thanks for the reply,
most demo beside PCMSCAN identified or recognized the COM port which is COM4, but unable to identified the interface or establish communication to the interface. PCMSCAN and ODBWIZ connected to the device fine, of course PCMSCAN only let me see the rpm as you said. weird ... seems liked Windows 7 x32 doesn't have the right driver but it is not becaused OBDWIZ is working perfectly fine... i am new to the technology so as far as i can tell i get most function in OBDWIZ to work. i may need to take some snapshots or pull it out from the logs so you see what i am seeing.
