I have wanted to use an OBD app for a while, but my car is too old to have one. :)

  Do it yourself! There are plenty of folks who have instrumented their old cars, both for curiosity's sake and to improve them. I'm looking at adding a sequential fuel injection system to my vehicle a la www.diyefi.org among others, instrumentation would be much simpler. This solution is much more difficult than the post, but can be very rewarding.
