All you electronics nerds out there...
Boss just handed me this months Silicon Chip magazine... make your own OBD tool.. can even buy the kit complete and put it together yourself
http://www.siliconchip.com.au/cms/A_111859/article.htmlOBDII Interpreter: Main Features
• Enables checking for diagnostic trouble codes
• Clears trouble codes and Malfuntioning Indicator Lamp (MIL)
• Shows real-time data
• Extra features are software dependent
• Interpreter interfaces between the vehicle’s OBDII port and a computer
• Serial or USB connection (via an adaptor) to computer
• Power for the OBDII Interpreter obtained via the vehicle’s OBDII port
• Works with CAN, ISO, KPW, PWM and VPW protocols

Sure, we dont have to worry about viking raids or scurvy anymore, but instead we make a daily routine of sitting in flimsy, fibreglass (or metal) boxes full of gasoline which are propelled in opposing directions on the freeway at velocities matching that of low flying aircraft.
This is a roundabout way of saying that cars are dangerous....
How much is the kit?
Track Times: Phillip Island - 1:59.4027, Calder Park - 1:08.8142, Winton 3km - 1:40.7810, Sandown - 1:29.6000, Haunted Hills - 62.55, 1/4 Mile - 13.736
do they do one for an OBD I ?
2013 Ford Focus ST
Calibra - The only car that will institutionalise you and send you broke in the mean time
Remember that most opels are not fully iso compliant (hence the popularity of opcom)
My elm based one (im sure the SC project will be based on an elm interface or similiar) has limited functionality on the astras/veccy, although works well on most jap cars (except the mrs suzuki dammit!)
Good project, although i wonder how many non technical ppl will fry their ecu's trying to get it working
im gunna make one anyway and see how i go... chip is ELM327 btw(not the chinese knockoff ones the keep spitting up errors etc)
the magazine has the info on making an OBDI one aswell but couldnt find it on the net, not sure how much the kit is worth but ill let u all know

the elm327 chip is pretty nice
especially nice is that the communication protocol to the chip is well documented on the manufacturers website. you just need to send/receive ASCII strings to it and it'll tell you anything you need. easy stuff, i wrote a custom app to record acceleration runs and make graphs of sensor values
the only thing i dislike about it is the time needed between requests to the ECU. with my Barina you won't get responses to requests at more than 5Hz - each request only gives you the value of a single sensor at a time as well!
btw how much is the kit? because you know you can buy premade ones with a genuine ELM327 for about $100 right
The Silicon Chip "design" is nothing to get excited about .. and I use the word design very loosely.
They have taken the reference design from the ELM327 data sheet, added a MAX232 driver for the serial port, designed a fairly crude PCB layout, and re-drew the schematic to look a little nicer. Even the component designators have been copied from the data sheet.
