Have spent countless hours and research and I basically don't wanna grenade my engine.. I have a bone stock 2011 civic si besides a drop in filter. I got the Flashpro just to delete the revhang. Using the stock tuned calibration I have noticed a bit of knocks on data logs. Anyone able to take a look at my data log and point me in the direction of getting the knocks reduced? Calibration and data log attached:

I plan to drive that car as is for a few months, possibly upgrade to a hybrid racing intake down the road.

Any help or insight is appreciated. Thanks !!

Car has 170k miles, maintenance has been very well upkept. 93 octane gas.

Have you tried reducing the timing in the areas you are getting knock?

I have not done anything. Wasnt sure to start with fuels or ignition. Just steady doing research

If there is a lot of knock I would work on that first.

I ended up getting the Hybrid racing intake for a very low price. Installed and found a calibration that didn't bring much knock and drove super smooth. I tried the auto tune function to try and get the fueling closer for my car. In a On a 45 min drive I didn't see many knocks. My first data log I attached has zero knocks I believe. The 2nd I noticed a few near the end of the log. maybe drop the ign a degree in that part? Should I make a new thread as I have the intake now ?

Stick to this thread.

Thanks I have just been rocking that last calibration. I’m not too sure on how to adjust the timing pinpointed to my knock

not looking so good. i dont want to drive my car anymore until the knocks can be addressed. Im not sure who i can reach out to to pay for tune or to adjust the knocks out. thanks

I looked over the file and it seems that in areas where knock is located the car is running lean. I would address the fuel then reduce timing if the knock does not go away.

Let me know if you need something to make the car run safe or a full E-Tune.

Hey Ed! I'm having the same exact issue, and I had messaged you on Instagram. Please take a look when you can.

Thanks.
