I already check the FAQ but some of the threads don't completely answer all your questions. I just want to know if our car computers will eventually work it's way around the vaf-c? Is there some sort of way to keep this from happening? Or is it something that you just reset your ecu? Every so often?

I heard that the ecu will adjust settings over a few weeks. That after you tuned your car that in a few weeks you lose all that and some because the ecu trying to adjust the a/f.
