About Auto Computer Specialist (ACS)

---

We perform full in-house bench testing using manufacturer-specific tools and advanced diagnostic software (this is part of ALL R&R Services). This allows us to identify communication issues, faulty components, or intermittent failures that typical scan tools can miss.  No guessing — real answers before you invest in repairs. 

Our R&R (Repair & Rebuild) service restores your original unit by replacing failed components, correcting corrupted data, and resolving communication or sensor-related issues. This service preserves your factory programming and eliminates the need for re-coding in most cases.

We offer fully remanufactured ECUs with updated components, pre-programmed to match your vehicle’s original specifications (when available).

• Ideal for units too damaged to repair or when fast turnaround is needed.
• VIN programming, key coding, and software updates available as needed.

Need to transfer data from a failed ECU to a donor unit? We clone the VIN, immobilizer, and software information so your replacement works plug-and-play. Perfect for vehicles where new ECUs are discontinued, unavailable, or prohibitively expensive.

Electrical shorts and worn wiring are often the root cause of ECU damage. We restore, repair, and replace critical harness sections to prevent repeat failures. Fix the real cause — not just the symptom. Ask about full harness rebuilds.

We provide tailored solutions for shops, fleets, and auto recyclers — with discounted pricing, priority turnaround, and dedicated support for high-volume clients. Join our Elite Program for exclusive member benefits and service priority.
