Part Number Matching
To ensure compatibility with your Dodge, RAM, Chrysler, or Jeep vehicle, it’s critical to match the part number.
- Locate the sticker on your module labeled “Authorized Software Update.”
- Look for the part number, typically prefixed with “Module P/N” and starting with the letter “P” (e.g., P56044673).
- The last two letters of the part number do not need to match exactly.

We offer same-day shipping Monday through Thursday, and on Friday for orders placed before 10:00 AM EST.

Will This Module Work If the Listing Says It’s for a Different Vehicle but the Part Number Matches Mine?

Signs of a Bad ECM or PCM
If your ECM or PCM is failing, you may notice the following issues:
- Engine Performance Problems: Stalling, misfires, or rough idling.
- Starting Issues: The vehicle cranks but doesn’t start, or intermittent starting problems.
- Poor Fuel Economy: A failing module may not optimize fuel delivery.
- Check Engine Light (CEL): Persistent CEL with trouble codes indicating ECM/PCM faults.
- Transmission Issues: Inconsistent shifting (for vehicles with a PCM).
- Erratic or Non-Functioning Gauges: Speedometer, tachometer, or other dashboard indicators behaving abnormally.
If you experience these symptoms, replacing the ECM or PCM may be necessary to restore proper vehicle performance.
What Is Required to Make This Module Plug-and-Play?
To make this module plug-and-play, your vehicle’s VIN must be programmed into it. That’s all!
We offer several options to meet your needs:
- Module Only: For customers who prefer to handle programming themselves.
- Module with VIN Programming: Fully programmed and ready to install in your vehicle.
- Tuning and Customization Services: We have options to add power, or modify the module’s security and DTC/check engine light systems to support retrofit into a completely different vehicle.
Choose the service that works best for your project!
