Torque management on a Haltech Nexus can only react to what it can measure. The Wiring node is where the function's physical connections are set up in NSP.

Torque Management is the Haltech function that trims engine power to help keep wheelspin and launches under control. Like other functions in NSP, it has a Wiring node for its physical connections, alongside its tuning tables.

Detailed documentation for this node is still limited, so rather than guess at specific options, here's the practical side. Torque management strategies are built around measured signals, for example engine speed, driveshaft speed from a driveshaft RPM sensor, ride height, or a trim knob. Before touching the tables, make sure each sensor or switch the strategy relies on is wired, assigned and reading correctly in NSP. A strategy fed by a bad signal is worse than no strategy.

From there, the tuning side is covered in torque management, TM driveshaft RPM target and TM knob calibration. Setting up torque management on a new car? Ask us and we'll help you plan the wiring for your build.
