I have a2l/hex, supermappack, function sheets for all McLaren's through P13 (the 570s). Contact me if interested, not cheap. You can also very easily patch in what ever you want to log in $22 with IDA and the a2l for the ram addresses.
I would not waste time on the $22 UDS logger, its too slow and i limited to what McLaren wanted. You can't even log injector timing so you can't come up with IDC's (unless you patch in the code to like I did). I would put the efforts into using CCP where you can log all ram and realtime tune. You need a2l's for that though and also seed/key algo's which I have as well.
@crystal_imprezav If available, (it was a long time ago I know) I'm interested in a2l/hex, supermappack, function sheets for ME17.8.3.2 specifically for CALID 11M2572.CP04. My challenge is that I'm blind on the correct RAM addresses to log for basic tuning parameters like; knock by cylinder, ignition angle by cylinder, injector open time, etc. because the documentation is just not readily available.
