Question about tune file

[bmwlover0725]

So I this is a double question

1. If I flash everything in ISTA/P (I need to program my VIN to a new satellite radio module), will I lose my tune? I have a BPM tune and have lost the original file. If I do lose it, is the file recoverable? I'm sure I can ask BPM this part, but I'm just wondering if anyone has needed a duplicate file in the past.

2. Has anyone had experience with the bimmergeeks expert (not pro) cable? It claims to be able to flash any module on an E chassis including the MOST interface. I've read reports of it working well for this, but I'm curious as to whether or not anyone here has used it on our vehicles. I know that M3's have to have the EWS coded to match the DME from what I've hear and I want to ensure that this cable will do that.

TIA, sorry for the long read.

All you need to do is flash the vin to the new sat module with ncs or tool32 there is no need to use ista.

I'm not experienced with these, but I could probably figure it out based on what I've read so far. It seems pretty simple to change a VIN with winkfp actually so I'll probably go with that. Has anyone had experience with the cable I mentioned?

I know that this isn't exactly the place for radio stuff, but I figured I'd update for anyone who finds this thread. The module doesn't need to be programmed to the VIN. I ended up getting a bad module. As far as the expert cable goes, I'll update when I try flashing something else with it.

Yes, I have flashed the DME quite a few times using the BimmerGeeks Pro cable. No problems with that using WinKFP and flashing software written by TerraPhantom

Have not tried to update the CIC however.

You also asked "I know that M3's have to have the EWS coded to match the DME from what I've hear and I want to ensure that this cable will do that."
Choice of cable is irrelevant for this operation. It cannot be done using inexpensive software via OBDII. If, for example, your DME has failed and you wish to replace it with a used one, you are SOL without very special knowledge and equipment. The practical alternatives are a) buy a very expensive new one from BMW, who will do the necessary SK write at the factory or b) read the SK from your existing DME using Terra's software (if it can still communicate via OBDII), encode it properly for EWS4 systems then use an EPROM programmer to write it to a chip in the CAS.
