For a Porsche 981, choosing between PIWIS 2 and PIWIS 3 involves weighing up the functionalities specific to this model and considering potential updates or backward compatibility issues:
- PIWIS 2 vs PIWIS 3:
- PIWIS 2: This tool covers Porsche models up to around 2017, which includes the 981 series. It’s well-suited for older models and generally sufficient for basic diagnostics, programming, and control unit adaptations. It’s typically less expensive and can handle most of the programming tasks needed for the 981.
- PIWIS 3: While it supports newer models and can service vehicles up to the present year, PIWIS 3 offers broader capabilities and supports more advanced systems, including newer electronics and software updates. However, it’s more expensive, and some users report issues with backward compatibility, such as programming changes not holding or requiring multiple attempts.
- Purchasing a Unit:
- Vendors like Autonumen are often recommended for purchasing complete units ready to use, as they typically offer good customer support and ready-to-use setups with the necessary software and hardware. It’s advisable to seek recent reviews and user feedback specific to Porsche diagnostics to ensure the chosen vendor meets your expectations.
- Programming and Customization:
- The extent of programmable options with PIWIS tools varies by model and software version. Generally, you can expect to modify settings like rain sensor activation, driving mode characteristics, and light settings among others. The specific steps for programming these options are typically found in the tool’s software, guided by menus and sometimes aided by online forums or user communities.
Given your specific scenario with a Porsche 981 and considering the balance between functionality and cost:
- PIWIS 2 seems the more practical choice unless you require the latest diagnostic features that PIWIS 3 provides for newer models or unless there are specific newer functionalities that are crucial for your needs.
For compiling a list of programmable items for the 981, consulting specific forums like Rennlist, 6SpeedOnline, or Planet-9 can be invaluable. These communities often have detailed posts and guides based on user experiences, which can help you determine exactly what can be programmed and how to do it.
