I believe the procedures are already pretty well known, but good how -tos are missing. I learned checksums are coming to Tunerpro which helps having one inexpensive amateur software.

good how-tos are out there, you just have to be patient and keep on searching.

what you will NOT find is a how-to that shows you where you have to click and what numbers you should write. thats the know-how of people earning money.

^OK, you are right. There are how-tos. Somehow I still feel there are many variations. E.g: Many tuners prefer to go via OBD. Then, if you chooce to solder and direct EEPROM programming, like you, the directions are quite different. Also, many tools exist. Beginners, like me, get easily confused. Personally, I've decided to to play with the ECU in the car, but have the second ECU and play with in on my garage's table. Then, there is more room for trial and error.

with the effort from hakentt and tunerpro the most interesting maps are found. you just have to transfer their positions to your softwareversion and change the values.
with a bench setup and good hardware, you can easily see what each change does, so for using it

DME help

Hello guys.
Total Noob here. I am here with a much more pressing question regarding a non existent DIY for simply being able to use a "used" MS43 DME to match my EWS's rolling code. This way i can drive my car without spending an arm and a leg.

my questions are the following.

1) how can i backup (dump) my in-car DME so i have the rolling codes for my in-car DME. I don't mind it if it take place on bench or though ODBII cable


2) swap the EEPROM (which one) from my Old DME to ebay "Used" DME so it matches my EWS rolling codes and i can drive the car. (is this possible?)

3) use an in-circuit EEPROM programmer to replace the "Used" DME .bin file with my old DME's .bin file. So the rolling codes match and I can drive my car. (is this possible)

4) How can you bring a used DME to "Virgin state" so you can just active and program it through DIS.


I am not a very rich e46 owner and just trying to stay an informed one.

at least one more person in the thread had the DME and EWS error. So it just might help him too.

I can do the DME/ EWS sync using DIS as long i have the codes correct in both system..

please help out.

Thanks for your help in advance.


I posted here because everyone seemed to be the most informed here about DME or an e46.

Thanks !

possible, but unsoldering and resoldering the AM29F400 is pretty hard stuff.

but you have to be in this case. the needed software is ~5000$ and you will search several years for keys and cracks, if they exist at all.

do yourself a favor and search for an unused dme, they are out there and most of the time pretty cheap, much cheaper then virginizing a used one.

^There are some hacks to disable EWS. You can find these in ebay. Does anyone have experience?

Thank you very much for that fantastic and absolutely coherent reply. I better go looking for one of those new ones off the shelf. I figured it wasn't going to be that easy.

Thanks again. z

I am not sure if you can disable EWS 3 and later. Mine is a e46 and i am not sure if disabling them is an option.

They may work at EWS2 and EWS3, as stated, but unfortunally E46 is using EWS4.x

actually there is NO possibility tu turn ews off at MS43/45

It would be better to check this. BMW parts gives EWS4, but I'd really go and read it from the EWS unit itself in your car. EWS-delete-chip sellers claim it to work with EWS3 and MS43 ECU. Would it be so that older MS43 ECUs are with EWS3? I unfortunately don't have figure of mine, but here is one axample from ebay (http://www.ebay.de/itm/Steuergerat-B...item2326a6cf80)

to be honest, i wouldnīt trust an ebay seller. and specially i wouldnīt trust him when he states more then once, that he canīt test the hardware.

MS43 is always EWS4.x and canīt be deleted. if you find some emulator whos able to unlock EWS4.x iīm willing to buy it. but unfortunally there are many people wanting such an emulator and they are waiting long time

Well, there isn't an easy solution for this now. So I will be replacing DME and EWS with the real stuff. Programming it myself should save me a few bucks. I am glad though that i am learning all of these stuff. It pays to have a 2nd car. Kinda wish i had my awd bimmer in the crappy weather we are having today , ohh well. Thanks guys

Engine won't start if EWS is removed/disabled. Injectors will be turned off.

I checked mine, it's EWS3. The car is E46 with M54 and MS43, MY 2001. You can see yours by removing small glove box below light switch. It has two screws on top.

E46 IS using EWS3, thats correct. but sadly its using EWS3.3 instead of 3.2 and i havenīt found emulators for that kind of ews.

Good luck! Please, report us how it goes. I've a similar plan. :-).

For the other thing: I'm feeling I should start from very beginning. Even there are ready made .xdfs around, I'm not feeling very confident due to missing documentation and non-existent physical units.

IMO, these things have only partly been done, but I really haven't seen consistent documentation I'm striving for RE85 ethanol fuel. I believe I should have an access to acceleration enrichment, cold start, etc.

If you have a good for reverse engineering quide, I'd appreciated it. Please.

Before anybody gets angry: I'm NOT saying somebody should have done these for me and free. I'm just saying that open community seems to in the beginning. Commercial communitiy is far further.
