07 TSX A/T Knocking at WOT

[hirokichi1209]

Hello, I just got the Flashpro and uploaded the "tuned" calibration on the car. I did some datalogging, and I see the engine knocks on WOT mostly on cylinders 1 and 3, I don't hear it ping though but I am worried the knock control is at 100%. I have not touched the calibration parameters except for the fan temperatures. Valve lash has been adjusted recently.

I do have some knowledge of engine performance, but I am completely new to tuning.

I do see around the forums to retard timing, do I adjust on the blocks where the knocking is happening, or the whole collum?

Current mods are only an Injen SRI and a throttle body coolant bypass. I am always on 92 octane.

Any insight would be greatly appreciated!

Try reducing the timing in just the areas it is knocking.

I've been retarding the ignition timing by 1 degrees increments on the calibration according to the datalogs that I've been taking these past 2 days. Performance has not changed. So far the knocking on cylinder 1 has reduced significantly, but cylinder 3 has knock values of more than 5. Does the location of the knock sensor play a role in this as it is between cylinders 2 and 3?

It depends on if it is actual knock or something else that is being detected as knock.
