VNCI PT3G VCI for PIWIS 3

 I purchased a PIWIS 3 setup from Mars here on Rennlist and the purchase included a VNCI PT3G VCI (Virtual Communications Interface) that provides the connectivity between your OBD-II equipped Porsche and the PIWIS software.  I’ve had it for less than two months and found it to be a solid, dependable device.  I ultimately decided to upgrade to a TabScan T6PT3G VCI in favor of the VNCI PT3G.  A bit more expensive, but there are some additional features that come with the TabScan device that lured me away from the VNCI PT3G.  If Mars sells this device, you can be sure that it is reliable.  ** FULL DISCLOSURE ** - I did encounter a protocol issue when interrogating my 2004 GT3.  The PIWIS hung on the data exchange with the ABS Controller.  Ultimately, I participated in a problem determination session with the VNCI developers who took trace data to determine how best to correct the issue.  I suspect that they will be releasing a new set of drivers shortly.  This is the ONLY instance I found where the VNCI device did not work as it should.  If you have a 996, you *may* encounter this same situation.  997's and up seem to be just fine.



 I am selling the VNCI PT3G VCI plus two USB cables for $250 (which will include shipping via USPS)  This is a firm price.

VNCI Porsche PT3G: Device Manager and Driver Installation Guide

The VNCI PT3G diagnostic scanner is compatible with original PIWIS drivers and software without the need for cracked or patched versions. It serves as a replacement for the original Porsche diagnostic tool PT3G, supporting a wide range of Porsche models from 1996 to the present, including the 9PA, 9YA, 9YB, 92A, 95B, 918, 970, 971, 981, 982, 986, 987, 991, 992, 996, 997, Y1A, and more.

Why Choose VNCI Porsche PT3G?

Compared to the OEM PT3G, custom VAS 615A, and other PT3G tools, the VNCI PT3G offers several advantages:

• Compatibility: Supports original PIWIS drivers, CAN FD/DOIP, multiple versions of PIWIS, and the KW71 protocol (vehicles before the 1995 model year).
• Coverage: Works with Porsche vehicles from 1996 to 2023.
• Ease of Use: Plug and play with free firmware updates.

• Custom VAS 615A: Modifies PIWIS software drivers based on VAS6154A hardware but has incomplete protocol layer communication logic, limiting diagnostic, programming, and immobilizer functions.
• Other Tools: Do not support original PIWIS drivers, KW71 protocol, and often require software patches, making them incompatible with older Porsche vehicles.
