(100%) E9X M3 241E DME Flash (DIY)

jp1984 · 07-21-2022, 03:32 PM

Before everyone jumps to 241E, know that 240E is the preferable tune file.

I believe I read somewhere that 241E was worse due to some emissions changes. I am not sure exactly, however 240E with the MSS60 adaptations the car does with mods will bring you close to some tuners and it is from BMW.

Do you know what is changed?

How bad is 241E? Maybe it doesn't make max power, but it's not detrimental to the car right?

Where you are getting this info from? As far as i know its just operating system changes no ignition or fuel adjustment. 240E and 241E is identical in performance unless you have a valid info. You can also ask this to tuners like alex@alpine .

I have tried to contact Alex before, my impression was that he didnt have time to talk unless you were a customer.

I was curious why some tunes on his website mention safety settings in the disclaimer and the E92 M3 one lacks that information. Check it out.

Other tunes mention :

"Factory safety parameters and diagnostics systems all intact with fuel sensing adaptions."

https://alpinemss.com/products/e9x-m...tune-2007-2013

https://alpinemss.com/collections/bm...3-m4-2014-2020

The E92 disclaimer lacks that. I wanted to be sure I knew what I was buying but couldn't get an answer. I would love to buy the tune, but I have yet to get a clear answer on that.

Well i dont tune my dmes. I am a satisfied client of bmw original updates. And i can tell you that i am on 241E for more than 2 years and car is running great. I am catless with 300 Gesi HFC and i dont believe 240E better than 241E in performance!

You're looking too much into it. Each tuner has their own opinion, approach, and base software version they start from. Pick a tuner you're comfortable with and go to town. Or better yet, save your money since the 15hp isn't worth it. FWIW, I ran a tune for a couple of years prior to adding a blower to my car. Couldn't say I felt a difference with it, but I bought one because the price was right. in hindsight, I would have saved the $500 or whatever it was I paid.

If you're catless and looking to kill the CEL, there are other options out there that are more economical.

SaNGRia is absolutely correct.

The change from 240E to 241E reflects only a change in the program file (from 7848125.0pa to 7854317.0pa). All of the parameter files (*.0da), the ones specifying values for ignition, injection, VANOS etc, are the same.

Probably TLDR but this is easy to verify by inspecting the datens - the parameter file names are the same in "240" datens like v53.3 and "241E" datens like v60.1. Furthermore, all of BMW program and parameter files are in BINHEX format, meaning you can read them with a text editor like Notepad and they include text notes in addition to code. In fact, the $REFERENZ numbers written in those parameter files include "240E" - there was no updating of the parameter files beyond 240E.

As I specified earlier in this thread, the calibration/data area is nearly identical going back a decade. The changes are almost always to the program area only. The only reason why this uses the same 0da is because the version string itself did not change, so the checksum/signature blocks for the data area are identical. Many previous data areas are also 100%, other than the reference number, which would call for a different data area ZB, although the mapping is the same.

Hi mike,

just for the benefit of the audience, would you mind sharing why you think 240E is preferable? I saw you mention it to deansbimmer in another thread.

Doing the 241E & GTS DCT flash today. First time attempting to do something like this on E9x platform - wish me luck!

Good luck

chicagob5 · 09-02-2022, 01:51 PM

Circling back on this - finally got the bimmergeeks pro cable. Before flashing I wanted to test the connection was solid using INPA. Initially had issues getting INPA to detect the cable despite the usual issues being correct - COMM1, Latency = 1 etc.

Turns out the default windows drivers for the cable where the problem. Using drivers from https://ftdichip.com/drivers/ fixed my problems.

Turns out the car is running 241E so thats cool. I did flash the transmission module with the 7848442 file for the GTS DCT tune. Worked great. Highly recommend!

Thanks to everyone who contributed to this thread to make this possible for folks like me. Obviously big shout out to SaNGRia for the initial writeup - you a real one :fistbump:

Binary420 · 11-05-2022, 11:31 PM

so i used mss6x flasher to take a full backup , flash the rsa bypass, and then remove the 1 byte to disable immo.

I then flashed this modified full backup back to the dme

all went well, but sadly, it didnt fix my start issue. engine still just cranked but wouldnt start.

So after exhausting my other options, i attempted a update with winkfp to wipe the mss6x flash, thinking maybe that was now an additional issue causeing car not to start.
update got to 100% and then stopped with an error

now my MSS60 ECU is not responsive.
i tried with ident with tool32, tried inpa, winkfp,

is there a certain specific command im suppose to be giving in tool32, or is there any other option to re-flash the dme? or im fked?

I've used the wrong cable and therefore the update failed. DME shows red/unresponsive in ISTA. Car cranks but no start. If I get the correct cable, will I be able to rectify if myself/remotely or must the ECU be sent to somebody. I'm in Australia so that's why sending it will be a problem.

Thanks in advance.

Thank you.

I've ordered the cable from Bimmergeeks about two weeks ago, should hopefully get it in the next few weeks.

I'm trying to get my post count up so I can pm when I get it but are you able to pm me a way to contact you if possible? Appreciate the help you're providing.

I will send PM too if that is ok. Trying to help a friend do an update, i have now bricked his DME by using the cheap cable. I do have bimmergeeks and icom, but i generally use the cheap one with no issues. Any help would be appreciated. Will send PM

cheezeit · 07-07-2024, 05:57 PM

Thank you for these instructions! I was able to flash to 241E successfully. A few tips for anyone else attempting this in the future:

A cheaper and available cable that can do this flash is the Bimmer Tuning Tools K+DCAN cable ($39). When I was looking the $50 Bimmergeeks Pro cable was out of stock indefinitely and the more expensive Bimmergeeks expert is pretty much the same thing. These cables don't have any special hardware in them - they are the same cheap generic K+DCAN cable but flashed with patched firmware that fixes a bit corruption glitch and also runs at a faster speed. If you like tinkering you can even flash the patched firmware yourself with an arduino.

With these updated cables the flash only takes 10 minutes or less. If you have a healthy battery that has been charged recently you can do it without a power supply backup (that's how I did mine). From what I've read the flashing process is designed to be robust - even if power was lost in the middle, the flash is recoverable - just start the process over when power is restored.

You can use INPA to check what your current DME version is and compare against the dates in this post: (https://www.m3post.com/forums/showthread.php?t=797020)
You can check for your I-step Plant (what the car shipped with), Dealer (what the dealer flashed if it got updated at some point), and Backup.

You can also check the MSS60 identification pages for a field named "DIF Injection" or "Programm-Stand". Mine was 0569QT0Z130EEKUV0 for example, the 130E in the end is my DME version (130E or 100E).

I would add the following steps to the original instructions if you haven't run WinKFP before (or some of the buttons won't show up):

Steps :

1- Hook up the Battery Charger
2- Connect the OBD cable to car and PC
3- Buckle Up Driver seat belt
4- Roll Down the Driver Window
5- Close the Door
6- Turn on the ignition (Do not Start the Car)
7- Open the Winkfp
8- Select Comfort Mode
9- Select Update ECU
10- Select Module (MSS60)
11- Write your 17 Digit Vin. << This button won't be there if you haven't configured WinKFP yet. Go to WinKFP configuration settings and check "UIF write in comfort mode", then re-start WinKFP and redo the steps.
11B- Select Done (or it won't proceed)
12- Select Prog ZUSB
13- Click Ok on the Pop Up screen (Which says The Users info field can still be programmed 62 times)
13- It will go 0-100 fast at the first stage than will start Flashing. (About 10 min)
14- Then another screen will pop up saying the same thing (The Users info field can still be programmed 62 times) Click OK again
15- It will take about 30 second to do another 0-100
16- ZUSB-Update programming OK message appears
17- Fuel Pump will be activated and you will have some errors stored in the ECUs. Mine is MT so i only got DSC Malfunction on iDrive and Cruise Control Symbol with Exclamation Mark on the KOMBI. After clearing the ECU Errors either with INPA or ISTA, should be all set.

Do NOT attempt with regular DCAN cable if you do not want to fail on DME Update.

I also found these youtube videos helpful for updating DATEN and importing DATEN into WinKFP:

dommer · 08-08-2024, 08:25 PM

Would anyone be willing to help me get the software installed? I'd pay for your time. I downloaded something from Mega, but it's 100% in German and I read 0% of German.

machiuu · 05-19-2025, 07:36 PM

Has anyone been able to modify the tables to code out the Secondary Air Pump? I have bimmer protools and was wondering if anyone could point me in the right direction? Valves went bad so i might as well plug and delete SAP.

shifted.m3 · 05-21-2025, 08:31 AM

Hate to hijack and revive this ancient piece of gold, but too much knowledge here not to try my luck.
Would you guys expect success following this guide with an EcuWorx cable, and attempt to flash back to stock 240e software from a read locked DME due to ESS software?
And how do you guys pick the right ZB number / correct Daten files to import?
Any insights would be appreciated..
