Does CG FC200 support checksums? Many customers often ask themselves this question before purchasing a device. In fact, Auto ECU Programmer FC200 has its own data validation that is automatically calculated by the software. The checksum can only be used in the PFlashdata area. As long as we changed the PFlash data area, including but not limited to: error code shielding, anti-theft, performance upgrade and other operations. When loading and writing, the software automatically recognizes the data and helps recalculate the checksum.
During checksum, it is usually accompanied by data correction. This is a normal phenomenon. Just click ‘Yes’, and the software will automatically correct the written file.
In short, when writing the modified PFlash data area, the software will pop up whether to check or correct, we can click Yes, otherwise the vehicle can’t start.
Note: Data verification and correction requires the PC to be connected to the Internet.
