Bluesky MISC HYP-730120 Hypertech In-Line Speedometer Calibrator Module

The Hypertech 730120 In-Line Speedometer Calibrator Module is a dedicated inline correction device designed to restore accurate speedometer and odometer readings after installing non-stock tire sizes or changing rear axle gear ratios. This compact module installs directly into the vehicle's instrument cluster wiring harness — no handheld programmer or laptop tuning software required for everyday use.

Key Features:

• Corrects speedometer and odometer readings caused by non-stock tire sizes or rear gear ratio changes
• Ideal for vehicles whose factory computers do not support tire size or gear ratio recalibration natively
• Also covers tire sizes and gear ratios that fall outside the adjustment range of standard aftermarket programmers
• Programmed via USB cable connection to a PC — simply enter the new tire height and/or rear gear ratio
• No limitations on tire height increases or gear ratio changes
• Installs inline at the instrument cluster connector behind the dash — no cutting or splicing required
• Quick installation — most installs completed in minutes
• Sold individually

Installation is straightforward: connect the module to a PC via USB to input your tire and gear specifications, then unplug the factory instrument cluster connector, snap in the Speedometer Calibrator Module, and reconnect. The result is accurate speed and distance readings calibrated to your actual tire and gear setup.
