@rokkuchan , it seems your PSU wasn't up to the task. The battery should have very little drain when connected to a PSU, if not what's the point.
Did you check at all times that your PSU had stable voltage around 13.6V? And that it's capable of supplying well over 20-30A at that stable voltage? You can learn much more in one of the older DIY PSU thread that I contributed to. |

Update:
My previous posting of current readings are wrong! The culprit is the fuse on the red alligator clip. I opened it up and the damn fuse was only rated 20A and some reason causing a bit of resistance too! Where I got it from says it's rated 120A - probably the cable/clips not the fuse. So I decided to cut it off as the PSU has protection anyway and now the reading is easily over 20A just putting the car in ignition with lamps on. It was only reading around 5-8A with ignition on before. So please ignore my amp readings previously. It's why my battery was drained. Picture attached with just car ignition on with radio, vent and lights on. Easily over 20A.... If ur building PSU perhaps don't use those in-line fuses. |

Sorry if this is off topic.
I have a 2015 F82 M4 and it's still on it's original software (dated Nov. 2014) and I want to get it updated. However I like the way the car tries to kill me when I floor the throttle and i've read the later DME updates kill the low down torque. So after I have the car fully updated, is it possible to downgrade the SW on the engine DME back to pre 2016 software ? If so, what is the latest software version before they killed all the fun ? |

I apologize in advance if this is the wrong place to ask but this is one of the more comprehensive posts about flashing BMW ECUs. Can anyone link me to a copy of full PSdZ data pre Feb 2017? I want to update my FEM_BODY (to get heated steering wheel indication in kombi) but retain the option to change the number of turn signal blinks. I only have 4.19.30.
Or if someone could give me the version number or i-step level I can try searching myself. The latest i-step number I've found that that is still pre Feb 2017 is F020-16-11-503 but I don't know how that translates into the psdzdata version number. Thank you! |

Are there any particular requirements when using another (running) car as a PSU? Would most modern cars be up to the challenge? Or do you need a particularly strong alternator?

No. Any car should work.

Well, the flashing itself was fine but since then my one-touch window opening and closing hasn't worked. I've tried everything but cannot seem to initialize them. They still move automatically when opening and closing the door though. |

I bricked one of them I can't remember which but no response from car at all. Water pump stuck on and can't even open boot haha. Esys stuck says requires xx hours to go. If you ever stuck in that situation don't despair. Just kill the window start again. As long as u don't brick Fem gw, you can always connect to it via gateway and force a reflash on the one that u bricked. I did update on gw last and that just took 1-2min I recall. |

For reasons I won't get into, I was trying to get my ECUs (2016 F80) flashed to a more recent I-Step (from shipment F020_15_07_506 to F020_20_07_530)
This was my first time flashing, so I started slow. I flashed one module, it worked fine. So I proceded to flash a second module (FEM_GW) as I understood it was responsible for communication to many other modules. That went fine as well. Then, I ran it again and flashed all the modules. This worked fine for all but two, HU_NBT2 and KOMBI came back with errors. Afterwards, the HU_NBT2 and KOMBI modules showed a ton of red/blue entries during the tal calculation (including the bootloaders). Further attempts to flash HU_NBT2/Kombi failed. Currently, the idrive display shows a blue screen that reads "Flashing Time: 00:00:00". I've gotten it to take a new bootlader (now shows black in e-sys) by flashing it via UDS (took hours). But trying to do the same for the SWFL failed after about 15 hours / 44% of the first file. The dashboard shows the blue high-beams light flashing, and nothing else. I've not really tried much to flash that, as it depends on HU_NBT2 as I understand it. Anyways, I know this isn't a lot of info to go on, but I'm happy to provide whatever would be helpful to anyone willing to try and help me out. I've been trying to flash with e-sys 3.33.4 (as well as 3.27.1 and 3.30.1, in case there were issues) using an ENET cable. I'm currently connected through a network with DHCP server (I was originally connected using the APIPA addresses directly to my laptop, and then later with a locally running DHCP server on my laptop). Currently, it's attempting a swDeploy to HU_NBT2, with messages as the following: (though the in-car display shows that it is making (slow) progress: [HU_NBT2 - 63 - swfl_0000271a-001_056_001] Transaction type: swDeploy; Message: 0% progress on ECUId:HU_NBT2_0x63 [0% of swfl_0000271a-001_056_001] [TRANSACTION] [EDIT:] Currently shows 62% progress, after about 55 hours. It's going, but very slowly. [HU_NBT2 - 63 - swfl_00002727-001_056_001] Transaction type: swDeploy; Message: 62% progress on ECUId:HU_NBT2_0x63 [0% of swfl_00002727-001_056_001] [TRANSACTION] I'm hopeful that if this does finish, I can get the HU_NBT2 back up and working properly, and then the KOMBI module will be flashable again. I suppose I'll keep updating, if for no other reason than to help the next poor fool who gets stuck in the situation I am in. Any help is appreciated, and like I said, happy to share whatever source is necessary, thanks in advance! Last edited by sctyboy; 09-13-2020 at 11:26 AM.. Reason: update |
