As for the Logging Trigger I use the defogger switch (rear), but you can use whatever you want. I tried CAN BUS at first but the logs never worked. They say you can find the ECU ID from within RomRaider Logger I actually didn't look there I found it in LearningView up at the top left, if its in RR Logger great, if not check the LearningView. I think you want to use logg_STD_EN_v247 which is what I used since I'm in the US. If you want to rename this you can select Save Profile As. Set the parameters you would like to log using the checkbox. Open up RomRaider Logger, you should be connected to your car at this point I believe (sorry if I miss anything). To generate this, go out to your car and connect your usb cable from the tactrix (plugged into the car of course) to your laptop. Just an FYI, the RomRaider profile you need for this website should be your profile.xml in your RomRaider folder within Program Files on your computer.
This website will allow you to generate the logcfg.txt that you need to place on your micro sd card that goes inside the tactrix unit. I think this is what you are looking for, I could be mistaken since my car is an 08 but I use a tactrix as well.
