battery tender?

[HDSlicer1]

Hey all if i install a battery tender on my 08 nightrain when i disconnect the battery will i lose any info or the stage one download or is there like a separate battery that will backup the download? thanks

No info on the stage 1 download lost, that is a flash to the ECM to change the values.  Go ahead and hook up your battery tender.  Most scoots come from the dealer with the pigtail already installed so check before you attempt to put another one on.

Disconnect the battery any time you want,....  you will not lose your ECM info.
