I am a long time lurker, with a 1998 v70 T5 AT. I have a MS in Mechanical Engineering and a MS in Computer Science. I have done research focusing on intelligent algorithms for vehicle control. While I definitely don't have the low-level programming chops that some of the major contributors have, I'm hoping to contribute to this awesome community as I tune my Volvo.
I love the effort that has gone into the logging solution that currently exists, but I've been working on an open-source logging device based on a RPi. I'm wanting to tie in some analog voltages with the OBDII logs without modifying the ECU and without dragging my laptop around to log. This will (hopefully) facilitate easy log gathering and the ability to fine-tune a map based on daily driving over time. Hopefully the attached image gets the point across -- an effective "boost curve" created over many daily drives for the tune I'm working on.
My ultimate goal is to algorithmically optimize my tune (and hopefully anyone else's) based on these logs.
I currently have one major problem -- How do I get the OBDII command equivalent of the logging parameters in the ADX files?
If it would be useful, here are the docs for creating custom commands for the OBDII library I'm using: http://python-obd.readthedocs.io/en/latest/Custom Commands/
