Restore Peak Performance to Your 3.6L Pentastar Engine
Is your 2015 Chrysler 300, Dodge Charger, or Challenger suffering from mysterious and frustrating issues? Unexplained check engine lights, rough idling, stalling, or a complete failure to start can often be traced back to a failing Engine Control Module (ECM). The ECM is the brain of your vehicle, managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it starts to fail, the symptoms can be widespread and difficult to diagnose. This replacement engine computer is the definitive solution to get your vehicle running reliably again.
This unit arrives at your door completely pre-programmed to your vehicle’s specific Vehicle Identification Number (VIN) and current mileage. This critical service means you can skip the expensive trip to the dealership for programming. It’s a true plug-and-play solution designed for a straightforward installation. Simply disconnect the battery, swap the modules, reconnect the battery, and you’re ready to go. You’ll restore the precise engine management your vehicle had when it left the factory.
From the Diagnostic Bay
We had a 2015 Dodge Charger with the 3.6L come in that was giving the owner fits. The car would run perfectly for days, then suddenly stall at a stoplight and refuse to restart for an hour. There were no consistent trouble codes, just a random collection of communication errors that would disappear after a reset. We checked wiring harnesses, sensors, and power grounds for hours. On a hunch, we put a scope on the CAN bus network and noticed signal degradation when the engine bay was hot. We applied heat directly to the ECM, and the communication signals went haywire, duplicating the stall condition. A faulty processor in the original ECM was failing under thermal stress. Installing one of our pre-programmed modules solved the problem instantly and permanently. The customer was thrilled to have their reliable car back without a massive dealership bill.
Is Your 2015 Chrysler 300 ECM Failing?
A faulty engine computer can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your ECM needs replacement. This module is the correct fix for these common problems.
- ✔ Check Engine Light: The check engine light (CEL) is on, and you may have codes related to sensors, ignition coils, or internal module failure.
- ✔ Engine Stalling or Misfiring: The engine may stall unexpectedly, misfire, or run very rough, especially as it warms up.
- ✔ No-Start Condition: The engine cranks but will not start, often due to the ECM not firing the ignition coils or fuel injectors.
- ✔ Poor Fuel Economy: A significant and sudden drop in gas mileage can be caused by incorrect fuel and air mixture calculations from a failing ECM.
- ✔ Transmission Issues: The ECM communicates with the transmission controller. A bad ECM can cause harsh shifting, failure to shift, or incorrect gear selection.
- ✔ Intermittent Problems: Issues that come and go with temperature changes are a classic sign of internal electronic failure within the computer.

Frequently Asked Questions
Do I need to do any programming after I install this?
No. This engine computer comes fully programmed to your vehicle’s VIN and mileage. It is a true plug-and-play installation. No further programming or dealer visits are required.
What information do you need from me to program it?
We will need your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. You can typically provide this during the checkout process. The VIN is essential for loading the correct software and security keys.
Is this compatible with my all-wheel drive (AWD) model?
Yes, as long as your vehicle is a 2015 Chrysler 300, Dodge Challenger, or Dodge Charger with the 3.6L engine, this module is programmed to work with all drivetrain configurations, including both RWD and AWD.
Will this fix my specific trouble codes?
This module will resolve issues and codes that are directly caused by a failing ECM, such as internal processor faults or driver circuit failures. However, it will not fix problems caused by faulty external sensors, wiring, or other mechanical components. It’s crucial to ensure the ECM is the root cause of your issue before ordering.
How difficult is the installation?
For someone with basic mechanical skills, the installation is straightforward. It typically involves disconnecting the vehicle’s battery, unplugging the electrical connectors from the old ECM, unbolting it from its bracket, and then reversing the process with the new unit. We always recommend consulting a repair manual or having a qualified technician perform the installation if you are not comfortable doing it yourself.
