Default Stage 2 WRX (06) Datalog COBB

Hello,

Recently purchased and installed my COBB AP V2.

Was wondering if there was anything I should be aware of based on my datalog or some feedback.

https://docs.google.com/spreadsheet/...2lsVTh3dno4RGc
- Log was taken in 3rd gear from about 2k - 6k RPM

Current Setup:
Invidia v3 catless DP
apexi N1 CBE
COBB stage 2 OTS 91 oct

Ever since the DP install w/ AP
- I've noticed a ticking noise (did some research, some say its normal?) when stepping on the gas
- Not sure what it is, but flooring it in 2nd either feels smoother or slower. can't really tell (doesn't pull me back into the seat anymore)
- 3rd feels a lot stronger


Thank you

The car appears to be having some knock as you build boost. How many miles are on your car and how old are the plugs? How long ago was the intake filter replaced?

Hi Ian,

Current miles on the car is roughly 77k. I honestly have no idea how the old the plugs are and haven't checked the intake filter recently. I will check the filter in a bit and replace if needed. I bought the car at around 65k?

At the time or purchase and still now, I did not have much knowledge of cars in general and am learning something new by the day. They told me the 60k service was done for the vehicle but the purchase was at a Toyota dealership. I didn't know at the time that subarus require new sparks every 30k miles. So I didn't bother to ask. Fluids and else were all changed though.

Should I be greatly worried about the knock? I don't exactly know what it is. I'm getting the idea that there are more than one types of knock. Should I be driving under boost or not driving at all ATM?


These are two more datalogs done +/- an hour of the datalog posted in my first post.
https://docs.google.com/spreadsheet/...2l1ZUNLRG5YdUE
https://docs.google.com/spreadsheet/...Up6N2ppN2xoYUE

- I wasn't sure what knock you were talking about. I watched the askCOBB video and my guess is that it might be the feedback knock?
The guy the in video said I should be worried . And my first log has feedback knock but these two don't.


Thanks for your reply. Your help is greatly appreciated.
