I wonder what this means though. Basic adjustements or a fully decrypted and table translated ecu?

Yes, i would want to see logs as well and posts of some tables they modify. No idea how they would able to crack the digital signature but maybe it's an exploit somewhere. Either way, eager for more news.

It would take months to do that. But removing speed limiter indicates that they passed the encryption which means those things will come eventually.

Usually that stuff isn't encrypted. Rather CRC checked. The image/firmware is signed....the same way the image for your iPhone is. Finding where the tables are isn't hard...finding what the table are is, thats were IDA Pro becomes your best friend.

Pretty sure they just found a way around the encryption rather than breaking the encryption based on what I'm hearing behind the scenes.

again, it's not encryption that was "cracked." If encryption was that easy to break, we would not be doing our banking online.
