I don't know am i too foolish not to be able to connect Alfadiag, or this things is really hard to play with.
I brought THIS
lead from eBay yesterday, and today spend 2 hours trying to connect ECU. No success.
I really have no idea why.
As you may see this cable is USB - not COM ported - is that problem - 1 pic
I tryed when engine is on, when engine off but key in contact - same result....
Here few shots from my desktop -
I already spend more than 100 EU, try to connect Unidiag, Uniscan, - NOTHING!!!!!
Alfadiag states that One free RS323 port must be used - any idea what this mean - and how can i know if i have one?
As you may see on this
pictures, i have KWP2000 but still no success.
Bearing in mind that here in BG diagnostic like this in car services cost twice as this blue OBD lead, its better to buy another if this isnt working, than spending lot in services.
I forgot to mention - drivers for this lead coming with is installed as well.....
I have 8 USB ports on my PC, but now i can remember that when i trying to connect, configured was com 1 - can this be a problem too???
