I can NOT buy a registered multiecuscan until I'm not sure that it is WORKING PROPERLY with my netbook and my interface.

Hello, I just wanted to thank you, i bought a Chinese-made ELM327 Bluetooth v1.5, had the same problem, only connected to ECU, now i desoldered R04 and all CAN systems work perfectly...
Thanks again, if it wasn't for you probably i'd have bought another interface...
