    Looks like you flatlined 4th gear timing hurting your trap speeds.

    Are those IAT's the norm for drag racing? He almost hits 160*F by the end of 4th.

    You can't fix it if you don't know what causes it! FYI I have the same problem along with many other auto N54s. Shift above 6500 rpms going into 4th. Works for me.

    Looks like your ambients were really high...your IATs at the beginning start out at around 140F, which is already really high, and end up at 160F...strongly suggest running meth, even just 50/50 and a small nozzle to keep those IATs in line...

    Post up your CSV instead next time...i really don't care much about graphs

    I don't know if i'm getting my colors confused, but requested and actual load are way off. Could be due to capping boost, but boost does seem low compared to other 2+ logs I've seen. AND, AFR in 3rd or 4th is a little high for half that gear.

    I have a automatic I also drive an hour to the track and go straight to the staging area and start my runs, would this be why the IAT's are so high?

    DZ what is CSV? If I have i will post or send to you.

    CSV = comma separated values

    Your Cobb AP datalog files are saved in this format with a .csv extension on the file name. Basically post the files that you take off the AP to your machine instead of having to plot the graphs.
