Why You Need This

Speed sensing is critical for any serious performance build running Haltech ECU management. Without proper driveshaft speed monitoring, your ECU can't deliver accurate traction control intervention, launch control timing, or meaningful data logging for chassis dyno sessions. Many builders discover too late that their generic speed sensors provide inconsistent signals, causing erratic traction control behaviour or failed launch attempts.

This split collar design solves installation challenges on builds where the driveshaft can't be easily removed. Common applications include LS swap projects in Japanese chassis, RB-powered drift builds, and turbo conversions where driveshaft access is limited. The 8-magnet configuration provides excellent resolution for precise speed calculation, particularly important for high-power builds where traction management makes the difference between grip and wheel spin. We regularly fit these on SR20DET and 2JZ builds running over 400bhp where launch control and anti-lag systems demand accurate speed feedback.

ECU & System Compatibility

Compatible with the full Haltech Elite and Nexus range, including Elite 550, 750, 1000, 1500, 2000, and 2500 models, plus Nexus R3 and R5 systems. Works with any Haltech ECU equipped with speed sensor inputs for traction control and data logging functionality.
