So as far as I understand it there is a way to prevent reading out the tune via OBD. Y"es I know you can still read it out via boot mode, but I think it would be nice to be able to "lock" in and make it more difficult for someone to just read out.
Has anyone figured out how to do this?

yes and no. just obd read you can use "ecusafe" which just turns of obd read for SOME tools, not all. You could also change the security string or seed key(havent tested this) as well. which will prevent a read. add no read into the file to block some tools as well. unfortunately, official tools seem to get blocked by these methods, some clone tools have this bypassed  |

Wouldn't changing the seed key also prevent writing?

on mbox, change 088cb from 0f to 00
once u do this it can't be undone on the file as far as i can tell so save as... i did it once and had to use boot mode to make revisions even after changing it back. I probably couldn't write one from scratch though, so idk what to do now. lol (sarcasm)

what do you mean it can't be undone? you can't change 088cb from 00 back to OF?

i changed it back to 0f and flashed the new file via boot mode it didn't seem to matter.
flashed a stock file and got obd read write back. flashed file revised back from obd read rite off to on and no dice.
let me know if you get different results.

Can you still connect with VCDS?
Do you know the name of the codeword or byte at that location?

I'm glad its working for you Josh  Its not a codeword. Its a hack. Not sure why NVR wants to do this though. Shouldn't all files be free? |

Just to confirm, writing over OBD is still possible?

No, josh is wrong. Only read is protected.
Write is fine. I never block off writing on my files.
