Why is it that my tune drifts? I work for a while, get everything dialed in to where logs and Learning Views are clean for several weeks, and then ignore the tune for a while. I pull a Learning View a few months later, and IAM has dropped and learned AFR is out greater than 5%. This has happened several times. It is like I need to get a new tune every six months.
