My battery went totally dead and I had to jump start her. I have it stored for winter and have been starting it every 2 or 3 weeks with no problems, until today. It has been much colder the past couple weeks - I don't know if that is what killed it?? Does anyone know if that will erase my 93 octane tune?????

 

I don't see how it could. Otherwise, the factory tune would be lost if the battery died.

 

I thought it might default back to factory settings.

 

Isn't it flash memory? Battery power wouldn't matter then.
