Stasis Revo Group first to flash our cars without removing ECU

B8 S4

What do you think? Is it just from reverse engineering a security algorithm to calculate a key on any given ECU? I have to wonder what the methodology is to figure this out. Get a couple of servers and just hammer away at it until you figure it out, or have an insider friend at Audi and/or a dealership that will allow your engineers to reverse engineer it via some sort of packet sniffing when using the dealer’s computers to flash the ECU.

That’s really cool. And it’s about time. Arin hinted in a thread recently that APR may be introducing something similar down the road.

I doubt it was brute force. Arin has said before that these ECUs use 1024-bit RSA encryption. Assuming that is true for the B8.5 ECU also, it’s more likely that there is some sort of flaw in Audi’s implementation of the encryption that they have found and managed to exploit.

Yeah, must be a flaw exploited on the SiMOS8.5, since Revo/Stasis port FLASH is not available on the SiMOS8.4

And now APR has it available…

So they have to fly out there and flash in person? Ah, bummer! Our dealers can do it in house without us there. : )

I hinted months and months back there’s a good reason to wait. ; )

Any plans for the upgraded CPS for the facelift? I’d like an upgraded intercooler for stage 2.

BTW, it will cost me $750 extra to switch from GIAC to APR. If you can make a deal on a CPS kit and a pulley/tune I’d do it…

GIAC S1 ($1350) + Power play ($1,299)= $2,649
GIAC S1 ($1350) + GIAC S2= $1899

nevermind, wrong thread
