Piwis 2, Porsche’s proprietary diagnostic and programming system, is essential for maintaining and repairing Porsche vehicles. This guide will provide valuable information about Piwis 2, including where to purchase it, necessary hardware requirements, and important considerations for using the system.
Choosing the Right Piwis 2 Version
Selecting the correct Piwis 2 version depends on the specific Porsche models you intend to work with. Not all versions include the development mode, a crucial feature for advanced diagnostics and programming. Consider the year and model of your Porsche when making your decision. For older models like the 997, software version 37.250 is often sufficient. Newer models, such as the Cayenne, Macan, or GT4, may require the latest Piwis 2 version. Consulting with reputable vendors or experienced Porsche technicians can help you determine the appropriate version for your needs. Belauto, a well-regarded vendor within the Porsche community, often offers special deals on Piwis 2 systems, including packages with multiple software versions.
Hardware Requirements for Piwis 2
Running Piwis 2 requires specific hardware. You’ll need a compatible laptop and a Vehicle Communication Interface (VCI).
- Laptop: While older Macs (pre-M1) can run Piwis 2 via virtualization software like VMware Fusion, a more straightforward approach is using a Windows laptop. Affordable options, like the Lenovo Yoga, coupled with a pre-configured Piwis 2 SSD from a vendor like Belauto, offer a convenient solution.
- VCI: The VCI connects the laptop to the vehicle’s OBD-II port. Firmware version 1.6.6, previously available on platforms like eBay and AliExpress, is compatible with Piwis 2. Prices for VCIs can fluctuate, so research current market prices before purchasing.
Power Supply Considerations for Piwis 2
Using Piwis 2 requires a stable and powerful power supply connected to the vehicle. This is crucial to prevent interruptions during diagnostics and programming, which can potentially damage the vehicle’s electronic systems.
- Amperage Requirements: A 997 requires a 40-amp power supply, while newer Porsches often need 75-100 amps. Standard battery chargers are insufficient for this purpose.
- Recommended Power Supplies: Dedicated power supplies like the Powermax 55 amp model are recommended. Alternatives include repurposed computer power supplies, which require technical knowledge to modify. Resources on converting computer power supplies are available online, especially within BMW coding communities and RC model groups. Vendors specializing in RV supplies and CB radios also carry suitable power supplies.
Where to Buy Piwis 2
Several options exist for acquiring a Piwis 2 system:
- Reputable Vendors: Vendors like Belauto specialize in providing pre-configured Piwis 2 systems, offering convenience and support.
- Online Marketplaces: While VCIs may be found on platforms like eBay and AliExpress, purchasing complete systems from reputable vendors is generally recommended for reliability and support.
- Community Forums: Online forums dedicated to Porsche enthusiasts, such as Rennlist, offer valuable insights into purchasing Piwis 2, including vendor recommendations, current pricing, and troubleshooting advice. Researching and engaging with these communities can help you make informed decisions.
