S4 B5 -99 Sweden


« on: May 05, 2023, 08:44:26 AM »

Hi!

I'm thinking about installing a small minipc with a small 10" monitor and my FT232 cable mounted in my own obd port (connected to a direct k-line to ecu).
Would i be possible to make a live logging and interface like the maxxecu thru Me7logger or other logging?
Or maybe it's already someone who have done it?

My car is a S4 B5 pre-fl so i don't have canbus.

Yes you do. Not in the OBD socket but PTCAN is there.

And yes it can be easily done.

Easiest way is to use some app that can read raw CAN frames and has a visualization display.
There's a lot of those. Hook it up to the PTCAN, maybe enable some more messages in the software, and job done.

Of course not all parameters are there, if you want more parameters you will need to request them via K-Line.

Use the Arduino logger and post the variables on a display.  It's already done here, just needs tweaked.

Won't work on pre-fl because Arduino logger is facerolling sniffed commands to ECU without any clue behind them.
The bootrom is different, the addresses are different and there is no logic for that in Arduino logger.
