Better backup that data first.
Are you able to write to the maps yet?
I guess from that jumble you will still have to figure out where everything is stored.
Do you have a reference of some kind to go by or do you have to reverse engineer it?

Yes it’s backed up; yes I can write to the map, yes reverse engineering is in the works.

Kashmir, what exactly is your exigence for mapping the motronic? I am quite interested in your project and wish you the best of luck. As a member of the boxster enthusiasts, you are free to borrow a durametric if the need arises. Good luck!

Fair enough.  You do as any red blooded man does with cars. Share with the forum and tell how it goes with us.

I'm also a computer wiz but hacking hex code has never been something I have really had a chance to do.
I'm interested in your work so keep us updated on this thread, wish I could help in some way.
I suppose once you figure out the structure and function you can wrap it all up into a program that lets folks do their own tweaks, like the race tuners.
I wonder how they do it or do they replace the Engine Control Unit with something custom that has be developed for tuning?
