Holley Terminator X EFI Bluetooth Module
Unlock the full potential of your Terminator X EFI system with this Holley Bluetooth module for wireless tuning and real-time engine monitoring. This advanced module connects via Bluetooth to your Terminator X or X Max ECU, allowing you to adjust and optimize your engine directly from your iOS or Android smartphone. It can be used in conjunction with Holley digital dashes. Built-in EFI Wizard allows for basic tuning, advanced tuning, and input/output control, as well as customizable data monitors. You can quickly make tuning adjustments, such as changing the rev limiter RPM or adjusting idle settings, without firing up a laptop. Customizable live dash display mode turns your phone into a digital dash, utilizing your phone’s built-in accelerometer to display vehicle speed. The simple module has a pairing button, a status LED, and an SD card slot for future expansion. Supplied with a Mizu-style CANbus connector and a long cable, makes installation easy and secure anywhere in the cab.
