Knock at WOT

{B3601} should match the fuel you are using.
Air fuel ratio comparison
E10 = 14.13AFR
Changing {B3601} will automatically change {B3605} & {B3618} as they are in EQ
and are based off {B3601}.

TR just reduces timing to prevent knock... it doesn't cause KR to happen, and it doesn't use KR to reduce timing...

The value you see for the KR pid is in response to knock/noise being detected by the knock sensors... the PCM determines how intense it is and sets KR which is subtracted from the final spark advance (i.e. SPARKADV reduces by KR amount).

Thanks for explaining that to me. Do you have any idea what could be causing the injector duty cycle to be at 85-90% in these log files?

I'm thinking I will change the PE value from .80 to .89. Do you think that would be good once I verify that the commanded AF is near the actual AF?

I wouldn't lean out PE unless you know what AFR actually is.
Getting LTFTs closer to 0% is something you can do w/o a WBO2.
They should not be positive during PE.

Alright I'll work on that first, thanks.

Edit: After reading a thread on E10 Fuel, I agree and think this is having some impact on my LTFTs.

Epox4life, did you get this problem rectified? If so, what was the fix?

[Dragframe]

wow didn't know the stock stuff was that off!

Never figured it out, ended up trading the car in just because I needed something more practical for a daily driver.

The knock would show more times than others for no apparent reason, it might have been due to 98's having inferior knock sensors.
