Overview
Holley EFI Terminator X Active Speed Management Software
Getting a high-powered drag car to hook is the key to low elapsed times and win lights. Whether a small tire radial car or a full out Pro-Mod, all racecars will benefit from Holley's Time-Based Traction Management feature. Designed for Terminator X V3 Build 110 and later, the Time-Based Traction Management is intended for drag racing, standing mile events, or other racing that starts from a stop. Traction management is based on the time from launch vs. engine and driveshaft speed (one or both can be used). The tuner enters several curves that will retard ignition timing and can also enable rev limiting based on the departure of wheel or engine speed from the base curve.
Each Holley EFI Terminator X Active Speed management software purchase allows activation of the traction management features for a single ECU. Once purchased, instructions will be emailed to the purchaser on how to access the feature. Please note that it may take up to an hour for the email to arrive after the order has been placed.
Features:
* Active Speed Management--traction control based on engine speed and/or driveshaft speed
* Import Racepak driveshaft curve and rpm data directly into your ECU
* Import crankshaft or driveshaft curves from previous pass, curve will automatically populate on the graph
* Requires driveline speed sensor, be it wheel or driveshaft speed
