I am learning how to work on my fuel trims. Currently I am looking at the LTFT special function in the VCM Scanner. My trims are in the 10's most of the time. However, when i turn on the LTFT relarn, the trims quickly get better. The more i drive with the relearn on, the better it gets. When i disable the relearn button, the trims immediately get worse. You would think that turning on relearn would change help the computer adjust the tables and save the changes. What am i missing?
