This purchase activates Holley's Time-Based Traction Management feature on one Terminator X ECU running V3 software, build 110 or later. It is intended for drag racing, standing mile events and other racing that starts from a stop. Traction management compares time from launch against engine speed, driveshaft speed or both, and the tuner enters curves that retard ignition timing and can enable rev limiting when wheel or engine speed departs from the base curve.
Key Features:
- Active speed management: traction control based on engine speed and/or driveshaft speed
- Import Racepak driveshaft curve and RPM data directly into the ECU
- Import crankshaft or driveshaft curves from a previous pass; the curve populates on the graph automatically
