Yea I understand its only data coming out of the ecm, and not a way to tune. But I still think it would be nice to be able to datalog, even though I cant tune it. It might give more insight into possiable intermittent problems that can be tricky to track down. With 270K on all the original sensors (except o2 and injectors) I am just waiting for something to go out.

So if the files are not out there for public use, how were the GM ones obtained?
