Just wondering what you guys use to keep your battery goin while the tune is downloading...

 

If you're battery isn't keeping up with your tuner, then you have some serious problems. The tuner probably draws not much more than your dome light. You should be able to swap tunes all day without putting a dent in a healthy battery.

 

I never had any issues with my battery, when uploading my custom tunes. I would suggest taking your battery to an automotive store and have it tested. You may need to replace it out.

 

Lol unless you are using a diablo? I heard those take pretty long... Still don't think it is long enough to kill your battery.

 

i haven't tried yet...haven't even got my CAI and tuner lol...i was just asking, because i didn't know how much juice it takes from the battery, because i could have swore i saw a video somehwere of somebody loading tunes and recommending something to keep the battery goin...just thought i'd ask before i went out and bought something lol

thanks guys

 

Yeah I mean you're talking 10 minutes max of pull from the tuner, and of course it shouldn't use hardly any wattage while it's running.

Nothing to worry about!

 

The concern is that if the tuner is interrupted, it could get ugly such that it could corrupt a file or screw up the PCM; I'm not really sure. The recommendations that I've seen written is that you ensure you have all the accessories turned off (i.e. radio, fan, etc.) to prevent the battery from dropping below whatever minimum voltage the handheld is designed to work at. IMO, it's just a precaution in the VERY UNLIKELY event your battery is weak to begin with. Other than that, I wouldn't give the battery a second thought. I've changed tunes on the side of the road many times and never worried about it.

 

LOL.......so I am not the ONLY one!!!!!!

 

so fan off, radio off, lights off(obviously lol) and i'm good to go...sounds good

 

The video you saw, they might have been taking precautions to the extreme tee or just paranoid. Like Nuke said, if your battery can't keep up with the tune downloading, you're having serious issues. I wouldn't sweat it otherwise.
