in second way, in this moment im talking with a programmer that offer me in a solution. first step is encript some maps, this force to cloner to use "complete file".if use it..... then a few minutes/hours. the car stop, and erase flash eprom and eeprom..........
what do yo think?

The only things unique are the EEPROM and FLASH. If you copy both over your software will not know that it is running on another car.
It is always possible to copy.

I also am STRONGLY against pouring CRAP into another persons ECU.
This is just ridiculous. It's not your ECU, and if your customer wants it tuned later, then they probably have to buy a new ECU.
If I was your client and you did this, I would probably sue you... especially if it was one of the newer more expensive ECU's.

When you buy a tune you sign a document allowing the tuner to do whatever modifications they want to achieve what they promised and that includes disclaimers of all sorts. APR has such document which I signed years ago when I purchased my stage 1 tune.

You are still pouring crap into an ECU.
Look, this is not an encryption board, or anything like this.
If the ECU has to be bootmoded in the future or if you want to get your car tuned by someone, it can't be done safely without risking damage to the ECU.

One thing is to solder on an encryption board and change data - modifications that can be reversed by anyone who knows how to solder.
The other is dumping a giant turd into the ECU.

I'm personally not a fan of someone (a client) having their hardware physically ruined with epoxy/etc without the client having very explicit knowledge of it and approving it.

As far as encryption goes, it seems decently effective, I mean just look at how many APR tunes people have looked at over here ha.

I'd say either encrypt, disable OBD reading, and/or cookies in the tune as an signature.  prj's way sounds effective too.

Disable the upload service...
But that won't save it from anyone who is serious about reading it.

I understand that.

If anyone ever did this to one of my ECU's I would throw it through their shop or car window.

The idea of destroying an ECU to prevent someone copying a file is just crazy.

Agreed. This is stupid. LOL @ tuners who think their shit doesn't stink. Sorry, nothing you are doing is special, get over it.

Yeah, they do that to their "BT" tunes... Best part is their tunes aren't even worth stealing/using they're so bad.

right, but thats not a bt tune. just a regular stg2 hpfp file.
its hard to tell, but most of the bdm pads themselves were scratched off the board. so i soldered to the trace and to the few pads that were left.

Ah, that explains the missing epoxy then... their 1.8T and VR6 BT tunes used have the ECU/flash doused in epoxy

I think the best protection is custom code + script panel. A lot of headache, but I think this is the way how APR, Revo etc protect their files. And if somebody can decrypt it, it means he is not noob and can make a good tuned file by himself.
