How to read & write Bosch ME7.4.6

by **jovaan** » Wed Apr 23, 2014 9:56 pm

Is it possible to read and write 7.4.6 flash via OBD II port, using MPPS 13.02? Or only possible to do it in bench, via boot mode?

...also, what should the .bin file size be, I tried to read ecu via OBD II with mpps 13.02 and it resulted in only 64kb file size.

Thanks for your answers.

Next thing is to connect wires to the ECU pin out,
you have 3 pair of connectors on ecu: 1,2,3, you will use 2 and 3:(4-pair-of-connectors-123.jpg)

CONNECTOR 2
F4 = +12V
H2 = K-LINE

CONNECTOR 3
M4 = ground
M3 = +12V

I have an update to the pin out. My 406 coupe V6 has another configuration, maybe starting with DAM 8850, but not completely sure. I used the following pins:

CONNECTOR 1
H1 = ground

CONNECTOR 2
B4 = +12V (ignition)
H2 = K-LINE
L4 = ground
M4 = ground

CONNECTOR 3
L3 = +12V
M4 = ground

If anybody is interested in the whole pin out, let me know...
