Important Notice

 

This software does not support virtual read files or modified dump formats generated by some tools.

 

Unsupported files include:

Corrupted, incomplete, or non-original dumps.

 

 

For successful decoding, a genuine PCR2.1 full flash read is required. Virtual read files generated by certain OBD protocols may not contain the complete ECU data structure needed for decryption and processing. PCR2.1 ECUs often use virtual read methods with some tools, meaning the resulting file is not always a true full dump.

Original PCR2.1 full flash dump.

 

File size up to 2.00 MB.

 

Read using a supported Bench, Boot, or Full Read method.

 

Unmodified binary file (.BIN).

 

 

Applications

 

ECU cloning.

 

IMMO data processing.
