It’s completely brand new inside and out and exactly what your Jeep® Wrangler and Gladiator needs!

Our engineering team took everything learned from the original Pulsar and overhauled it to make it even better while extending coverage for the latest 2021 models! With an all-new case, designed to offer increased rigidity and durability in the most extreme conditions; Pulsar for Jeep JK, JL, and JT continues to push the envelope for inline performance modules. Along with the sturdier case, the PC board has been updated and offers improved reliability and performance for the 3.6L Pentastar. Current part numbers 42450, 42451, 42452 receive new case and board updates, while all-new sku’s 42751 and 42752 offer all-new 2021 model year coverage.

A performance product unlike any other on the market and it’s just been overhauled for even better performance and reliability. Pulsar is an innovative inline module engineered to keep your stock PCM on the Jeep with no PCM swap or unlock required. Enjoy Pulsar as a shift-on-the-fly performance programmer, calibration tool, and throttle sensitivity booster all in one easy-to-use device for the 2018+ applications. We’re also proud to announce that Pulsar for JL/JT can also be used to read and clear Diagnostic Troubles Codes, while still offering tire size and gear ratio calibration, Auto Start/Stop Disable, and TPMS options to adjust or enable/disable.

On top of adding some feature control, Pulsar for 3.6L can add as much as 30hp and 27ft-lbs of torque all from your steering wheel controls with adjustability from Stock, Economy, Tow, and Performance on the fly while driving. You’ll love the improved throttle response and mid-range torque for towing or turning those massive off-road tires down the highway.
