I'd really hate to spend anymore money on yet another cable, but I'm not sure there is much support for developers using the Tactrix as the forum http://forums.openecu.org/ looks pretty much dead.

Feel free to shoot me a message, support AT obdxpro.com, we support devs so can shoot across a OBDX Pro GT

bubba2533,

I can help you get rid of echoed messages but some debug log will be needed with gm mdi manager.
Typical install path of app
"Program Files\GM MDI Software\J2534 Configuration\J2534ConfigApp.exe"

With it we can see what exactly is assigned as flags to echoed messages and filter it on software level.

Ok, I have that ready to go if you have more information on what you need I can run it.

Will do!

Set it to log tactrix and just do some scripts in universal patcher with it, make sure messages are echoed.

Small log with echoed messages will be enough.

I’m not sure if I’m doing it correctly, but I’m not getting any logs.

before you connect with tactrix device open the app

Follow the screenshot and click apply Leave app opened.

There will be a file and path where log will be saved.

After that do some data logging or CAN script with universal patcher using tactrix device.


Log will be filled when you use the device.

Ok so I'm getting an error in UP when trying to do that.

Code: Select all

J2534 client initializing...
Initializing J2534 Device
J2534 client: Device initialization fail.
J2534 server: Device initialization failed

I can only guess it doesn`t like to be monitored. Not much we can do now.

[bubba2533]

That's disappointing. Luckily I'll be getting a OBDX Pro GT in the mail and I'll get back to testing!

We might get some debug data within Universal patcher, so it is still possible to get rid of it. I hope the echo is not from serial port settings.

I'm also getting an error in DrewTech:

The file is in that folder, and it works find when I disable the monitoring.
