Saw this on Slashdot today -

Using On-Board Diagnostics (OBDII) sounded great to me, but the pricetags of systems like AutoTap Scanner are a bit much for my college budget to handle. Are there any free, open source solutions available? What do Slashdotters do to tinker and record the inner workings of their own vehicles?"


It's going to take a while to work through the responses, but it looks like there's several options out there. Maybe none are good, maybe they are.

A couple things I found that look promising -

EasyOBDII.com Free software download, Windows/Mac only.

USB/CAN adaptor A high quality dongle? The /. thread suggests dongles can be had for less than $30 on eBay.

DIYEFI.org Open Source engine management. No idea how far along they are.

edit - looking through some more -

A $45 OBDII dongle and basic code reading software. There's also a $13 OBDII extension cable


The PyDB2 package provides a Python DB API 2.0 interface to IBM's DB2 database management system. The package also includes various tools for working with DB2.

ELM327 USB Vehicle OBD-2 Scanner Tool - $30

ElmScan 5 Compact Scan Tool - $60
