    Can't figure out why ve tune is getting richer each day.

    I thought I was pretty close the first day I logged from home to work (htw) and work to home (wth). They were all -1 -2. Then the next day, its -3, -4, then the next day its -4 -5. What is going on?

    If the LTFT's are between -7 & 0, that is a very good tune. I'm not sure which histogram is the LTFT? Do you have the LTFT map & rpm boundaries set up right for your camshaft & idle speed? It is better to post your scan file than using a Word Document.
