I have a quick question, what is the * on the OEM piper temp gauge ? I cannot seem to find any information as to what this means.

Can anyone explain what that means to me? I have noticed that when I lean to rough and enrichen slightly, I am very near this temp. good/bad I have no idea.

I am considering removing the OEM temp gauge for a JPI engine monitor, but have not proven to myself I understand my factory equipment enough to know why I should upgrade.

Thanks in advance
