mercedes slk, read time

[Ospite i got petrol in my veins]

hi

today i read the ecu (bosch 2.0) from my 230k slk, and it takes more than 40 minutes, to save batery i just only disconect the trotthle and comp actuators, but it takes more than 40 minutes.

this monday i opened the ecu and dessoldered the eprom, and i thingh that i was faster than the obd interface.

the question is: with the obd interface, wath is the write time? it starts the fans like the others mercedes?

i have other thread on this forum to remove the speed limiter, any can help me?

best regards
