Was checking up to see how my tune was holding up with the recent colder weather and have found that I seem to be getting consistently more knock as well as the fuel pump running at a higher duty cycle.
Previously the fuel pump would peak at around 95% at peak boost, now even after reducing the max air charge I still seem to flirt with 100%.

I'm assuming since its colder the air is more dense and it is adding more fuel to compensate, but for equivalent air charge values it uses more fuel.
Is it possibly a sensor issue or is this normal behavior?

Additionally is it normal for these cars to have a strong smell of gas in the oil?
I know Honda has had issues with oil dilution in their turbo civic and crv models, but I haven't seen any reports of issues with these engines yet.

Also on a different topic I am running a duplicated ECU, if I were to take the car in for services should I flash the ECU with a stock tune or reinstall the original ECU? Would installing the original ECU throw a red flag for them?

Desperate for help at this point!!!

I have a 2015 9th gen with a stock k24. Skunk 2 CAI and rear hasport motor mount.
I am getting knocks from 5500-6000rpm mostly from 3rd gear and above.
I have had this issue since last year when going through with an etune and have then had the car dyno tuned and i am still experiencing the same issue.

Including the current tune and a log from a good day where the knock was not as heavy

If you want to start your own thread in the 9th gen FlashPro forum I can try to help you with it. This isn't the right thread for your car.

From what I see, the knock is all happening in one area. We can try to pull some timing in that area and have you retest. I'm also curious why they have your tune so rich, but we can discuss that in your thread once you make it. Post a thread in here viewforum.php?f=44 , which you can just copy and paste this post in your new thread.
