The Term X Bluetooth Module by Holley (MPN 558-483) is a wireless connectivity solution designed for modern engine management and vehicle tuning applications. Built for enthusiasts and professional mechanics who demand real-time data access and remote diagnostics, this compact module eliminates the need for wired connections to aftermarket ECUs and tuning platforms. Whether you're running a standalone fuel injection system, supercharger management setup, or advanced ignition control, the Term X delivers seamless Bluetooth integration for both street and competition vehicles.

This module leverages robust wireless protocol technology to establish stable communication between your engine management system and mobile devices or laptops without signal dropout during critical tuning sessions. The compact form factor measures 4.5 x 3.5 x 5 inches and weighs 0.325 lbs, allowing installation in tight engine bays alongside other control modules without compromising wiring organization or heat management.

Mechanics and tuners benefit most from the Term X when performing on-the-fly adjustments during dyno sessions, cold-start calibration, or street testing with real-time data logging and remote diagnostics. The plug-and-play design integrates directly with Holley EFI systems and compatible standalone platforms to provide live fuel trim data, air-fuel ratio readings, and diagnostic trouble codes.
