  1. No, never tried. But I likely will on the next DME 7.8 I see that is chipped. Here are screen shots that I was given of an 04 GT3 with Revo software hooked up to a PIWIS: It seems that PIWIS picked up the DME changes even though Revo claims their software to be undetectable... ???? dw
  2. Thanks for the TSB its helpful...but I think it comes down to theory vs reality. Yes in theory there is a function that runs checksum...I think it uses a MD5 hash value actually. But in reality it doesn't actually detect most chips because of specific meaures taken to circumvent detection. Of course various tuners use different techniques to accomplish their goals. Some edit the bosch code directly, some write a whole new program and replace the OE one, some put new tables only in empty areas of the ROM and direct the OE program to access the values, some use mutiplier tables to alter outpu
  3. I've recently had somebody tell me that PCA is going to start using PIWIS to scan cars at all upcoming events for aftermarket tuning software on the ECU. I'm having trouble wrapping my head around how this is possible. Since most tuners retain OE values, and display same paramaters as OE software, a simple scan would not show any change. This includes flash counters which are not usually triggered by tuners. The only possible way as I see it would be to either do a checksum on the file and compare it to ALL known factory files for that model/year. Which could be many. or do a actual binary
  4. Its been a little while...anybody have commensts on long term use of this tool, updates, etc.. Still no brake blead function?? dw
  5. I am doing a PSS9 install in an 06 cayman S and had some trouble figuring out how to get all the trim removed from the top of the rear strut towers. I read the article in the install posted on caymanclub, but it showed the tab on the speaker cover holding in the last torx screw being cut to avoid removing the head liner on the c pillar. I'd rather not do it this way and risk additional squeeks and rattles. But cannot find a decent diagram that shows the rear trim and its clips, etc... Can anybody that has pulled this out on their own offer some tips?? Thanks Dave
