titanic,
That's one of the dirty little secrets in the ECU tuning industry. Some tuners will claim to have a "stock" program or return your car to "stock" but in fact they don't. It is simply a different set of settings and their custom programming is still in your ECU. Sometimes this programming leaves blank spaces in your ECU's memory, or values in registers that weren't there from the factory. Sometimes this is harmless sometimes it isn't, but it is not truly the stock Porsche programming. Since Softronic works with Porsche they have access to the programming provided by Porsche. The stock programming offered by Softronic is either of the two ECU versions offered fro the Cayman by Porsche, it is the exact file from Porsche, it is unmodified, it is byte or byte the same as the Porsche file because it is the Porsche file, most other tuners cannot make this claim. If they do, then ask them to verify it, get the Porsche file and their file and do a byte for byte comparison using some software tools and you'll likely find differences.

The point Softronic is trying to drive home is that if you get a "stock" program from another tuner that it isn't really the Porsche stock program, you can put it on a PIWIS and see it isn't from Porsche, it's been modified, whereas the stock program from Softronic IS the Porsche program and will show up as such on the PIWIS. For those concerned about going in for warranty work, or passing inspections, etc. they can return their car to true stock form, get their work/inspection done, then flash back to modified form if they want.

I doubt other tuners even know that there are 2 different Cayman ECU programs from Porsche at this point and what those differences are. The tuned Softronic files are built off the latest files from Porsche, I can tell you that in at least 2 instances of Cayman tuning files from other tuners that we've inspected both of their files originated from older Cayman programming from Porsche.

Hope that helps explain it.
