So, how hard would it be to 'add' this needed service to the ME7 ecus?
Also, what few ME7 ECUs are you referring to that have the needed service?
Thanks,

'Adding' this would be not impossible but really hard. Too hard compared to the gain.
Still no high performance logging with this method, since you can log only 8 variables per
logging request and the ecu has to do the whole data conversion itself, which is quite a lot
of instructions to perform for each log request.
So far I saw these two images with support for readDBLI:
EPK = 40/1/ME7.5/3/4016.31//24E/Dst06o/071002//
- '0261207931' (SSECUHN)
- '1037366920' (SSECUSN)
- '4B0906018DA ' (VAG part number)
- '0006' (VAG sw number)
EPK = 40/1/ME7.5/5/4016.32//24E/Dst02o/180902//
- '0261207941' (SSECUHN)
- '1037366871' (SSECUSN)
- '8E0909518AH ' (VAG part number)
- '0002' (VAG sw number)
Or....
can we modify the flash to allow a higher baud rate via kwp1281?
Raising the baud rate could be relatively easy implemented, but the gain would be nearly zero.
The kwp1281 protocol requests echo bytes to be sent by the communication
partner for each transmitted byte, so the "round-trip-time" is limiting. This is mostly
defined by the time slices the ecu uses for processing data, which is 10ms,
the baud rate is not the limiting factor here. Plus you get only four variables per log request.
