The difference between serial and bdm

[nero72]

Hi guys, as the title suggests, what are the differences between reading in the bdm port and a serial port, what does this mean if I once read in bdm, then I read on the serial line can I change the rewrite and the ecu I get stuckI can rewrite it in the bdm cannot go back, sorry for the confusion, I hope that I have understood, greetings, Gianfranco.

In the meantime, let's clarify :
do the reading total bdm (flash , micro , seprom)
then you can do what you want
to the maximum restores all

the difference between reading the obd and bdm in the suitable, and that in the obd not read all of the content
then do not read the mico , and seprom (key code ,frame fitting, etc, etc encoding injectors km paths, etc.).
regards

Ok, I understand, I have to make a copy in the bdm of my two-machine hello and thanks again faberecu, good make.

I believe you can also read the flash in the bdm and rewrite, then a second time with the serial.
For example, reading bdm (only flash) write gallo serial.

[nero72]

understood, but if the ecu is responding in writing to the serial, I have to desolder the eprom to rewrite, or just connect to the ecu in the bdm and rewrite all and good night. YOU ARE GREAT.

If it is blocked, you need the bdm and rewrite everything.

Precisely in serial would remain locked.

we clarify that not all the units you can read in the bdm.

[nero72]

Okay, but most of the units can be read out ,to me is for my and a few friends, I do not for work, I am the programmer of the plc.

Watch then if you have to take c'? the list of cars supported, just look for the network and will adjust accordingly. Maybe you should take a Rooster v2...
