    Hey guys, I need a little help here. I'm currently in the process of getting tuned and I am on my 2nd revision map. Today I started to get fuel cut after loading the new map and I'm curious as to what is causing it but have next to no experience looking at logs (I tried to read the old guide from MSF many years ago and I just didn't make sense to me). Could someone take a look at my logs and try and make sense of what's happening? I've already emailed these logs to my tuner, I just wanted to know what I should be looking for to determine what's going on.

    The first log with FC in it is the log that was getting fuel cut. The other 3 logs were done after driving the car around a little bit longer (figured the car still needed a few more miles to adjust) and those pulls were fine, but then on the way home I got FC again while I wasn't logging.

    Thanks for the help!

    So another person helped me understand that the FC log is running super rich (A/F ratio) but then the next 3 logs after that were within spec. Why would I then get fc while driving slightly aggressively after the WOT4 log?
