Winter Storage Battery Question

[BaileytheDog]

I will be storing my car off site this winter (Wisconsin). If I remove the battery for the winter, will all the computer modules lose their "learned" settings? I'm assuming anything I changed with ForScan might go back to stock.
For security reasons, I might just take the battery out. But if I do not, could I just pull the fuel pump fuse or something like that to make it harder to steal? I don't thing I'll have any issues as I stored my old 1970 in the same location and those are a lot easier to grab. But just as an extra precaution.
Lastly, it is a unheated space. Would you pull the battery and put it somewhere warm, or trickle charge it? I know this is personal preference, just curious on what people think.

Yes, it will lose all it's learned calibrations.

No, it will not change Forscan settings.

Yes, you could pull the fuel pump, but really taking the battery out will be enough.

Yes, keep the battery warm and on a battery tender.

Don't you have Ford Pass that will alert you if the alarm is triggered? Maybe that's the better idea. Leave the battery installed and on a tender, so you get alarm alerts.

I do have Ford Pass, but I'm over 2 hours away.
It is easy enough to pull the battery, I just was not sure how much it would affect the control modules and if it really matters?

I have always pulled my battery and brought it inside.. cars and bikes.. not once have I had an issue when starting the car/bike back up during spring time.

I'm not so sure it will lose learned calibrations either. I was very surprised to see that my 2020 maintained all DTC and emissions monitor data after sitting with a dead battery for several days. Historically on just about any other older car, that info is completely gone instantly when the battery dies and/or is removed.

I was referring to "learned" adaptive powertrain information.

Understood, but if Ford has enabled the PCM to store the emissions test data and DTC's in the event of a power failure, storing the adaptives in the same manner would only seem logical.

And yet, they don't.

Hence, how many times people are told to disconnect their battery for a few minutes to reset adaptive learning stuff like transmission logic.

I agree, it’s no different than disconnecting your battery when working on the car.

OP, you’ll probably lose your active exhaust quiet mode settings (if equipped and you use it) and maybe your stereo presets but the car will save all the vital/necessary learnings.

Do you know that for a fact, or are we basing the assumption off of something that may have worked on older cars? How many times have you seen people say to disconnect the battery to clear a DTC, and yet it doesn't seem to work on my 2020. Technology changes.

You're changing the topic. We're not talking about DTCs. Never were, not now. And I've never seen anyone suggest disconnecting the battery to clear a DTC. The suggestion is always a scanning/tuning tool to clear DTCs.

Based on hundreds of posts right here on this forum about resetting adaptive learning stuff by disconnecting the battery, I'd say it's a fact.

I've never seen a Ford WSM state that disconnecting a battery is an acceptable method for resetting adaptives, but because you saw it in some forum posts it must hold true for all model years? Again... technology changes.

Leave the battery in the car on a tender. If you remove it how will you know if it was stolen or fvcked with? Phone is only a minute call to police. Or drive two hours to find an empty space where you once had a Mustang.
It may be in a shipping container by the time you find out it is gone and on the way to a new owner in Europe.

+1 on the battery maintainer. I use one on my intermittently driven 2017 and it still on the factory battery.

Now you have done it. You will need a new batt in the spring.
