At RIZ ECU, we aim to provide reliable ECU files, professional tuning solutions, and a smooth digital purchasing experience. Since most of our products and services are digital and may be customized according to individual vehicle and ECU requirements, refunds and returns are subject to the conditions outlined below.

1. Digital Products

RIZ ECU primarily provides digital ECU files and online tuning services. These products may include original ECU files, modified ECU files, tuning files, and customized ECU solutions.

Because digital products can be downloaded, accessed, or customized specifically for a customer’s vehicle, they cannot generally be returned in the same way as physical products.

However, we may consider a refund or replacement in the situations described below.

2. Download Problems

If you have completed your purchase but are unable to download or access your purchased ECU file because of a technical problem with our website or download system, please contact our support team.

We will first attempt to resolve the issue and provide you with access to your purchased product.

If the problem cannot be resolved within a reasonable period, your refund request may be considered.

3. Incorrect or Corrupted File

If you receive an ECU file that is corrupted, incomplete, or technically unusable due to an issue on our side, please contact us as soon as possible.

Our team may request relevant information or evidence so that we can investigate the issue.

Where the problem is confirmed, we may provide a corrected/replacement file or, where appropriate, issue a refund.

4. Wrong File or Incorrect Vehicle Information

Customers are responsible for providing accurate vehicle and ECU information when ordering a product or requesting a tuning service.

This may include:

• Vehicle make and model
• Model year
• Engine information
• ECU type
• ECU serial number
• Hardware and software numbers
• Original ECU file
• Other technical information requested by our team

If incorrect information is supplied by the customer and the resulting file or service is therefore unsuitable, the order may not qualify for a refund.

For this reason, please carefully verify all vehicle and ECU information before submitting your order.

5. Customized ECU Files & Tuning Services

Some ECU files are prepared or modified according to the customer’s specific requirements.

Once a customized ECU service has been completed and delivered, refunds may not be available simply because the customer changes their mind or no longer requires the service.

If you believe that the delivered file does not match the service you ordered, please contact us so our technical team can review the situation.

Where an issue is confirmed, we will make reasonable efforts to correct or replace the file where possible.

6. Non-Delivery of Digital Product

If you have successfully completed an order but have not received access to your purchased digital product, please contact us.

We will check the order status and delivery information and attempt to provide access to the purchased file.

If we are unable to deliver the purchased digital product due to an issue on our side, a refund may be considered.

7. Refund Request Period

For digital products and ECU tuning services, refund requests should normally be submitted within 3 days of the purchase or delivery date.

Requests submitted after this period may not be eligible for consideration unless there are exceptional circumstances.

8. Cases Where Refunds May Not Be Available

A refund may not be provided in circumstances including:

• The customer supplied incorrect vehicle or ECU information.
• The customer supplied an incorrect or unsuitable original ECU file.
• The purchased file has already been successfully downloaded and used.
• The customer changes their mind after receiving a customized file.
• The customer requests modifications that were not included in the original order.
• The issue is caused by vehicle hardware, mechanical problems, installation errors, or third-party equipment.
• The customer fails to follow the technical instructions provided with the service.
• The refund request is submitted outside the applicable refund period.

9. How to Request a Refund

If you believe your order qualifies for a refund, please contact the RIZ ECU support team through our Contact Us page.

Please include:

• Your name
• Order number
• Email address used for the purchase
• Vehicle details
• ECU information
• Description of the problem
• Any relevant screenshots, files, or other evidence

Providing complete information will help us investigate your request more quickly.

10. Refund Review Process

Every refund request is reviewed individually.

Our team may first attempt to resolve the issue by providing technical assistance, correcting the file, or supplying a replacement where appropriate.

If a refund is approved, the refund will normally be processed through the original payment method, subject to the processing time and policies of the relevant payment provider.
