I'm gonna try and do some fine tuning here and I need to know what is the best gear to do atap runs. Also I read some past posts that mentioned only looking at certain fuel cells for different readings. What is the fuel cell and how can I tell what number I am reading in atap? One last question I will be using the older dos version of atap and I noticed that on one of my stock runs my ltrims at crusing was in the negative levels around the -3 to -4, it seems that most report an above 0 level so this seems strange to me,,, is this because it is the old dos version,, thanks in advance
