Hey guys, I'm trying to get the file out of my ECU and I get connected successfully. I can read the ECU info successfully. But when I press the "full read flash"-button I get "Reading ECU-flash memory failed"-error message. I've tried multiple Baud-speed settings and I've opened up my ECU to check the chip that's in it so I use the correct memory layout.

The car is a 2.7T Audi A6 AJK engine put into an B5 A4, 1.8TQ originally, ECU number 4b0907551G.

Could you elaborate? Can't find anything in the search-bar, tried putting 0x00 in the security seed under kwp2000 settings-bar in the software, but it failed also
