Newb needs help with first log

[Jiggalude]

Here is my first log. I'm having a hell of a time trying to get this car running correctly, and unfortunately I really don't know what I'm looking at in this log. Help is very much appreciated. Car is stock except for a big FMIC. I have a wideband. Another issue that I'm having is when I pump the brakes the car goes lean as well. I'm starting to think it's not a boost leak and its tied to something else.

Can anyone help me? It looks to me like the timing is out of whack. Also, why would the car go lean when I pump the brakes? I even when as far as to pull the vacuum hose off the intake manifold going to the brake master cylinder and capped it and it still goes lean when I pump the brake pedal.

First thing you need to do is log combined fuel trim, isc position, maf raw, learned idle adjustment. then fill out your profile completely all the way to injector size and everything you can think of. your timing looked fine at idle but the tps voltage needs to be adjusted. make sure you have no boost leaks. and check out this link, it'll help you to get a handle on it. YouTube - Tuning 101 - tuning with the car off
and this one YouTube - Tuning 102 - Idle Tuning then go here and watch the demos created by the guys at ecm tuning ECMTuning, Inc. . then post up another log and you will probably get some more help.

Your o2 sensor is not cycling at idle = it's stuck in open loop.

Yea I noticed that too. Right now I just can't pin point the problem of my car going lean when I hit the brakes. Could a bad battery be the cause of it? I did notice that when I turn my headlights on that it will actually lean the car out also.
