Return Policy – ECM Engineering LLC

1. General Conditions for Returns

• Returns are accepted only within the first 15 calendar days from the date the customer receives the product.
• The ECM (Engine Control Module) must be in good physical condition, showing no signs of damage, mishandling, alterations, burns, moisture, or unauthorized modifications.
• ECMs that have been installed and used are subject to a technical inspection before any return or partial refund can be approved.

1. Partial Refund for Voluntary Returns

• If a customer wishes to return an ECM for reasons other than manufacturing defects or malfunctions, and the product has been used, they may receive up to 50% of the purchase price as a refund, provided that:
  • The return is requested within 15 days of receipt.
  • The ECM is in acceptable condition and can be reprocessed or reconditioned for future use.
• Important: Each module sold by ECM Engineering LLC is custom-programmed using the customer’s specific serial number or VIN. This individualized programming process incurs non-recoverable operating and software licensing costs. Therefore, any voluntary return request will be subject to a fixed deduction of 50% of the total product value.
