Default Ap Log for 2011 WRX - Stage 1, 93 - CYLINDER KNOCK - PLEASE HELP..........

Been running stage 1, 93 octane on my new 2011 wrx for about 2 weeks - has about 700 miles on it. I did my first real pull for data today - started recording from 0-80 mph. Ran 2nd and 3rd gear from 2,000 rpm to 6,000 rpm with the pedal all the way to the floor twice. There is some basic driving around between each pull and after both pulls.

I have been posting all over and can't get any one to take a look and offer some thoughts on my readings. Im a noob definitely, and want to make sure that things look right with the car - I don't want to hurt it since its so new.

I posted the spreadsheet to google docs spreadsheets - please review - any assistance is much appreciated:

No break in for you, not even one oil change? If you develop any serious engine problem, it will be out of your pocket. Amusing that you mention: "don't want to hurt it since its so new" and yet you push a new engine 100% still on factory oil.

Thats not much Knock as the sum reads 3... Break in your engine before you start doing hardcore stuff.

Aside from this, I highly suggest you log LESS data.

Critical Stuff =
Engine Speed
Inj. Duty Cycle
Fuel Pump Duty
Throttle Position
Wastegate Duty
Boost Target
Calculated Load
Coolant Temp
Knock Sum
LM1-A/F Ratio *IF YOU HAVE A WIDEBAND, I use a MTX-L from Innovate to log this*

If your Injector Duty gets above 90% its time for new ones that are rated higher, other than that, I highly suggest you go to EFI 101 from EFI University. Will teach you a lot.
