[Pieter] is in the process of adding a turbo package to his ride. He needed a status display for the boost but didn’t have a good way to mount an additional display. He came up with the idea of using the LCD screen that’s already in the dashboard, but the specs for it were not available. Wielding his hard-earned hacking skills [Pieter] used a logic analyzer to sniff out the communications to the screen. He built a controller board that overrides the data coming in from the head unit. The board is also able to query the car’s computer for data and display it in any format you want. What he ends up with is a stock look that he can customize for his needs. Nice!

Sure, now it goes through. LOL.
I know it’s an old thread, but I’m very curious about getting into the OS on my Determinator. I was mulling it over, and it occurs to me that the unlocking and reverse engineering discussed in this thread doesn’t *necessarily* constitute software piracy. I’m no copyright attorney, but it seems to me that if you buy the device, and the software is already on it, the act of unlocking it is not stealing software. Neither is disclosing the method by which it can be unlocked an act of piracy. I believe it is comparable to manipulating region codes on DVD drives. A better analogy might be: if your vehicle is capable of producting 200 HP, but the ECM limits the engine’s output to 160 HP for the sake of emissions, crash test safety standards or whatever, you are not violating any law in simply reprogramming the ECM to perform better. It might technically be unlawful to operate that vehicle on public streets after such a mod, but the mod itself is not grounds for litigation. The vehicle, ECM, engine, etc. are already yours, and therefore yours to mess with. I also have a hunch that there is a fair use and/or public domain angle to this question, since virtually everything the scan tool does is based on other companies’ software and interface algorithms, older versions of the system are no longer supported by OTC, and the OS is not proprietary OTC software (I think). In any case, I’ll be digging in to see what I can do, and will post what I find here. If anyone else out there is still interested, feel free to emai me at uvulus1ATyahoo.com.
Hi all, I know it’s an old thread, but I’m very curious about getting into the OS on my Determinator. I was mulling it over, and it occurs to me that the unlocking and reverse engineering discussed in this thread doesn’t *necessarily* constitute software piracy. I’m no copyright attorney, but it seems to me that if you buy the device, and the software is already on it, the act of unlocking it is not the same as stealing software. I believe it is more comparable to manipulating region codes on DVD drives. A better analogy might be: if your vehicle’s engine is capable of producing 200 HP, but the ECM is programmed to limit the engine’s output to 160 HP for the sake of emissions or crash test safety ratings or whatever, you are not violating any law in simply reprogramming the ECM to deliver better performance. It might be technically unlawful to operate that vehicle on public streets after performing such a mod, but the mod itself is not grounds for legal action. The vehicle, ECM, engine, etc. are already yours, and therefore are yours to mess with. I also suspect that there is a fair use and/or public domain component to this, since virtually everything that the scan tool does is based on other companies’ software and interface algorithms, and afaik, the OS itself is not proprietary to OTC. I also very much doubt that divulging the methods by which one has unlocked or otherwise modified their scan tool is illegal. If it were, there would be thousands of successful lawsuits against developers who root and unlock android and ios devices and publicly post the instructions. This is basic first amendment stuff. In any case, I will be digging in to see what I can do on my scanner, and posting my findings here. If anyone out there is still interested, don’t hesitate to email me at uvulus1@yahoo.com.
Oops, sorry for double post. Took a while for the first one to show up.
