Auto Computer Specialist (ACS)

---

Due to the specialized and non-reversible nature of our work, ACS does not offer refunds once service has begun. Our technicians allocate time, software licenses, and parts immediately upon receiving your unit. This policy ensures fairness and helps us maintain the high standards our customers expect. 

The following services are strictly non-refundable:

1. Repair and Rebuild Services: We base our service on your provided DTCs and vehicle symptoms. ACS does not perform vehicle diagnostics.
2. Programming Services: Once software or calibration has been applied to a module, the process is permanent and cannot be undone.
3. Testing Services: Even when no fault is found, the technician’s time and tools are utilized, making testing non-refundable.
4. Cloning & Data Transfer: These services are unique per unit and cannot be reversed.
5. Shipping & Handling: Shipping costs are considered a completed service once the item is scanned by the carrier.
6. Tampered Units: Refunds are not issued for any ECU that has been opened, altered, or damaged after return.

Returns are accepted only for Remanufactured Replacement Units, and only under the following conditions:

1. The return is initiated within 14 days of delivery. 
2. The unit is unused, uninstalled, and sealed (all warranty stickers intact). 
3. The unit has not been altered or energized in any way.
    

Returns that do not meet these requirements will be subject to a 60% restocking fee, which also applies to returns resulting from incorrect diagnosis or customer error.

Please note that ACS products may not be used for trial-and-error diagnosis. Installing a unit to “see if it works” without verified ECU failure or root cause correction violates our policy. Such returns will be denied or restocked at partial value.

To ensure accurate service and timely turnaround, all customers are required to:

1. Submit a complete vehicle scan with all DTCs relevant to the issue. 
2. Complete the official ACS Service Form and include it in the shipment. 
3. Remove any aftermarket tunes or flash software prior to submission.
    

ACS is not responsible for the loss of performance tunes or non-OEM software. We do not restore or preserve third-party calibration data during service.

Turnaround times begin once both the ECU and completed documentation are received. Approximate timelines are:

1. Repair / Rebuild (excluding A50/T14 units): 3–5 business days 
2. Remanufacturing: 3–5 business days 
3. Programming / Cloning: 1–5 business days 
4. Wire Harness Restoration: 10–15 business days
    

Delays may occur due to technician workload, parts availability, or unforeseen issues. Customers should plan for reasonable downtime and check tracking updates regularly.

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.

ACS offers a Limited Lifetime Warranty with Unlimited Mileage on qualifying Repair, Rebuild, and Remanufactured (Replacement) services performed on or after June 15, 2022. This warranty is exclusive to the original purchaser and is non-transferable. 

• Covers only the original work performed by ACS.
• Includes one in-warranty repair or service, provided the root cause has been addressed. 
• The first warranty incident may qualify for credit toward a replacement unit, if repair is not feasible.
• Remanufactured units are eligible for one replacement during the ownership of the original vehicle.
• All units must be returned to ACS for inspection before any warranty coverage can be applied.

Required Proof for “Test Unit” Claims If a claim is based on a non-functioning replacement, you must submit a single continuous video that clearly shows:

• The original ECU working (with visible VIN),
• The installation of the ACS-supplied ECU,
• The failed behavior of the ACS unit post-installation.

Without this footage, your warranty claim may be denied.

 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.
