Here is a first shot of my newest project: Getting me a Porsche System Tester, aka PST2. The PST2 was the successor to the Bosch 'Hammer' (KTS301). It can deal with a lot of the newer cars. It really is a 80486-based handheld computer with a B/W LCD display with 640x480 pixels.
In this particular configuration it runs a crippled version of Windows 3.1 and Porsche's software. It also has an integrated URI module that can measure voltages, currents, and resistances. Soul Calibur Iii Jpn Iso Burner. The URI module runs on a 68HC11 mircocontroler and communicates via a serial port to the main computer. Bosch made a generic version called KTS 500 for all vehicles running OBD-II and a special Porsche-only version called PST2. And like everything else the Porsche version commands a rather hefty Porsche tax when trying to find used ones.
So I set out to 'convert' a generic Bosch KTS 500 into a PST2. After running into some hurdles I finally figured out how to 'trick' the software to ignore the green outside and play with the Bosch hardware.
Next, I have to convert the OBD-II cable into the Porsche version and see if I can do some scanning. Village idiot, I haven't even thought that far. At this point my main goal is to get it to run properly and learn things in the process. I like tinkering with that sort of stuff. But if someone is interested we can certainly talk. A couple of years ago I did a similar project converting an ordinary KTS300 into a Hammer. I had to fabricate a PCB from scratch, a first for me.

This should have been a pretty straight forward task. Plug the 8-pin AMP connector that goes into the Hamer into the short Bosch adapter and that goes into the PST2. However, despite numerous tries the PST2 did not find the DME. What a bummer. I think I have to chase the signals and check if something is mis-wired. Wired, the Hammer still finds the DME just fine.
Maybe it is not as demanding and does not need the L-line. The good news: Out of sheer frustration I went ahead and hooked the KTS 500 cable up to the 996. And surprise surprise the PST2 found the DME. I knew at the time that the standard Bosch-OBD2 cable is different from the Porsche version.
So with new-found inspiration I went ahead and converted the cable to Porsche specificatons. And that lead to full success. See for yourself. First, the PST scans the vehicle and highlights all control units found in the car. For the C4 coupe it found the PSM and all other moduls expected.

So I went ahead and erased the faults: And voila, the next scan comes up clean. No more fault codes. So my first little job has been completed successfully: Ingo. Jamie, To answer your first question: Yes you can write to any ECU in the car and Porsche makes extensive use of that. Starting with the 996/986 everything is stored in EEPROM memory. ISP (In System Programming) is much easier than having to open the box and replace a memory chip. However, first of all the PST2 is far away from an open book.
It has structured menu items to change settings in the ECU. Things like settings for the POSIP, engine #, etc.
You can also re-flash parts of the ECU or the instrument cluster to a new box in case it needs replacement. Some writeable areas are protected by binary security pass phrases. Each car is identified by its VIN number. Porsche maintains a data base with these keys for each car. There are several areas that are protected. Things like the instrument cluster, the immobilizer, remote entry, alarm, vehicle history just to name a few. If you want to write to those areas you need the specific key for your car from Porsche.
I have seen a printout at the dealership for a 997 with all its keys. There were at least 10 if not more. If a service technician needs to perform a certain operation he needs to talk to his supervisor to get the key. Only the supervisors have access to these keys. My guess is that Porsche use some sort of AES or DES encryption.
That’s what the pass phrases look like. If you want to change the mapping for an engine you would have to reverse-engineer the binary image of the ECU, get the checksums right and inject it back into the PST2 software to get it to write the modded image to the ECU. But I don’t want to kill my C4 just yet. So I don’t think I am going to do much in that line. There are other aftermarket solutions out there that can do this.
