I urge you to consider using github. You can post your files, people can see differences quickly or even roll their own branch and host it there. Above all, there's a bug tracking system, wiki, and announcement system, which will be much easier for consumers of the project to follow than a forum.

Seeing differences between changes is key for tracking opensource projects. Also a clean way to comment on changes makes collaboration easy.

I am curious if any of this development will allow us to clone our DME's to a 2nd DME in case we experience DME failure.

I asked about github before, and its been brought up a couple more times. Anyone whose truly in the opensource community sees the benefits of github or similar locations, I hope you plan on pushing to git?

Also, I think an opensource tuning forum may be interesting. But I think perhaps this is very N54 centric

What exactly would we be pushing to git?

The communal xml or equivalent files with the latest table definitions? Past that I'm not sure what else there would be. Maybe once people start modifying roms those could be available.

That's my thought as well. At least for 99% of open source users who are using it edit values on existing tables and find new tables that are yet-to-be discovered. For those looking to rewrite DME firmware, that's another thing altogether and beyond the scope of what I'm assisting with at this point. My goal is to provide users with a user friendly tuning interface no more complicated to use, but offering more flexible mapping options, than ATR. Rombinhood's team is more focused on the hardware side of things at this point. And things are looking interesting from my perspective at least. Can't predict what the future holds though as development goes into FFWD once you put it in the hands of multiple developers.

This I don't know. I know we can change VINs and software versions between different DMEs. I haven't looked into the immobilizer code (never needed to). But I suspect this is the kind of stuff others can start digging into once this goes open source.

The tuning files can be swapped back and forth online normally... The title of this thread is, "Open Source N54 DME Flashing Project".


So the flashing software is open source. I'd like to have this source pushed to git as almost all normal community driven open source projects do push to a service like github.

Now if this is just a "New N54 DME Flashing Project with an emphasis on unlocked and sharable maps" well that is something different.


Here's a quote from his first post:

Emphasis on open source Flashing System, and a lack of emphasis on tuning. I love where this project is heading, but its becoming just a tuning tool, which is a shame because changing the DME logic is really the potentially amazing part.

This is part of the reason I'm interested in the source of the "Flashing" side of this. It helps dig deeper into the DME hopefully leading to areas in the firmware where we can change the logic of the DME itself rather than the limits or tuning tables, which is NOT nearly as interesting.

Swapping a DME requires messing with the CAS3(4?) and marrying the DME back to the other control units which get DME/VIN locked. I forget but I had done some detailed research on it before, but I know its possible. Its said the VIN is burned into the DME, but its not true, I came across a flasher that would do it, but they wanted like 2500 euros for it.

So my unproven but educated answer to this, is YES! We could soon find value in the 200 dollar DME's we find on ebay through this type of project, but the source would either need to be released where a group of individuals could work toward a common or different goals, or we have to rely on robin hood to save the day and give us gold and food.


EDIT: And no, I'm not demanding you release the source, that is not my claim to make, just hoping that you will!

As a coder, I know that making something open source is a personal decision you have to make yourself.

This would be awesome, not just for replacing faulty DME's, but having separate DME's for different situations. Rather than reflashing at the track, you can just quick swap a DME, which I can do in about 2-3 mins, as I no longer have the 8MM bolts that hold on my filter housing and trim etc.

The cost of DME's might actually go up, as they would be more then just paper weights.

We can only hope.

I have some CAS3/EWS4 ROMs, I880S, IF80S ROMs. E92 M3 ROMs (yeah, unrelated). And some other very interesting things related to the MSD80 DME & CAS/EWS system.

I kind of new this was going to turn this way, unfortunately. I guess we all know why

Don't get me wrong, it's still cool but was hoping for much more than having an alternative to "ATR" which is what it's all about now (a grudge...)

I'm afraid we need to learn to crawl before we can run. Let's master the flashing first. However, let's NOT stop there! Let's have a true open source project with modified code rather than just the maps. As long as there are people who want to reach the stars, we can do it. Even if one person of us would not take part in going forward, open source means the community can do it!

Do you have any information you can share on the algorithm/method used for calculating the checksum?

Hi all,

Interested in tuning my N54 with a flash tuning and was considering Cobb tuning since I've seen their advertisments. Almost embarrased to admit it but I'm cheap and would rather spend $100 for a cable than $900 for a tuning box or flash box, if that cable allows me to load a flash map that works just as well. How will this freeware system work? Can someone post a flash map and then I download that map to my car to have that performance?

COBB is around 750 and may be less shipped overnight here... it also has tons of maps to go with your mods, and ATR for even more flexibility.

Unless you are technically inclined to build your own flash or pay someone to do it for you, then go with COBB..

anyway, my 2 cents, decision is yours
