[QUOTE="ZeroSVT, post: 14806644, member: 81012"] Lets get specific then. What "locked" portions of the ECU do you think exist? Line by line of what coding? Specifically FLASH? or? An engineer just can't just JTAG the ecu and suck down the FLASH contents and start inspecting. There is protection there, to protect certain areas of FLASH. If that was the case, things would be going a lot more different for aftermarket world. Protection Fuses are they to protect, once they are set, there is no unsetting them. I have a feeling you may be referring to Checksum calculations/storage, and thinking they may be stored in some "secret" location. As long as you writing through services 2E, 3D, 35, or 36 you will have no worries. The devices you sale, look an awful lot like a Vehicle Delivery Device... Interesting... -Matt [/QUOTE]
