Is Your 2015 Challenger, Charger, or 300 Acting Up?
There’s nothing more frustrating than when your modern Mopar starts having electrical gremlins. One moment it’s running perfectly, the next you’re dealing with a check engine light that won’t go away, rough idling, or even a no-start condition that leaves you stranded. These intermittent and confusing issues often point to one central component: a failing Engine Control Module (ECM), the brain of your vehicle’s 3.6L Pentastar engine.
The ECM is responsible for managing everything from fuel injection and ignition timing to transmission shift points and emissions controls. When it begins to fail, the symptoms can be widespread and difficult to diagnose. You might replace sensors, spark plugs, and coils, only to have the problem return. This is because the component giving the commands is the one that’s malfunctioning.
From the Diagnostic Bay
We once had a 2015 Dodge Charger 3.6L come into the shop with a ghost of a problem. The owner complained of random stalling at red lights and an intermittent misfire code (P0300) that would appear and disappear. He had already spent a small fortune on new ignition coils and injectors at another shop. We spent hours checking wiring and live data, but everything looked normal. Finally, on a hunch, we put a scope on the injector control signals directly from the ECM. We found that the signal to cylinder 3 would drop out randomly when the engine bay was hot. The problem wasn’t the injector; it was the ECM itself. A replacement, pre-programmed 2015 Challenger Engine Computer had the car running perfectly in under 30 minutes. It’s a classic case of the symptoms not always pointing directly to the source.
Common Symptoms of a Failing 2015 3.6L ECM
- ✔ Check Engine Light: You may see persistent codes, especially communication codes (like U0100) or multiple, unrelated sensor codes that come and go.
- ✔ No-Start Condition: The engine cranks but refuses to start, often due to a lack of fuel or spark command from the ECM.
- ✔ Poor Performance & Fuel Economy: Your vehicle may feel sluggish, hesitate on acceleration, or get noticeably worse gas mileage as the ECM fails to manage the engine efficiently.
- ✔ Engine Stalling: The engine may stall for no apparent reason, either while driving or at idle, and may or may not start back up immediately.
- ✔ Erratic Transmission Shifting: The ECM works with the transmission control module. A faulty ECM can cause harsh shifts, delayed engagement, or the transmission getting stuck in one gear (limp mode).
- ✔ Misfires and Rough Idle: The computer may fail to correctly control ignition timing or fuel injectors, leading to a shaky idle and misfire codes.
Your Direct-Fit 2015 Challenger Engine Computer Solution
Replacing the ECM on these vehicles isn’t as simple as swapping a part. The module is coded specifically to your car’s Vehicle Identification Number (VIN) and contains vital security information for the anti-theft system. A used module from another vehicle simply will not work without an expensive trip to the dealership for programming—and some dealers are unable or unwilling to program used modules.
This is the definitive solution. We take the hassle and expense out of the equation. When you order this module, we program it specifically for your vehicle using the VIN you provide at checkout. It arrives at your door ready for a true plug-and-play installation. Simply disconnect the battery, swap the modules, reconnect the battery, and start your car. You’ll restore the performance and reliability you expect from your vehicle without the need for any additional programming or dealer visits.

Frequently Asked Questions
Do I need to have this computer programmed by a dealer?
No. This is the main benefit of our service. The engine computer will arrive at your door fully programmed to your vehicle’s specific VIN. It is a plug-and-play installation, requiring no further software work.
What information do you need from me?
We require your vehicle’s 17-digit VIN (Vehicle Identification Number) during the checkout process. This ensures we can program the module with the correct software and security information for your exact car.
Where is the ECM located on my 2015 Challenger/Charger/300?
On these 3.6L models, the ECM is typically located in the engine bay on the passenger side, near the firewall or shock tower. It is a silver metal box with several large electrical connectors.
Will this fix my specific check engine light codes?
This module will resolve issues and codes that are directly caused by a faulty ECM. This includes communication codes, internal processor fault codes, and driver circuit codes. It’s important to ensure proper diagnosis has been performed, as this part will not fix issues caused by faulty sensors, wiring, or other mechanical components.
Is any other setup required after installation?
In most cases, no. The unit is plug-and-play. However, like with any major computer replacement, it’s good practice to let the vehicle idle for a few minutes after the first start to allow all systems to re-synchronize.
