The yellow beast is heading to Norway to a new home. It has been a great project and I appreciate everyone's advice and encouragement. The final tune on the Megasquirt setup is complete and I wanted to share the configuration settings with the community. Remember, each Megasquirt is a little different, but this may be helpful for folks trying to get a good start.

Best wishes and many thanks to you all.
