Pretty sure the ECU does not need to be retaught as I had just done that a few days prior and I can see the pulse width numbers on the data terminal and they all look logical. Around 1000ms for shutdown, 1200 or 1300 for stick low and trim high (normal idle) and 1900or so for full throttle, but I will recheck them just incase. There was no smoke, our weather was approx 65 degrees that day and the humidity was quite low. I would hope the ECU would have a different message if this was the cause.
