Iv sent up my own little custom module for brute-forcing information between the BCM and also at the ECU. So far so good!
During this R&D, I realised I can sit the module between the ECU, and laptop (Or scantool) that can 'bend' received messages from both scantool and ECU.
I actually hooked up both the tech2, and also SOE and realised that I can modify the received vin and serial and still process everything else the same. This includes performing full TIS updates to the device.
With that in mind. Wouldnt the entire tuning market completely collapse with such a device? I mean, I havent found a single commercial tuning software that does not rely on the vin/serial for locking. Since technically its their only real system to attach to. Primarily looking at Holdens and Fords, but it seems all other CAN based vehicles have the same situation.
Even if a little 'marker' is saved in the flash, this could be modified on the fly like the vin and serial.
Another use is in VE's. Most of the modules are security linked by a vin. Any second hand part could be installed without any security reprogramming realistically. Hook device in with new part and away you go. Security is also easy attacked.. Install a second component (BCM, PIM ect) and bend the security to the correct value. Security system is now completely eradicated. The security example is more of a 'black hat' kinda example, but still a method since without the stupid immob value.. components are about as useful as a brick.
This is just a 'proof of concept' since I will be using this tech to obtain various calibrations from tis2web for Holdens as well as other VE/VF modules. And same for the Fords. But really, are we in the era where we can actually make our own custom "modules", implement our own routines and inject custom information?
I probably cant express how excited I am with the thought I could add a "plug-n-play" device into a VE or VF (or fords!). Add in custom sensors or abiltiies, apply a custom CAN header to that device and you could be reading completely custom information using the standard CAN format like you would with a scantool!! Add in a boost sensor, obtain reading using module and read it out using a standard ELM! The options are endless.
I would have thought something like this would have already been available. But inevitably as parts and tech become cheaper and more readily available to the public, surely tuning companies would have thought this would occur? But I guess how do you prevent/protect against something like that? The best I can think is they update terms and conditions saying do not use in conjunction with XYZ device?
Thoughts!?
(Before I get harassed (or abused?) its all just "what if" scenario!)
so second hand is out of the question... until possibly now, Tazzi you F@%king legend 
It was more of a question whether tuning companies are prepared for devices like these to pop up in the industry. Eventually someones going to release a "ECU bender" or.. whatever they'll call it.
