Description
Overview
The DiabloSport S1000 Sprint Module is the simple, plug-and-play solution for GM drivers who want maximum performance without compromises. Designed as an Automatic Start / Stop Override Module for Buick, Cadillac, Chevrolet, and GMC vehicles, it delivers a cleaner, more consistent driving experience by taking control of the factory fuel-saving systems that can rob your engine of power and responsiveness.
At its core, the Sprint Module targets General Motors’ Active Fuel Management (AFM) system. By disabling AFM, it prevents the unwanted cylinder deactivation that many drivers find intrusive and power-sapping. Instead of letting the ECM shut down cylinders in the name of efficiency, the module keeps your engine working the way you want it to — smooth, strong, and ready to respond.
Full V8 Power, All the Time
For newer 2019-2022 GM trucks equipped with Dynamic Fuel Management (DFM), the Sprint Module goes a step further and shuts down this feature as well. The result is an engine that runs in full V8 mode at all times, eliminating the constant cylinder switching that can affect drivability and the feel behind the wheel. Whether you’re towing, cruising, or getting on the throttle, your engine stays in its most capable configuration.
Simple, Plug-and-Play Installation
One of the biggest advantages of the S1000 is how easy it is to add to your setup. It’s engineered as a true plug-and-play device, so you can enjoy the benefits without complicated programming or extensive labor. Compact by design — measuring 2.8 inches in length, 5.5 inches in height, and 1.35 inches in width, and weighing just 1 pound — it’s built to integrate cleanly into your GM gas-powered vehicle.

Fitment
The Sprint Module is designed for gas-powered GM vehicles across the Buick, Cadillac, Chevrolet, and GMC family, with dedicated functionality for 2019-2022 GM trucks that use Dynamic Fuel Management. If your engine relies on AFM or DFM to deactivate cylinders, this module is built to keep those systems from interfering with the way you drive.
For drivers who want their GM engine to perform on their terms — free of cylinder deactivation and always in full-power mode — the DiabloSport S1000 Sprint Module offers a straightforward, effective upgrade backed by DiabloSport’s reputation in performance tuning.
