Mobile in DFW - mail-in available nationwide. Most quotes are returned in under 4 business hours.
A new ECU ships virgin - no VIN, no calibration, no adaptation data. A donor ECU comes locked to a different vehicle. The work that turns either one into a running engine on your build is OEM-grade software, bench programming hardware, and the patience to do the full sequence every time.
Request nationwide mail-in bench service, or book a mobile visit if you're in the DFW metro. Our workmanship warranty covers defects in our completed work.
We bring OEM software and programming equipment to your DFW location. Any required vehicle checks or road procedures are confirmed with you.
Submit the request for review. If accepted, Core Auto Logic sends the final quote and packing and shipping instructions.

We use the VIN, repair details, and equipped systems to choose the access path and service workflow before the job starts.
Some control modules require direct bench or boot access so immobilizer, VIN, coding, and calibration data can be transferred from the original unit to a donor.
Send the original module, donor module, VIN, and a short fault history. Include water, fire, or no-communication symptoms.
Boot-mode service is used when normal communication is unavailable or when protected memory must be read directly before a replacement module is prepared.
Do not open the case before shipment unless instructed. Package the module dry and include any scan report or no-start notes.
When a vehicle-side path is supported, coding or adaptation can sometimes be completed without opening the module. Bench validation still determines the final workflow.
Provide the vehicle year, make, model, VIN, donor source, and whether the original unit still communicates.
Platforms used for module programming, calibration flashing, cloning, VIN write, and post-flash verification.
Symptoms that point to an ECU that needs programming, cloning or recovery. Programming is one possible cause; diagnosis must also consider power, wiring, hardware and vehicle conditions.
