I have been struggling with completing my E-Tune due to knock/detonation issues. I have already had the cyclinders compression tested and they are perfect. I do live in a very hot area and its constantly over 105 and I am on 91ACN gas. If anyone has any suggestions please let me know. Here is the last 3rd gear pull after my AOS/EGR install.

do you actually hear it knocking? i'm not sure it's knocking at all. as you load the engine your knock feedback tapers down and then eventually goes away, and it switches over to fine knock learning, could this be pointing to false knock? i know less about how these DI tunes work so take my words worth a grain of salt. your intake temps aren't exactly low, is your intake short ram? maybe try the stock box to get the temps down?

Yea I have the Mishi CAI. I have been leaning more and more to false knock. There have been some situation where I could just about time the knock event. However, when I get into WOT and see these kinds of numbers I start to lean more towards actual DET. I have done everything I can do to resolve the knock issues short of E85 and Meth injections lol. Is this something that can be tuned away?

but as you get farther into your loading, your knock actually goes down. at your highest load points you have small amounts of fine knock learning. you could throw some higher octane gas in to see what happens. get some race gas or equivelant and see if the knock feedback/learning goes away. i don't see DAM logged here, do the newer ECU's use DAM?

Yea I was thinking the same thing. In order to see if its just the quality of the gas I was gonna get some Octane booster. I know its not the best idea but I have really crappy gas in my area. 91 ACN :*(
