Haltech HT-011310 GPS Speed Input Module 300mm 5000PPK 10Hz Anti-Drift DTM-3

Vehicle Fitment

• Universal - compatible with all Haltech ECU platforms including the Nexus S2, S3, R3, R5, Elite 550, 750, 1500, 2500, and plug-in ECU series via SPI or DPI (Synchronous or Digital Pulsed Input) channels
• Suitable for any application requiring a digital vehicle speed signal where a traditional wheel speed sensor is impractical or unavailable - including drag cars, drift builds, custom chassis, and dyno setups
• Compatible with any ECU or data logger accepting a 0-12V digital pulsed speed input at 5000 pulses per kilometre

Fitment Notes

• Connects to the ECU via a Synchronous Pulsed Input (SPI) or Digital Pulsed Input (DPI) channel - confirm channel availability on your specific ECU before installation.
• Default calibration is 5000 pulses per kilometre (5000 PPK) - verify ECU software calibration matches this value for accurate speed readings.
• The GPS antenna must have a clear view of the sky for reliable signal acquisition. Performance may be reduced in deep tunnels, dense urban canyons, or under heavy electromagnetic interference, though the built-in pulse compensation and anti-drift technology mitigate most signal loss scenarios.
• Module harness length is 300mm - plan installation location accordingly to ensure reach to the ECU input and antenna placement with sky visibility.

Features

• Converts GPS satellite speed data into a 0-12V digital pulsed output at 5000 pulses per kilometre, providing a clean speed signal to the ECU without a wheel speed sensor or driveshaft pickup.
• 10Hz GPS update rate delivers speed data refreshed 10 times per second for responsive traction control, launch control, and speed-based ECU functions.
• High accuracy of ±0.3% deviation ensures reliable speed readings suitable for data logging, traction control strategies, and speed-based ignition or fuel corrections.
• Anti-GPS Drift technology prevents erratic speed readings caused by GPS signal degradation - maintains stable output during brief signal interruptions.
• Pulse Compensation in tunnel maintains a plausible speed signal when GPS lock is temporarily lost, preventing ECU input errors during tunnel transit.
• 0-12V pulsed output is compatible with Haltech SPI and DPI inputs as well as most other ECU digital pulsed speed inputs.
• Compact 300mm module design for flexible mounting in tight engine bays, dashboards, or roll cage structures.
• Includes GPS antenna and matching male Deutsch DTM-3 connector with pins - ready to install without sourcing additional hardware.

Product Description

The Haltech HT-011310 GPS Speed Input Module provides a reliable digital vehicle speed signal for applications where a traditional wheel speed sensor or driveshaft pickup is unavailable, impractical, or has been removed. It uses GPS satellite data to calculate vehicle speed and converts it to a 0-12V pulsed digital output at a fixed calibration of 5000 pulses per kilometre - directly compatible with Haltech ECU SPI and DPI inputs. The 10Hz update rate and ±0.3% accuracy deviation make it suitable for traction control strategies, launch control, speed-based ignition/fuel corrections, and high-resolution data logging.

The module incorporates Anti-GPS Drift technology to prevent erratic speed outputs during signal degradation, and Pulse Compensation to maintain a stable speed signal during brief tunnel or signal-blocked conditions. This makes it more reliable than basic GPS modules in real-world motorsport environments. The included GPS antenna, Deutsch DTM-3 connector, and pre-terminated 300mm harness make installation straightforward. The antenna requires a clear sky view for lock acquisition - plan mounting location to maximise satellite visibility while protecting the module from excessive heat or vibration.
