Is it true that I can disconnect my battery and not worry about any codes?? I have an 05. Hate to pull the plug and come to find trouble in the spring. No mention of this in my search or my 996 companion. Thanks Matt

 

i dont know, i use a battery maintainer, i think the majority of people do this

 

I also use a battery maintainer, but if you must disconnect the battery, I don't see why not.

 

There is no problem to disconnect it....

 

The only thing you will lose is the learned function of the ECU (which will relearn) and the clock will need to be reset...LOL

 

Your PCM/radio/nav system might need an unlock code. My LCD had gone out, and once I had to replace the battery, I could no longer use the radio. The LCD was prompting for the radio unlock codes.
The rest of the car can be unplugged just fine.

 

I had the radio unlock code before?

 

I bought a Porsche trickle charger that plugs into the lighter socket. Works fine.

 

Battery Tender

 

As others have said, battery tender. There's a 50/50 chance you may have to reset your windows too, if you have one touch up and down. No biggie, takes 5 seconds.

 

I'll ask a totally different question. Why park it? I bought mine, selling my Corvette, specifically so I can drive it year around. Best snow car I have ever owned.

It's a car. Drive it. Every day

 

You might want to put some Stabil in a fresh tank of gas before you stop driving it. Keeps the gas from spoiling and turning to varnish. I do that in winter even though I drive it occasionally on a nice day to circulate the fluids.

 

Good advice regarding the Stabil and warming it up occasionally.

Just to put my all-time idiotic question to rest, there is no harm to an aftermarket tune from disconnecting the battery since the tune is effectively "written" to the ECU and that is all the car knows, correct? I assume this to be true, but it's also my first vehicle that has an ECU that can be over-written directly (and is tuned). My previous vehicles either had stock ECUs or were intercepted by piggy back devices, so none of this was ever a concern.

I assume we'd hear about this problem all of the time if something as simple as changing the battery would cause problems for the tune. I plan to disconnect my battery in the near future for a steering wheel swap so it has been on my mind. Also worth noting is that I purchased the car with a tune so have no direct recourse with a tuner to flash it again.

 

I have never heard of that being a problem. I disconnected my battery for a few days this past spring to remove my steering wheel for a re-cover, and had no problems with my tune once the battery was re-connected.

much to nice a car to subject to the salty roads of a Michigan winter. I've got a c4 for that purpose. Thanks for the replies.
