Generic J2534 Diagnostic Software

[jakka]

I've started an open source project to create some cross-manufacturer diagnostic software for J2534 devices.

https://github.com/jakka351/GenericDiagnosticTool

Edit: latest release is available on the GitHub page and includes a DID/PID bruteforcer, Security Access bruteforcer, support for more interfaces like VCM2 and Tactrix, and a bunch of other stuff.

Just curious why it won't work with openport / gm mdi / mongoose / vcx nano etc? Isn't J2534 pass through all supposed to be the same? For example I'm building an app at the moment that so far is proven on the devices mentioned. Just curious, ain't knocking it.

Here's a wild idea for you. I call it Spoof Box. PC -> box -> ECM. China spec mass produce and sell it for a bargain at $100 with additional fee of $50 per ecm slot.
Program spoof box with ecm serial number, vin and whatever else. Must know byte offset as well, over time a database would build. When connected to a recovery ecm, spoof box firmware passes through all traffic except for the programmed details where they are intercepted and spoofed back to the connected software or to the ecm depending on the user configuration. The connected pc software / ecm will be none the wiser. It's a novel way to digitally preserve an aftermarket tune onto a recovery ecm in the unlikely event that the original ecm fails. Crazy enough that it might work.

I'm not entirely sure why other devices don't work with it yet, still trying to troubleshoot the issue.

Cool app (in the original post!) Why would not all interfaces work? There are differences in drivers / hardware / programs. J2534 is a standard but its a complicated standard / protocol and devices and device drivers are not certified against any test cases to be allowed to advertise as j2534 compatible. Thus they dont all behave exactly the same. For the spoof box idea, lets not hijack this thread, please start another one and keep this one on topic.

I haven't tried the app yet but I did try building the project and it seems to be missing the properties folder?
I'm sure I'm doing something wrong? lol

I've uploaded the missing folder, so you should be able to build it now.

Latest release and code is now on the GitHub page, project coming along nicely

What makes you think I give a fuck

What's your problem jakka. You should be ashamed and embarrassed by your reply.
