Yeah, I should have gone the long coding route from day one. I bleed hex, just tell me if you want little or big endian output. I've lots of experience in hacking embedded systems that way, but assumed there would be heavy protection by VW on making changes at that level. Very surprising to see that isn't the case for a lot of things. Time to upgrade the ODB11 to pro and get hexing!

On another note, nice to see that the ever efficient Germans have maximised memory usage by utilising bit level coding, none of this single function to a byte wastefulness I see in countless other systems. Their coders must have, like me, grown up in 8-bit days where 16kB or so was all you had to play with.
