Jpdiag

Hi, I'm getting this error while trying to connect to my ecu:

CANT INIT ELM!
check your setting COM and your COM speed

im quite sure I have installed the correct FTDI CABLE DRIVER (CDM20824)

maybe i got wrong cable:

any help WILL BE VERY APPRECIATED!!!

ok, its a epically great tool anyway!
should I use mecodiag or jpdiag?

hello guys! I'm just wondering if this software can also used to change tune!
