I recently bought a 2012 135i coupe DCT .. It came with a few upgrades : Downpipe / software / charge pipe upgrade ... The dealer could not tell me anything about the stage 2 software upgrade .. It is hard wired ... Is there anyway of determineingwhat software was used...

I think you need to understand how a tune is applied, to understand the answer.

How it works is, you don't actually get the source code of the ECU. Tuners usually find a way to dump the code, reverse engineer it to figure out where parameters can be changed. So when they apply a tune, its basically just settings that they change to give you that "tune" that they would have tweaked after testing multiple different variations.

Thats one way, to change the settings. Another way is obviously something that sits inbetween, interpret values from sensors and the ecu, and then change it on the fly to let the engine do different things, or give it that tune.

Either way, there isn't a stamp on anything that says I have applied Tinuva's super duper boost v2.1 tune.

Finding physical changes are usually much easier than finding what tune is on there. It would mean, someone needs copies of all tunes made ever for your car, dump your cars current tune and compare it to all the templates out there to find a match.

So in short, its not impossible but damn near it. Its easier to just apply another tune over the current one if you want to know what is on there.

Do you mean "was it tuned by Tuner A, Tuner B or Tuner C?"

I have an enet cable, not selling it but can make a plan if you just need to use it once off type of thing.

I am around the Fourways area.

Enet cable doesnt work on E series.

As for the software, you need to download the MHD app on your phone/tablet and then you can do the flashing.
Just note, you would need the account details that originally bought this software so that you have the license details, otherwise you would need to buy the licenses again.
You can speak to MHD support and see if they would move the licenses from that account to yours.

Taking a chance that someone has an Enet cable that they wouldnt mind loaning to me for a day or few hours to code carplay.
Seems none of the local suppliers have stock.

Thanks gents.

Thanks now I need to get the mhd software ...
However easy this sounds it aint, you're gonna have to fork out around 13k depending on what package you need with what maps if you don't get the previous credentials. FYI, MHD does not transfer ownership, you need to buy your own stuff. Only BM3 transfers if need be. Been there, got the t-shirt.
