Version 1.7.0.0 of the ECU flasher has been out for a few days now, and is definitely and improvement over the previous version. You can download it HERE.

What’s new in the latest version is:

• No longer blocks waiting to read message echo.
• No longer requires that message echo is an exact match.
• Now supports erasing and programming entire flash at once when sector erasing fails.
• Auto detects if the ECU is in sector erase or entire flash erase mode.
• Now supports recovering from previous failed flashing attempts.
• New generic 29F800 and 29F400 memory layouts that aren’t BB or BT specific.
• Lots of bug fixes to the communication system.

Also, to facilitate open development of B5 S4 tuning, I have released my base tune. You can download it HERE.
