Change USB and Cigarette POWER TIME after ignition is OFF

[GrabThatBlue]

I might have found a very important setting for some people who are interested.

We all knew that the USB port, especially the one that we use behind the rear view mirror for the dashcam stays on for longer than 1 hour.
Some said 1 hour, some said 1 hour and 20 minutes and some said 1.5 hours.

I was interested in a dashcam, but the fact that it will stay on for 1.5 hours after the ignition is off, is not something I would like for my car battery.
A dashcam would be only installed in my car if I can lower the timer, and I think I found the setting to lower or higher the timer.

I came across this setting because today I took the time to compare the EU Mustang with the NA Mustang, 1 by 1, and I'm still not finished yet.
I'm creating a spreadsheet with all the differences and this is also a difference.

The European Mustang has the timer set for 30 minutes while my Canadian Mustang is set to 1 hour and 15 minutes.

This is how you can change it:

BCM 726-57-01: **** xxxx xx--
30 minutes = 0708
1 hour and 15 minutes = 1194

Here is the calculation for both numbers:

Hexadecimal 1194 to decimal:
119416=(1×163)+(1×162)+(9×161)+(4×160)1194_{16} = (1 \times 16^3) + (1 \times 16^2) + (9 \times 16^1) + (4 \times 16^0)119416=(1×163)+(1×162)+(9×161)+(4×160) =(1×4096)+(1×256)+(9×16)+(4×1)= (1 \times 4096) + (1 \times 256) + (9 \times 16) + (4 \times 1)=(1×4096)+(1×256)+(9×16)+(4×1) =4096+256+144+4= 4096 + 256 + 144 + 4=4096+256+144+4 =4500= 4500=4500
Hex 1194 = Decimal 4500
4500 seconds = 75 minutes = 1 hour and 15 minutes


hexadecimal 0708 to decimal.
070816=(0×163)+(7×162)+(0×161)+(8×160)0708_{16} = (0 \times 16^3) + (7 \times 16^2) + (0 \times 16^1) + (8 \times 16^0)070816=(0×163)+(7×162)+(0×161)+(8×160) =(0)+(7×256)+(0)+(8×1)= (0) + (7 \times 256) + (0) + (8 \times 1)=(0)+(7×256)+(0)+(8×1) =0+1792+0+8= 0 + 1792 + 0 + 8=0+1792+0+8 =1800= 1800=1800
Hex 0708 = Decimal 1800
1800 seconds = 30 minutes

So again:
If you want to change the timer to 30 minutes, use 0708
If you want to change the timer to 75 minutes, use 1194
If you want to change the timer to some other length, use this calculation: Seconds = Hex2Dec(****)
This is the Max Range: 1 - 64800

The Australian ALM5.0 guy did a real life test in his Mustang and it turned off at 1 hour and 19 minutes (real life timer).

I live in Canada I have my camera plugged into the mirror USB port. With my radar detector plugged into the cigarette lighter port. I never turn them off because the car seems to go to sleep in about 30 minutes after I leave the car. This setup works great and does not cause any heavy battery power loss.

30 minutes is acceptable.

I've wired my detector to the plug in the camera housing, so that powers on/off with ignition.
I have my detector phone and dashcam powered through the lighter port and I just rely on car power off if I forget to pull the plug. Seems to work fine so far, no battery issues. Current draw would be very low in any case.

I understand that people don't have issues with the battery. It's not that.
What is not now, can be tomorrow.

I'm saying that I don't want to put too much on the battery, so if there is an option to lower the timer, that's the way to go for me.

Just like the Welcome Lights. I turned it off, because I don't want to have unnessary battery usage.
Having the timer for 1 hour and 15 minutes after ignition is off is just too and unnessary much for me.

Fair enough.
If I didn't use the car almost daily I'd wire a connector for my battery maintainer and use that to keep the battery healthy, and make sure there's no extra draw.
My bike battery was still working fine using that system when I sold it after 9 years.

Unfortunately I don't have any power in the garage for a battery tender. I'm going to move to Europe where the weather is dropping way below freezing point. Batteries die there all the time. No need for battery eating devices after the car is turned off.
