So having a MED9 car and inspired by the work done on ME7.X here -> http://nefariousmotorsports.com/forum/index.php?topic=3027.0 (big thanks to everyone involved)
I decided to spend some time and try to figure out how the hack should be done on MED9. My car is relatively stock, but i have plans for the future
and would like to do the boost control the right way. I believe testing without boosting above 1.55 bar should be possible (which i plan to start soon) and i don't think i am confident enough to test this
on a big turbo setup yet... The list of maps attached is derived from 8P0907115K 040 a2l. A cross reference has been performed with the ME7.X list of maps
and i have flagged some of the maps with:

- not in ME7 FR - i haven't managed to find the maps in the Audi R4-5V T Quereinbau 132kW ME7.1 FR
- not in ME7 hack - maps present in both MED9 and ME7 FRs, but not included in the ME7.X list of maps. As far as i understand it and have read here in the forum,
every pressure variable has to be rescaled for the hack to work, so i don't know why some of those are not included. Maybe are not needed for the hack to work?
- there are also maps like KFLDRQ0 for example where ME7.X list says divide axis by 2, but the map unit is %/100hPa, so i am thinking the map values should also be divided by 2?

I hope there would be more MED9 enthusiasts with whom we can figure this out in the end.
