Elite 2500 T Overview

The Elite 2500 T is the Elite 2500 with Haltech's torque management built in, aimed at drag and high-power cars where traction decides the result. Here is what it includes and what to know before you buy one.

What the "T" means

The Elite 2500 T is built on the top-level Elite 2500 platform and adds torque management. Torque management compares driveshaft or engine speed to a target you set and pulls timing or cuts cylinders to keep the car on that path. It's built for drag racing and other high-power cars where wheelspin costs time. If you don't need that, the regular Elite 2500 covers everything else.

Every feature is enabled from the start. There are no paid unlocks.

About the waterproof rating

The case is rated IP67, but only when it's properly sealed. That means the pocket cover must be fitted, or the USB port must be sealed with the waterproof USB extension cable and waterproof USB cap, which are sold separately. If you plan to mount the ECU in the engine bay, budget for these.

Wiring it up

For a custom install, the Elite 2500 and 2500 T premium universal harness is our usual starting point. For Coyote swaps, there are ready-made 2500 T harness kits such as the Coyote 5.0 late cam solenoid kit. Connector pinouts are covered in our 26-pin and 34-pin Elite 2500 pages.
