Hi. my "case" is an aluminuim frame, the same used for the subaru lilliput kit on mp3carstore.
But this week end i will move my computer to the trunk. It was not a really good idea, my fan blade sometimes touch something in the dash when the car jump on a road hole (and we have many hole in road here in canada). And each time i need to do some modification to my computer i need the remove all the dash.
For ODB2, i use the pcmscan kit, software & odbreader integrated in RR.
It's a cool gadget, but i tried it on the drag track. but the data rate is too low to get real interresting data.
So cool for getting moving things on screen, but not for real data logging.
Still working on that to find if it's my configuration or the way odb2 work.
