Caption:

• RD: Read
• WR: Write
• CK: Checksum correction

Supported ECU

• 2.7L, 3.3L, 3.8L (MT38/CAN) [WR/CK]
• 2.7L, 3.3L (MT38/K-Line) [RD/WR/CK]

Operating Features:

1. For all modules except BSL: In case of an interruption during writing, you need to turn off the ignition for 10 seconds (until the main relay turns off) or press the “Reset” button to return the ECU to a “normal” state. If an interruption occurs during writing, nothing critical happens; simply start the process again.
2. Reading:
   • MT38 K-Line, MT38 BSL: A full flash read (2048 KB)
   • MT86: Only calibration data is read (128 KB).
3. Writing:
   • 3a. MT38 K-Line, CAN: Software writing (without service areas); full-size files are supported, ChipLoader format files (missing the last 64 KB), and GDS format files.
   • 3b. MT86: Calibration data writing (with a warning message), if present in the file (128 KB/1504 KB), or firmware in GDS format or full flash files.
   • 3c. MT38 BSL: If a full-size file is written, the entire flash will be written, including service areas (EEPROM, boot). If the file is in GDS or ChipLoader format, only the software area is written (without service areas). To write only the software area using a full-size file, hold down Shift and press the “Write” button.
