Should I set my Smarty back to stock before replacing my batts or will it be safe to leave it on SW3? I've read that disconnecting the batteries can reset the ECM so I don't want to mess anything up.

Also, will my tire settings change after changing the batts?

Thanks!

 

I have disconnected my batteries a few times, no problems.

 

No worries.

 

Thanks! Have a very Merry Christmas!

 

glad i caught this thread.....good info and good question.......thanks to all
