I posted the following question in teh RENNLIST.
______________
I was wondering if anyone of you has actually owned and used one of these Chinese made PIWIS tester II?

I would appreciate if you could actually give me factual information as opposed to speculations that I have read in many sites. Moreover, no need to insult Chinese manufacturers, as many have done on this site and many others, since I own and use a Chinese made clone STAR Diagnostic system form my Mercedes, and am extremely satisfied with its performance.

Someone told me that I only need PIWIS I (as opposed to the PIWIS II), in that for my vintage Porsche 996 (2201), the II does not work as well as the I does.

Moreoevr, the person who answered told me that I would only need a cable, which looks very similar to the Duramteric cable (which I own). The purpose of opting for PIWIS, i sthat I liek to also be able to program ignition key, etc.

Your factual comments are much appreciated in advance.
Cheers,
Zack
