Question - Is there anyway to use PcmLogger to listen in on VPW traffic? It would really help out alot if I am able to log communication between a Tech2 and a PCM.

No, PcmLogger is for logging Tuning parameters ...

If you want to monitor all of the messages on the VPW line, there are two approaches that I know of...

With an Arduino Mega2560 and a couple resistors (and optionally an RGB shield for blinky lights) you can use either of these:

But those just dump raw data to the serial port and it's up to you to copy/paste/save/figure it out.

JLValdez made an app specifically for that kind of thing, which requires an OBDX Pro interface.

I haven't used it yet but I plan to, it looks like a much better approach than what I've been doing with the Arduino.

Latest UniversalPatcher have basic functionality for this.
Logger -> Analyzer

You have a J2534 device, right?

How do I use it to record VPW data? I couldn't figure it out.

Not trying to push my own code too much, but have you tried my updated version? Seems to work switching between normal and 4x speeds as far as pcmhammer is concerned, haven't tried it with sps yet..

Start UniversalPatcher.exe
select Utilities -> Logger
Select "Settings" -tab, setup your device.
Select "Analyzer" tab and click "Start Analyzer"

But if you ask how hardware should be set up... I have no idea.

Sweet joukoy ...

It is possible to get it to produce the raw data in text form ??

Edit; When connecting it always responds with an 'Empty response' what is that ??
