Reading Hyundai Delphi DCM7.1AP ECU with CG FC200 and DAP Adapter

Update time : Jan 27, 2026 / Views : 462

Essential Tools for the Task

To successfully read the Hyundai Delphi DCM7.1AP ECU, ensure you have the following equipment ready:

CG FC200 automotive programmer
Latest version of the DAP adapter
Stable 12V external power source

DAP Adapter Connection Techniques

The DAP adapter is a versatile tool compatible with several ECU types, including Toyota first-gen DENSO units, Delphi DCM7.1AP and DCM7.24 chips, and PCR2.1 immobilizer data extraction. You can connect it to the FC200 programmer using two different approaches.

First Connection Method: Utilize the included female connector, attaching the male end to the FC200. This provides flexibility and spacing between the devices.

Both configurations are effective. This guide proceeds with the direct connection method for simplicity.

Software Configuration and Memory Reading Procedure

Launch the FC200 software on your computer. Select the appropriate option for Hyundai-Delphi DCM7.1AP (Hyundai TC2771) from the menu.

Successful connection confirmation on hardware

After activating boot mode and establishing a stable connection, initiate the EEPROM (also referred to as Dflash) reading process. The FC200 performs this read operation rapidly.

Save the extracted EEPROM data to a dedicated folder, such as "Hyundai," on your computer.

Proceed to read the P-Flash memory. The FC200 programmer showcases high-speed performance during this phase, demonstrating its reliability for Hyundai, VW group, and other vehicle ECUs.
