I've arranged to have one of our Mercedes shop foremen plug into my SRT to see what can be done. Assuming it works, I've got a few things I'd like to try.
1) does it completely disable ESP/BAS/ABS/ETC or do those functions still work.
2) will the vehicle stay in dyno mode after multiple restarts.
3) can we map the steps necessary and repeat them on a hand held scanner instead of the Mercedes diagnostic equipment.
4) are there any visible indications when the car is in dyno mode.
HDDP: do you want ESP to remain active in it's reduced "off" mode or would you prefer it to be disabled?
What other things would you guys care to look at?
ASFAIK 'dynomode' on the MB cars is a temporary mode that is reset after the ignition is cycled. The visible indication is the word 'dynomode' (or similar) on the multimode dash display, which we don't have!
HDDP has done more in depth research on this than me and he had it confirmed by more than one MB tuning specialist (at least to their knowledge) that there is no way of entering 'dynomode' from the DRBIII etc. If you find a way then that's fantastic, but somehow I think you may draw a blank.
