Our warranty covers all ECU repairs for 5 years from the original purchase date on the Sales Invoice. In exchange, the 5-Year Warranty begins from the day that we receive your old unit at our location.

Our warranty does not cover any damage to the repaired or exchanged ECU, that results from improper installation, accident, exposure to water or fire, collision, abuse, misuse, natural disaster, insufficient or excessive electrical supply, abnormal mechanical or environmental conditions, or any unauthorized disassembly, repair, or modification.
If any security seals are tampered with, the warranty will be cancelled. Contact us before you open the ECU in the case that you want to install a performance chip.

The warranty will not be valid without a copy of the Sales Invoice. Your warranty is not transferable if the car is sold to another person or entity.

We are not responsible if a car's warranty with the manufacturer is voided by using replacement parts supplied by us.




Warranty claims cannot be resolved through the phone. Warranty claims must be submitted using the weblink provided by us.

Units need a warranty approval number (RMA) which we will supply AFTER the Warranty Form is filled out and reviewed by our technicians.

The technician will determine any of these 3 different courses of action to respond to the claim within 1-2 business days of the form being submitted:

  • We’ll ask to send in the unit for a warranty check. (Usual turnaround time of 5 to 10 business days applies)
  • We’ll replace the unit by sending another control unit (Usually 5 to 10 business days to ship the part.)
  • We’ll respond by email a solution that does not require to go through the warranty process (1-2 business days)

Units received for warranty check without permission from the technician or warranty number (RMA) will be shipped back to the sender's address via UPS ground with $100 insurance.

In the case of a unit tested under warranty and found to be in perfectly working condition, another $149 testing fee will be charged plus the return shipping cost to the customer.

Otherwise, if found defective we will repair or replace the unit free of charge and we will cover the ground shipping for USA customers only. International customer must pay for their own shipping charges.

If the technician determines that an exchange will solve the problem, we will need to collect a tester deposit before sending another unit for replacement. We will cover USA ground shipping for both units. International customer must pay for their own shipping charges.

The tester deposit will be returned to the customer in full after the defective (or the exchange unit) is returned to us without un-rebuildable defects.

Specialized ECU Repair will not be responsible for garage storage fees, labor charges, car rental fees, towing charges or any other type of fee charged to the customer or mechanic from any third party, or repair shop, during or after the time of the warranty process.




Testing, Programming and Shipping Fees are Non-Refundable.

On repairs or exchanges, no refunds will be issued unless we have exhausted all the possibilities to resolve the problem or warranty matter through a repair, or replacement. It is the responsibility of the owner to consult with us about any problems or warranty issues, before going to a third party for a diagnosis or a resolution.

Exchanged units can be returned to receive a refund minus a 35% Re-stocking fee within 10 business days of receiving the unit.

Repaired ECU's can be refunded 100%.

If we approve a refund, please allow up to 5 business days for us to process the refund.



Most repairs have a 5 to 7 day. Due to seasonality and an increase in workload turnaround time can be up to 10 business days. Depending on the severity and complexity of the damage in the ECU, some repairs can take more time. Specialized ECU Repair will not be responsible for garage storage fees, labor charges, car rental fees, towing charges, or any other type of fee charged to the customer from any third party, or repair shop, during or after the time of the repair.

Upon arrival of the ECU to our shop, the ECU will be inspected and tested before we begin to repair it. If after testing the ECU we find that the unit is damaged beyond repair, due to fire damage, water damage, or a defective CPU, the customer will be contacted immediately and advised to get a replacement ECU. In such a case, an ECU replacement quote will be provided to the customer before we go any further.

Since many of the ECUs that we repair are over 15 years old and, their old components can fail at any given time, each ECU repair will also have their most important parts updated with new components in order to ensure the length of the 5 Year Warranty.




Cores must be returned to our office within 7 days of the delivery date in order to receive the refund of the core charge. You may be subject to additional charges, in addition to a cancelled warranty, if you do not return your old ECU within 7 days of receiving your new rebuilt ECU.

You must make your own shipping arrangements to return the core.

ECUs returned in non-rebuildable condition, such as water-damaged, fire-damaged or manipulated ECUs, may receive a partial refund, or no refund at all.

Once a core is received because of an exchange they are rebuilt and become part of our stock.




UPS is our preferred, and only, mail carrier.

UPS Ground costs $19 within the United States. These packages takes between 1-6 days to reach their destination depending on your location.

UPS 3rd Day - $29

UPS 2nd Day Air - $39

UPS Next Day Air - $79

Shipments going to Puerto Rico, Guam, Alaska and Hawaii usually cost $49. Shipping & Handling Standard to Canada costs $49. For International shipments, we only use UPS Express Saver 5-Day delivery for $120 since we have noticed that this UPS service is easier to pass through customs.

All of our shipments are automatically insured for $100. It is the responsibility of the customer to inform us in writing if they wish us to insure the package for the full price of the contents of the box. The customer will have to pay the additional cost of the insurance. We are not responsible for lost or damaged packages after they are shipped from our office.

Before you pack your ECU to send it to us, wrap it with cushioning material (bubble wrap, foam peanuts or paper). This will avoid damages to the unit during shipping.

Please, use the smallest box possible when you send your ECU to us. These are some suggestions:
