JMS Traction Control Module

JMS TractionMAX: Precision Traction Control for High-Horsepower Vehicles

When big power meets pavement, the difference between a clean launch and a smoky tire spin often comes down to how intelligently your traction control system works. JMS Chip & Performance, a Florida-based manufacturer renowned for their electronically controlled performance modules, addresses this challenge head-on with their TractionMAX traction control module — an aftermarket solution engineered specifically for drivers who demand more from their vehicles than factory electronics can deliver.

What Makes the JMS TractionMAX Different?

At its core, the TractionMAX is a plug-and-play traction control device built around a deceptively simple concept: give the driver real-time, granular control over both throttle feel and traction intervention in a single compact module. Unlike a basic on/off traction defeat switch, the TractionMAX features a dual-dial system that lets drivers independently tune two key parameters. The PEDAL dial governs throttle blade enhancement — ranging from full torque reduction all the way to maximum enhancement — while the TIME dial fine-tunes how aggressively the traction system intervenes during acceleration. As Ford Muscle noted, the dual-dial allows you to adjust "the throttle & traction response to fit your needs, giving you extra control at your fingertips."

Installation is equally straightforward. The unit plugs in-line between the vehicle's pedal position sensor and the factory wiring harness — no cutting, splicing, or laptop required. JMS also includes wiring for a toggle switch or power control button, giving owners flexible options for engaging and disabling pre-tuned traction settings on the fly.

Built for Serious Builds, Street to Strip

The TractionMAX was engineered with high-horsepower, traction-limited vehicles squarely in mind — including forced induction builds, OE performance cars, and front-wheel-drive platforms. JMS has developed vehicle-specific fitments spanning an impressive range of platforms. GM enthusiasts will find coverage across Corvette C7 and C8 models, Camaro ZL1, Corvette ZR1, and virtually all LS- and LT-powered GM trucks and SUVs dating back to 2007. Ford fans aren't left out either, with fitments available for the Mustang Shelby GT500, F-150 Raptor, Bronco, and many more. Hyundai, Kia, Genesis, Jeep, Land Rover, and even Tesla owners can also find compatible TractionMAX units in the lineup.

A standout feature for manual transmission drivers is the automated traction lockout: the TractionMAX controls the rate of acceleration to prevent wheel spin during a first-gear launch, then automatically unlocks normal throttle function for the following 20 seconds. This makes it equally useful for drag strip launches and spirited street driving.

Quality, Warranty, and Made in the USA

Every TractionMAX unit is waterproof, backed by a lifetime warranty, and designed and assembled in the USA — a level of build quality and brand confidence that sets JMS apart in the crowded aftermarket electronics space. The module is compatible with both factory and aftermarket tunes, so it integrates cleanly into modified builds without interfering with existing ECU calibrations.
