Auto Computer Specialist (ACS)

---

Due to the highly specialized, technical, and often irreversible nature of ECU-related services, ACS maintains a strict no-refund policy once service work has begun.

Upon receipt of your module, our technicians immediately allocate diagnostic time, proprietary software licenses, specialized equipment, and in some cases internal components to begin the service process. Because these resources are committed at the start of the repair workflow, refunds cannot be issued after service initiation.

This policy ensures operational fairness and allows ACS to continue maintaining the professional standards, technical accuracy, and turnaround times our customers rely on.

The Following Services Are Strictly Non-Refundable

1. Repair & Rebuild Services
   Repair and rebuild services are performed based on the Diagnostic Trouble Codes (DTCs) and vehicle symptoms provided by the customer. ACS does not perform full vehicle diagnostics, therefore services are completed according to the information submitted at the time of order.
2. Programming Services
   Once software, firmware, or calibration data has been written to a control module, the process is permanent and cannot be reversed, making programming services non-refundable.
3. Testing Services
   Testing utilizes professional simulation equipment and technician labor. Even if no internal fault is identified, the service has been completed and remains non-refundable.
4. Cloning & Data Transfer
   Data cloning and transfer services are unique to each individual module. Once performed, the data transfer cannot be undone or reassigned.
5. Shipping & Handling
   Shipping services are considered completed once the package is scanned by the carrier, regardless of delivery outcome or transit conditions.
6. Tampered or Altered Units
   Refunds will not be issued for any ECU that has been opened, modified, tampered with, or physically damaged after it has been returned to the customer. 

OEM Replacement Units Only Returns are accepted exclusively for Remanufactured Replacement Units and must meet all conditions listed below.

Eligible Return Requirements

To qualify for a return:

• The return request must be initiated within 14 days of delivery.
• The unit must be unused, uninstalled, and in its original condition.
• All ACS warranty seals and tamper labels must remain fully intact.
• The unit must not have been powered, energized, programmed, or installed in any vehicle.

If these conditions are not met, the unit will be subject to a 60% restocking fee. This restocking fee also applies to returns resulting from:

• Incorrect diagnosis
• Ordering the wrong part
• Customer installation error
• Vehicle issues unrelated to ECU failure
  

Diagnostic Trial Prohibition

ACS products may not be used for trial-and-error diagnostics.

• Installing a replacement ECU simply to “test if it fixes the problem” without confirming ECU failure or resolving the underlying root cause violates company policy.
• Returns submitted under these circumstances may be denied or restocked at partial value. 

To ensure accurate processing, efficient repair workflows, and minimal delays, customers are required to provide the following before submitting a unit for service:

1. Completed ACS Service Form Every shipment must include the official ACS Service Request Form, filled out completely and accurately.
2. Removal of Aftermarket Tunes Any aftermarket flash files, performance tunes, or third-party software must be removed prior to sending the ECU. ACS does not preserve, restore, or guarantee the retention of aftermarket calibrations or non-OEM programming during the service process. 

Turnaround time begins only after both the ECU and completed service documentation are received.

Typical service timelines are as follows:

• Repair / Rebuild Services (Excluding A50/T14 modules)
  Estimated turnaround: 3–5 business days
• Remanufactured Replacement Units
  Estimated turnaround: 1–5 business days
• Programming & Cloning Services
  Estimated turnaround: 1–5 business days
• Wire Harness Restoration
  Estimated turnaround: 10–15 business days

Please note that turnaround times are estimates and not guarantees. Delays may occur due to:

• Technician workload
• Parts availability
• Complex or previously tampered units
• Shipping delays or unforeseen service complications
  

Customers are encouraged to monitor shipment tracking and allow reasonable downtime for service completion. 

All ECU testing is conducted using professional-grade diagnostic simulators and proprietary testing equipment, requiring specialized technician expertise regardless of outcome.

Testing services are billable and non-refundable. Standard Testing Rates

1. Gasoline ECUs  $148.88
2. Light / Medium Duty Diesel ECUs  $188.88 – $288.88
3. Heavy Duty Diesel ECUs  $288.88 – $488.88

If the prepaid amount exceeds the final testing cost, any remaining balance will be promptly refunded to the original payment method. All ECU testing is performed using professional-grade simulation tools and requires skilled technician labor, regardless of whether faults are found. These services are billable and non-refundable.

Standard testing fees include:

• Gasoline ECUs: $100.00 
• Light/Medium-Duty Diesel: $148.88 – $248.88 
• Heavy-Duty Diesel: $248.88 – $448.88
   

If your prepaid amount exceeds the final testing fee, any overage will be refunded promptly.

This warranty policy applies to all services provided by Auto Computer Specialist, including ECU repair, remanufactured ECU replacement, ECU programming, VIN cloning, diagnostics, and wire harness restoration. 

Our goal is to provide reliable electronic repairs while clearly defining what is and is not covered under warranty.

ACS proudly offers a Limited Lifetime Warranty with Unlimited Mileage on qualifying services performed on or after June 15, 2022.

This warranty applies to:

• ECU Repair and Rebuild Services
• Remanufactured Replacement Units (for qualifying ECUs)
  
  

The warranty is valid only for the original purchaser and is non-transferable. 

The ACS Lifetime Warranty provides the following protections:

1. Coverage of Original ACS Work
   The warranty covers only the specific repair or service originally performed by ACS.
2. Single Warranty Repair Attempt
   Units are eligible for one in-warranty repair or service, provided the root cause of failure has been corrected.
3. Replacement Credit Eligibility
   If the unit cannot be repaired under warranty, the first warranty incident may qualify for credit toward a replacement unit.
4. Remanufactured Unit Replacement
   Remanufactured units are eligible for one replacement during the ownership of the original vehicle (VIN-specific).

All warranty claims require the module to be returned to ACS for inspection and verification before coverage is approved.

Warranty does not cover failures caused by:

• vehicle wiring problems
• sensor failures
• alternator or charging system faults
• water, oil, or coolant contamination
• corrosion damage
• accident or fire damage
• impact or physical damage
• broken connectors or bent pins
• aftermarket performance modifications

These conditions originate outside the ECU and can damage any electronic module.

Unauthorized Repairs

Warranty becomes void if the module has been:

• opened after leaving ACS
• modified or altered
• repaired by another facility
• tampered with in any way

Electronic modules contain tamper indicators that allow technicians to detect unauthorized access.

If a warranty claim involves a second “Test Unit”, customers must provide a single continuous video recording clearly demonstrating:

1. Show the Original/Programmed ECU Operating in the Vehicle
   The video must clearly display the vehicle VIN on the scan tool or dashboard while the programmed unit is installed and the vehicle is functioning correctly.
2. Removal of the Programmed ECU
   Within the same continuous recording, show the complete removal of the working programmed unit from the vehicle.
3. Installation of the Rebuilt or Remanufactured ACS Unit
   Install the ACS rebuilt or remanufactured ECU in the vehicle during the same recording.
4. Demonstrate the Reported Issue
   After installation, clearly show the vehicle failing to operate or exhibiting the reported issue.
   

Important Requirements

• The entire process must be recorded in one continuous, unedited video.
• The VIN must be clearly visible during the portion where the original programmed ECU is shown working.
• Edited clips, multiple videos, or incomplete recordings cannot be accepted for verification purposes.
  

This process helps our technicians accurately confirm the reported issue and ensures fair, efficient handling of warranty or test-unit claims.  Warranty is voided by any of the following:

• Installation into a vehicle with unresolved root issues (e.g., shorted alternators, faulty grounds, or active TSBs). 
• Damage from improper installation, voltage spikes, corrosion, or water intrusion. 
• Any tuning, modification, or third-party tampering post-service. 
• Missing warranty labels or evidence of physical opening. 
• Any unpaid invoices or declined prorated repair charges.

Warranty coverage is limited to the module serviced by Auto Computer Specialist.

ACS is not responsible for:

• installation labor
• diagnostic labor
• towing charges
• rental vehicles
• vehicle downtime
• lost income or business interruption

Liability is limited to the repair, replacement, or original service cost of the module.

Warranty Eligibility

Warranty coverage applies only to:

• the original purchaser
• the original vehicle VIN associated with the service
• the original repaired module or supplied replacement

Warranty is not transferable if the vehicle is sold.
