First of all, the Piwis 2 interface is a lot more robust piece of equipment, compared to the cheesy and flimsy looking and feeling interface produced by Actia for Piwis 3.
Originally designed for the VW ODIS system, the VAS 6154 VCI is quite the service needy piece. [Breaks easily] not a hard comparison to make.
Is it worth to purchase Piwis 3 replace Piwis 2 now? Can the Piwis 2 compatible with Piwis 3 Software?
This answer for the question of whether Piwis 3 software can work with Piwis II Samtec HSX Interface?
Secondly, I thought the Piwis 3 for Porsche went cheap. [my humble opinion, way below Porsche standard!]
At the same time, there is a service from Poland and Ukraine [If I remember correctly] that can make the Samtec based Piwis 2 VCI work with Piwis 3.
Unfortunately, their charges are just as much and frankly cost prohibitive as the New Piwis 3 VCI. 2-3-4 thousand dollars for these VCIs is simply not reasonable for small operators.
They will come down in price just like the Chinese VCIs did for all manufacturers as the markets get saturated and folks are not buying them as eagerly as at the beginning of the Piwis 3 had.
They will get as much money as the market bares. [as much as people are willing to pay]
Your more pointed answers will not come in this tread Ibi. This is Cars Fan’s money-making tread, he will not volunteer any information, but if U start your own tread, U may be more likely to find out stuff.
What does the Piwis 3 updates replace Piwis 2?
Diagnostics application is used for communication with control units. You can search for, identify, code and control program units, read out the event memory, execute complex processes, change drive links and execute routines.
Guided fault finding (GFF) generates a test plan for a fault code. This test plan shows the best sequence for carrying out tests. GFF compiles a list of recommended tests, documents and wiring diagrams
Actual values/input signals functions display you the actual values and input signals of control units
Drive links/tests function displays the drive links of control units, allows you to change the parameters of these drive links and run test routines for individual control units
Maintenance/repairs function group – use this function to call up control unit-specific processes that cannot be implemented generically from the ODX data
Coding/programming function group – use this function to write coding values. Piwis 3 can code Values automatically or set manually. This function group includes (Automatic coding, Manual coding, Customer-specific settings, and Factory settings) coding modes
Logging – use this function to activate logging for diagnostics, guided fault finding (GFF) and measuring equipment applications. Temporary and permanent working log can be created
Filter – use this function to limit the view of the control units installed in the vehicle. In the diagnostic application, you can create, edit, activate, deactivate or assign filters
Wiring diagrams application is the representation of physical connections and layouts of circuits
Measuring equipment interface work for DC and AC voltage measurement, direct and alternating current measurement, diode testing, resistance measurement, continuity/open circuit testing, showing voltage, current and resistance over time (oscilloscope function)
