Hypertech 730105 In-Line Speedometer Calibrator Module for Nissan Titan & Armada

The Hypertech 730105 In-Line Speedometer Calibrator Module is a plug-in correction device engineered to restore accurate speedometer and odometer readings after a tire size upgrade or rear gear ratio change. When non-stock tires or gears are installed, the vehicle's computer continues to calculate speed based on the original stock tire diameter — resulting in inaccurate readings. This module corrects that discrepancy quickly and without permanent modifications.

Key Features:

• Corrects speedometer and odometer for non-stock tire sizes and/or aftermarket rear gear ratios
• No limitations on tire height or rear gear ratio combinations
• Ideal for vehicles whose factory computer does not support tire size or gear ratio recalibration, or require correction beyond the range of standalone programmers
• Installs inline with the factory instrument cluster wiring harness — no cutting or splicing required
• Does not interfere with OEM diagnostics or safety systems
• Reads, displays, and clears diagnostic trouble codes (DTCs)

What's Included:

• Hypertech In-Line Speedometer Calibrator Module
• USB cable
• PC programming software for entering tire height and gear ratio settings

Installation Overview:

Connect the module to your PC via the included USB cable and enter your new tire height and/or rear gear ratio. Then disconnect the factory connector behind the instrument cluster, snap in the calibrator module, and reconnect. Installation requires basic hand tools including a Phillips screwdriver and a 7mm socket.

The Hypertech 730105 is a straightforward solution for truck and SUV owners who have upgraded their tires or differential gears and need an accurate, hassle-free speedometer recalibration.
