I have a SCT X4 programmer mounted to my dash with IAC, charge temp, rpm and spark gap displayed on it. It worked fine for a while, every time i would turn off the car and turn it back on the display would boot up automatically without me having to touch anything. Today i went into my garage to crank my car up and it wouldn't start (alternator went out, separate issue i think). I jumped it off and now my handheld isn't showing the display that it used to. Its as if i have a new programmer that doesn't know my car. If my battery dies, do i lose my custom tune i received at the dyno and have to start from scratch? Any help would be appreciated.
*I know im supposed to have my car off and follow the instructions on the screen but ive never had to do that before until now.
