Superchips Pulsar Inline Module for 2018-2023 Jeep Wrangler JL and 2020-2022 Gladiator JT 3.6L V6 - 4876

The Superchips Pulsar 4876 is an inline performance module for the 2018-2023 Jeep Wrangler JL and 2020-2022 Gladiator JT with the 3.6L Pentastar V6, including eTorque. It plugs in between the factory PCM and the harness, adds up to 30 hp and 27 lb-ft, and corrects speedometer and shift points for larger tires and new gears, with no PCM unlock or swap.

Power levels switch from the factory cruise control buttons while driving, across Tow, Economy and Performance settings, and a built-in pedal booster sharpens throttle response. Unplug the module and the Jeep is back to stock.

Installation and limitations

Installation is plug-in at the PCM connectors with no cutting or splicing; the module is removable and leaves the factory calibration untouched. Not for use in California.

If you only need tire and gear calibration without the power, the Superchips Flashcal+ SC-MOD does that from your phone. High-mileage 3.6L? The Superchips high output coil set 4445-CP6 is a common pairing.

Frequently asked questions

Does the Pulsar flash or unlock the PCM?

No. It sits inline between the PCM and the harness and the factory calibration is never written to, so there is no unlock, no PCM swap and no dealer flash to undo.

Will it work on my eTorque Wrangler?

Yes. The 4876 supports the 3.6L with or without eTorque. It does not support the 2.0L turbo, 3.0L EcoDiesel or 6.4L.

Can it fix my speedometer after 35s and a re-gear?

Yes. Tire size and gear ratio (2.00 to 5.99) are both adjustable, which corrects the speedometer, odometer and shift points.

How do I change power levels?

With the factory cruise control buttons on the steering wheel, while driving. No handheld or phone is required.
