Looking over your tune and logs, I notice a couple of things. First thing to keep in mind, is that we cannot see your wideband reading purely just because we do not have your interface with us. So we have to take your word on it that you say it is going lean. With that being said, here are some things I noticed, that you could pay some attention to:
- Match both of your high and low octane tables. We trust you as an auto enthusiast that you will put the highest grade fuel in your car (91-93) every time you run it. The "fail safe" for a bad batch of fuel will be the safety margin built in to your spark tables, and your knock sensors functioning correctly.
- Your IAT spark table needs to be changed. You have POSITIVE numbers in the table in high IAT areas. This is backwards, you need NEGATIVE numbers in this table. There is not a SINGLE table in hp tuners that is "Subtractive". Tables can only be additive or something else. So in your case right now when you reach high IATs, your car ADDS timing. Exactly the opposite of what should happen.
- Disable your Long term fuel trims to aide in your tuning. You wouldn't want some random (and innaccurate) fuel trim messing with your tuning. That will throw you for a loop and make it much more difficult to tune.
- Might as well raise your speed limiter to 255. I mean, you want your car to trap over 160mph don't you?
- Change your fan temps. Especially on a turbo car, you want the car to be running as cool as it possibly can be. I put the Fan on temp 10* above my thermostat value, and fan off to 5* above the thermostat value. (For example on a 160* thermostat: On= 170*, off= 165*) This will give your car a much great RESERVE of temperature if it ever encounters a situation that would cause it to get hot. (Like a long and steep hill maybe)
Try that stuff out.
