ECM Cloning & Repair in Chicago

Tachyon Auto Service offers ECM cloning and repair services. If you suspect an engine control module problem or are considering a replacement, contact us to discuss your vehicle and available options.


Service suitability depends on the module, its condition, and compatibility with the vehicle.

What Is ECM Cloning?


For supported applications, cloning involves transferring relevant data from an original module to a compatible replacement.


Cloning is not possible in every case. The condition of the original module and the compatibility of the replacement affect whether the required information can be transferred.

Confirm the Fault Before Replacing the ECM


Starting problems, communication faults, and warning lights do not automatically mean the ECM has failed. Wiring, power supply, ground connections, and other vehicle systems can produce similar symptoms.


Diagnosis helps determine whether module repair, cloning, programming, or another repair is appropriate.

To help us assess the request, provide:


  • Vehicle year, make, and model.
  • The symptoms and any diagnostic codes.
  • Original module part number.
