i see everybody talking about it and now i know what it is , so i was wondering which brand is better, any suggestions.

 

Ross-Tech ive heard thrown around quit a bit. Correct me if im wrong but i think its reliable

 

typically the KL adapter is not a problem - the problem was to connect KL COM adatpter to my laptop with only USB ports :-)

 

There are lots of serial to USB adaptors available. Just make sure the one you get is High speed. I believe Ross Tech and other list recomendations on their web sites.

 

the recommended USBCOM is PCIMCA type, because many low price USB adapters DO NOT EMULATE CSD, RTC pins used by the adapther. I know that Prolific USB COM seems to work ok.

 

what can you do with these things?

o ok, so anything cool i can do with it? lol other than the basic diagnostic and all that

 

Ross-tech is the ONLY place for the software, but just about any ODBII cable will work. But if you want to troubleshoot & fix your own car, buy the whole version from Ross-Tech, it WILL pay for it's self after ONE use!

 

how much how much[:-]
