Core Return Policy
Last updated: April 23, 2026
What Is a Core Charge?
A core charge is included in the price of most Buy-A-ECM orders. This charge covers the cost of the replacement module and is based on the current market price for that specific module at the time of purchase. Core prices vary by vehicle and platform — some modules are more common and cost less, while others are harder to source and carry a higher core charge.
The core charge is 100% refundable when you return your original PCM within 14 days of receiving your tuned replacement.
Core Return Requirements
To receive your full core refund, the returned module must be:
Your original, matching PCM for the vehicle listed on the order
In clean, undamaged condition — no cracked housings, bent pins, or water damage
Free of paint, excessive dirt, or corrosion
Returned within 14 days of receiving your tuned PCM
Cores that arrive damaged, dirty, or painted may be docked or refused. If you're unsure whether your core is acceptable, email us photos at evan@ewaltsautotuning.com before shipping and we'll let you know.
If you experience any issues with your PCM or installation, the 14-day core return window will be extended until the issue is resolved.
How to Return Your Core
Ship your core to:
Ewalt's Auto Tuning
Att: Order #[your order number]
508 3rd St SE
Watertown, SD 57201
Always include your order number on the package or on a note inside the box. For packing and shipping guidance, see our How to Ship Your Module page.
Send Your Core First Option
If you select "You'll Send in Your PCM" at checkout, you ship us your original module first. We flash it and send it back — no core charge and no case relearn required, since you're receiving the same module back.
Tuned PCM Policy
All PCMs are flashed on a per-order basis and are non-returnable once shipped. Defective products are covered by a 1-year warranty replacement.
