  1. Hey all, had a wild holiday season. I travel a lot for work and have a toddler and pregnant wife, so I was consumed by family duties for the past month or so... one person has spoken for the CAI, RIP Kit, Jpipe, and TCV. I’ll update either way if that works out or falls through. Everything else is still available. Shoot me a DM with any questions or offers
  2. Unfortunately, the motor went on my v70. It was a fun car while it lasted, but the body and interior were not in amazing shape, so it didn’t seem worth saving her. Here’s the parts list. Will definitely offer discounts for bundling: IPD exhaust for straight flange turbo (extra bung for wideband in DP, mild hanger modification because it was rattling against the chassis) - $450 IPD skid plate - $100 SOLD: Snabb RIP kit - $125~ SOLD: Snabb fresh air pipe "j-pipe" - $75 SOLD: IPD CAI kit - $75 SOLD: IPD turbo control valve - $35 IPD MSD ignition coil kit - $60 IPD Stainless brake lines (front sightly used, rear never installed) - $100 Big brake brackets and near new front calipers with Akebono pads - $100 TSW Nurburgring wheels with tires 18x8 ET40 - $1000 3rd row seat (tan) - $200
  3. Cool, didn't know about the D2 protocol -- I was mainly referring to the custom logging that has been built as a part of the Tuners Rejoice body of work. I've visited the wiki in the link many times, and am familiar with that specific page -- was wondering if there was more information about how I could write my own software that logs from the ECU (instead of Tuner Pro). I'm definitely willing to hook up the Vag-Com cable and start sending serial commands then try to interpret them by looking at the ADX file, but I was wondering if there were more specific instructions/documentation anywhere. i.e. How to parse the "35-byte delimited frame" that will come back from the logging routine?
  4. @gdog, that's interesting -- I didn't know there was a separate protocol in the logging routine... Is there any documentation of the serial protocol for the logging routine? While it is not the best path forward, I often work with the idea of finding truth in noisy (in this case the OBDII) measurements. Might be an interesting exercise to try to make those more useful for the generic case where some awesome hackers haven't engineered a separate logging protocol ;)
  5. Hello all, 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/
