wastegate control, and the HT-010200 Air Temperature Sensor for proper charge air monitoring. These sensors work together to give your Haltech ECU complete control over boost delivery and fuelling compensation. All items are in stock at Billy's with fast UK despatch, and our technical team can advise on sensor placement and wiring integration during your build planning.
