Evesdropping Software

[darkman5001]

I am looking for a program that will allow me to evesdrop on the communication between a GM PCM and a Tech2, and I want to record the entire conversation. I need to be able to see the commands sent, seed/key exchanges etc. Does anyone know of a program that will accomplish this?

It seems that all the loggers in that book run on Linex. I need one that will run with windows.

it may work with WSL? There's tons of can bus loggers out there. I think ironduke may have posted one he built here somewhere

Pretty sure he is looking for VPW logging ...

Thats the first question, what protocol are you trying to log? Many many different protocols with different solutions available, and are usually somewhat homebrew flavored. And there are many different limitations from different approaches. What are you expecting to get from this?

I am looking to see a log of debugging data like PCM Hammer shows while it is reading a PCM. I am looking to try to program a PCM with a GM Tech2 and then evesdrop on the communication as it happens. My goal is to learn the seed/key and kernel information.

irondukes program works very well for high and low speed can and VPW

What hardware do you have to use for monitoring the bus??

Can be something as simple as an elm327 using termite and using atma...
Can get a lot more involved with software that breaks down the messages as they come in, arranges them for you and identifies modules,messages,etc.. I do not have any of that, rolled my own and break it down by hand.. Mine needs to use a J2534 device though. I think if you had one of those you wouldn't be using a tech2 to program though..

I am using a J2534 to monitor the tech2 and PCM communicate. Just need a program that can use J2534 to do it.
