I recently took my 1996 SSEi to the dealer for a relatively minor repair, and when they hooked up their scanner they came up with all sorts of codes indicating problems that I wasn't even aware of. It pointed to weakness in the ignition module and the crankshaft position sensor, which they replaced. The point is: I would have preferred to know this myself and not be driving a time bomb.
What'* the best way to uncover not just the ODB II, but all the enhanced diagnostic info (and more, if there is such a thing)? I'm thinking something that I hook up to a laptop, like the autotap:
There seem to be a lot of these types of diagnostic softwares out there, so maybe there'* something better or cheaper I should consider. Mostly, I want to know if there are pending problems, and if so what they are. Also, it would be nice to capture baseline performance data so that I can compare over time to see what parts might be failing before they actually generate codes. Is there anything that does this in an easy-to-use package? I hear some of these things even compute MPG, but I'm not sure how accurate they are. If they are accurate, then it would be good to measure this (instantaneous as well as average), so that I can perhaps modify my driving habits accordingly. Any strong recommendations?
