How do you keep ignition on for long period?

[Tbonem3]

I'm pretty sure you need the ignition on the entire time you're flashing. For let's say a 45 minute flash - how do you keep the ignition from turning itself off?

I read someone say buckle the driver's seat belt, but that didn't work for me, the system still turned itself off after a few minutes.

Someone else said if you have a battery charger on, the system will know and won't time out, but I tested it with a 50amp charger and it still timed out.

I'm hoping the car knows not to time out if its in the middle of being flashed?

Any other tips?

keep drivers door open

What do you mean it "still timed out?"

Edit, forgot I was in the E9x subforum, not E46. Are you putting the key in the key holder or are you trying to use it via the Comfort Access feature?

The door's always open, that doesn't stop it from timing out at all :/

Tell me about it. Everytime I work on teh e9x, I miss the E46. Just turn the key and leave it.

No, I've got the fob in there because that does seem to keep it on longer, but it still times out.

Plenty of people flash their e9x, and those flashes, a lot of the time, must be longer than 5 min or whatever the period of time is, so I'm hoping the car knows to leave it on if it's being flashed.

I've never had the car turn off when I program/code an E9x so this is an interesting one to me. I always have a charger hooked up and the LF door open BUT latched so the car things its closed).

What program are you using and what module(s)?

I just flashed my dct with the updated U.S. file (..869) with Winkfp and it only took like 7 minutes. The power did not turn off (I have a battery charge on, door was open, key fob in).

While playing around in Expert, the ignition did time out, but all I had to do when I wanted to FA write, was press the start button once (with foot OFF brake), and it came alive, and I executed the write job (VO update for disabling TPMS and adding in FTM).

I'm more worried about flashing to the engine ECU, like a modified bin where it might take 40 minutes.

Power supply hooked up, driver's door open, double click the engine start button without pressing clutch (manual) or brake (dct) and carry on. Never had an issue. I'm no expert, maybe the software keeps the car awake.

It's not flashing software, it's drivers door open which keeps ignition on.
if door is closed locked or not CAS will shut off hardly the car to save battery.

So if the driver's door is closed, it'll automatically shut off even if it's in the middle of a flash?

Maybe if you are using aftermarket software, but definitely not if using factory software.

Thanks, I'll test that.

I still think it's probably true that the car knows when it's being flashed.

I just flashed my mss60 with new factory software, took about 10 minutes, ad the ignition didn't turn off. Door was open. No seatbelt buckled tho.

Seatbelt buckled is needed for F8x

and no the car will shut down if you flash and ckose the door and time out is gone.
CAS doesn't know anything about MSS60 flashing, because power can is down

But don't worry if happened. Start flash procedure new and flashing starts from the beginning

No possibility of bricking if this happens?

[ppm008]

No, if your flashingtool is winkfpt:
bricking could only happen by flashing nonsuitable data according to the prog in expert mode.
So check corresponding of data and prog before flashing
