Is Your 3.6L Pentastar Running Rough? It Could Be the ECM.
If you’re experiencing frustrating issues with your 2015 Chrysler 300, Dodge Charger, or Dodge Challenger, the root cause might be the very brain of your engine: the Electronic Control Module (ECM). A failing ECM can manifest in a wide range of baffling symptoms, from a simple check engine light to a car that refuses to start. This can lead to incorrect diagnoses, wasted money on unnecessary parts, and significant downtime. Don’t let a faulty computer keep your powerful Mopar off the road. This direct-fit, pre-programmed engine computer is the definitive solution to restore your vehicle’s performance, reliability, and efficiency.
Solving Your Engine Problems with a Pre-Programmed 2015 Chrysler 300 ECM
The main challenge with replacing an ECM is the complex programming required to sync it with your specific vehicle. Traditionally, this meant a costly trip to the dealership for specialized tools and labor. We eliminate that step entirely. We flash this module with your vehicle’s unique Vehicle Identification Number (VIN) and current mileage before it ships. The result is a true plug-and-play component. Once it arrives, you simply install it, and your car’s systems will recognize it instantly, restoring all original functions without any additional programming or dealer intervention.
From the Diagnostic Bay
We had a 2015 Charger with the 3.6L engine come in with a persistent P0344 code (Camshaft Position Sensor ‘A’ Circuit Intermittent). The owner had already replaced the sensor twice. We checked the wiring harness for continuity and even scoped the signal at the sensor – it was perfect. The signal going *into* the ECM was clean, but the computer kept flagging the code and causing rough idling. After exhausting all other possibilities, we connected a known-good ECM. The code vanished instantly, and the car ran perfectly. It’s a classic case of the ECM’s internal processor failing, a reminder that sometimes the brain, not the sensor, is the culprit.
Common Symptoms of a Failing ECM

Frequently Asked Questions
Is this 2015 Chrysler 300 ECM truly plug-and-play?
Yes, absolutely. We program the module using the VIN you provide during checkout. This ensures that when you receive it, it is fully synchronized with your vehicle’s security system (SKIM) and other modules. No further programming is required.
What information do you need from me to program it?
We require your vehicle’s 17-digit VIN to ensure a perfect software match. You can typically find this on your driver’s side dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
Where is the ECM located on my vehicle?
On the 2015 Chrysler 300, Charger, and Challenger with the 3.6L engine, the ECM is typically located in the engine bay, on the passenger side, near the firewall or shock tower. It’s a silver metal box with several large electrical connectors.
Will this fix my specific problem?
This module will correct any issues directly caused by a faulty ECM. While the symptoms listed above are common indicators, we always recommend a proper diagnosis by a qualified technician to confirm the ECM is the point of failure before ordering.
Do I need to return my old engine computer?
This purchase does not require you to send back your original part. There is no core charge associated with this item, allowing you to complete your repair without the hassle of return shipping.
