Common Fixes We Handle with ECU Programming or Cloning

With ECU cloning, we fix a wide range of common problems that can leave your car stuck. A simple battery change can sometimes cause the ECU, PCM or BCM to lose sync, making the car refuse to start. Flood or water damage often means the ECU or BCM needs data transferred into a donor module. If the wrong or a used module has been installed, we reprogram it and write the correct VIN so it matches your car. We also handle immobilizer faults like “Immobilizer Active,” “Protection Active,” or “No Key Detected.” Failed tunes or flashes can be recovered where supported, and when a transmission is stuck after a TCU swap, we carry out the necessary coding and adaptations. For Mercedes models, we specialize in EIS and ESL modules, transferring data to restore proper key and steering lock function. Not sure it’s the ECU? Check our guide to bad ECU symptoms.

Brands and Platforms We Support

Our ECU, PCM, ECM, BCM programming and cloning services cover a broad spectrum of vehicles, from popular Asian imports like Toyota, Honda, Nissan, Subaru, and Hyundai/Kia, to advanced European systems found in BMW, Mercedes, Audi, and more. We also work with many domestic models, including GM, Ford, and later Chrysler, Dodge, Jeep, and RAM vehicles.

What to have ready before you call

The symptoms you’re seeing

Most customers get a donor module and we clone it. If you’re installing a brand-new module from the manufacturer, we have the OEM brand tools to program it and sync it to your vehicle. Not sure what you need? Call us at (808) 758-4599 and we’ll walk you through it.
