The Dakota Digital Universal Speedometer Signal Interface – ELA-SGI-5 delivers unmatched versatility by combining the functions of three calibration tools into one compact module. Designed for modern drivetrain swaps, custom builds, and performance applications, the SGI-100BT allows you to adjust, split, and recalibrate electronic speed signals with precision. It also supports tachometer calibration and even generates gas-style tach signals for diesel conversions, making it an essential tool for accurate instrumentation.

With wide adjustment capability, multiple output options, and compatibility with a variety of sensors, this interface ensures your speedometer and tachometer read correctly—no matter your transmission, tire size, or engine setup. Bluetooth connectivity provides easy programming through a mobile app, while onboard buttons and an LED display offer a convenient alternative for setup without a smartphone.
