I sent an email to Launch about that. They said the X431's response is exactly the same as the "Factory" system (I assume PIWIS) and Porsche probably won't let you change it. I don't know if I believe that but there is nothing I can do other than live with it.I am not sure, but the Init Value may be the initial value of the speed that's needed to be obtained to turn it off after being activated. The first line of code may be the state it's always in until put into reverse. I'll check my car when I get the chance to see what parameters are in those fields then I'll also see what speed is needed to be obtained to turn it off. I'll also verify what I said earlier about pushing any of the buttons on the PCM to defeat the camera on state.
As a side note, one reason I bought the X431 is my late model Toyota Highlander was recently rear-ended and a parking sensor damaged. The "approved" shop wants $820 for vehicle diagnostics/turning off the sensor fault. I could not believe it but that is what they charge for driving it to Toyota and having Toyota turn off the fault. I am going to another shop that said if I want to drive it to Toyota and have them turn it off they would give me the $820. The X431 was less than that on Amazon so I bought it. But it does not find the sensor fault. So the X431 might be going back.
