Found a way to very accurately diagnose our cars
So, I just figured out a way to take all of the guesswork and trial and error out of fixing any car with OBDII and would like to share it with the community. After we get this going members of the community will never undergo unnecessary repairs again. Explanation:
I'm a PhD student in political science, which entails a great deal more statistics and calculus than one would think. We use fancy statistical software which with the proper training is capable of making incredible inferences about complex questions about human interaction. Using the same methods to make inferences about mechanics is very, very straightfoward. My diagnostic saves data in excel format, which I imported into Stata. What I found in 30 seconds would have normally have taken a professional a decent little bit of looking at outputs in real time (if they actually went so far to do so, which I have never heard of a mechanic doing)
The implication is that by logging data and subjecting it to processes similar to those used in the social sciences there is no longer a reliance of guessing what vague DTCs could mean and then eyeballing real time outputs. It is possible to hold factors constant (such as driving conditions or region of the world) which takes all of the guesswork out of diagnosis. By comparing a logs on cars operating properly with that of one that is running rough or making a sound, within a minute we can say "this is exactly what is different, this is what it is causing". Further, with a database of what members' solutions were we can go one step further and say "this is the fix".
(edit) When I originally posted this it was just a fun little side project, but in the past few hours some colleagues convinced me to pursue a patent on a system a little more advanced, so I have changed the post accordingly. However, if anybody would like me to do this for them it pretty straightforward so I am more than happy to do so for free and get back to you on the results. Benzworld has helped me out so much, it would be pretty s***y of me not to pay that forward. All that is necessary is to save the log in some sort of excel or csv format. If we can convince somebody else with the same engine to do the same I can accurately pinpoint what is happening.

Reason: concept changed, had to walk back a few things
