Made a little bit better video. Logging 66 params at around 50hz. You toggle the cruise control switch position to enable actual logging to a .csv file, otherwise just live viewing the data.

Mode 22 logging isn't quite as fast or advanced, but it will work on all ECUs. Similar to how some folks bought ecutek dongles to get logging for their UM cars or whatever. The dongle you need for this is called a Macchina A0 (or DIY an esp32 dongle) and is $70.

I recently jumped on the OpenSauce using both VW_Flash and the phone app SimosTools to flash my GSW before I sold it and my new S3. I think they best thing about this open source movement is the community, which continues to grow and is full of a bunch of really knowledgeable and helpful people. If you're wanting to save a bunch of money on a tune and do it yourself, learning along the way, I can't recommend it enough.

unfortunately I am not a very Tec savvy person so all of this discussion is miles over my head but i would just like to commend the guys involved for getting something of the magnitude up and running. I recently stumbled onto this because I just picked up an alltrack as a daily and I want to run a small hydrid on MPI but Chris (tapp) doesn't seem to want to do mpi for the 1.8s. Thumbs up!!

You could hit up @joedubs, he has a GSW 4mo with MPI and a DBV2. The community is really cool with helping you learn the ECU and the tuning process.

That's correct.

There's also a better CAN interface for the pi by a company called seeedStudio. It's based on an updated chip. Unfortunately, it doesn't have the same fit/finish/form factor as the PiCan though.

Fwiw, I'm using a piCan3 for all my headless logging, and most of my flashing. seeedStudio board I'm using for my bench setup

The tactrix openport also works great, is super fast, and is the closest you'll get to existing "laptop based" logging and flashing solutions.

HPTuners isn't open source. We can flash over their software to add better logging and open features, but realize you're still playing in their sandbox if that's the direction you go.
Is that the pinout in the picture to un lock the ecu? or is that just what's necessary to do a general flash. I am trying to figure out how to unlock the ecu at this point. I also have a APR 91 tune on my ecu. There is no way to preserve it or back up the Simos 18 due to the programming and VR reading? I was able to read the ECU data with tactrix now I just need to know how to un lock it

Simos 12.2, slightly different but should work. You'll need to use the CLI version currently but all info/instructions to unlock on VW Flash GitHub. Make sure you install 32 bit version of python to work with openport.

Reading ECU directly with Tactrix isn't possible, write only.
