Tool
Holley EFI Parser
Holley EFI Parser decodes Holley DL and DLZ data logs and live ECU CAN messages. Its Python tools decompress DLZ with byte swapping and RLE, parse versioned DL records into pandas DataFrames, and decode CAN messages using supplied DBC files. The documentation records the proprietary 29-bit CAN identifier layout.
