dcm 3.5 ford and g54

[kukukatsu]

Hi does anyone try to read ford dcm 3.5 ecu with galletto by JTAG and then write it (with gal v54 of course) by obd?? I know that i must do chekcsum before.

I read and write it with success by JTAG but I need to make some changes, ecu is sealed and i dont want to reopen it again.

Regards

no, dont.
read obd and mod and flash back via OBD!

on gal v54 only write by obd is possible. You have to read by jtag. And it works :)

And how about writing partial OBD readouts from other tools. Anyone tried ? Generally it shouldn't be issue but if someone can confirm...
