Losing Tune W/New Battery?

[The Demon]

I apologize if this has been asked before as I couldn’t find anything. I don’t know exactly when my battery is going to go out but sometimes even in California with warm weather the car takes quite a few cranks to start. I’m pretty sure I might be on my last year with it. When you change out the battery will I lose anything with my Lund tune from the NGauge or will the car remember it? Just asking so I know what I need to be prepared for. Thanks for any feedback.

You won't lose your tune. Its hard written. Now the learned tables yes you could lose those but thats no biggie they will quickly relearn.

Awesome. Thanks for the clarification. I wasn’t sure how that stuff worked.

I put a battery tender on my car because i was having same issue with starting the car.

You can put a jumper box on the car while you change battery’s to prevent it from loosing any data it has gathered
