Holley EFI 555-100 Computer Aided Design Software — Time-Based Traction Control & Racepak Import

Directly import Racepak driveshaft curve and RPM data into the ECU for seamless integration. The software provides time-based traction control that can be triggered by engine speed and/or driveshaft speed. You can also load crankshaft or driveshaft curves from a previous pass; the imported curve will automatically populate the on-screen graph. Requires a driveline speed sensor to operate, either a wheel speed or a driveshaft speed sensor.
