Hi,

I just wanted to confirm that for my ECU that the "Disable rev hang" option is there as that is the main reason I'm buying this.

My ECU number does fall within supported ECUs but it is under international ... even though I live in NA lol 37820-5BA-C11 through C17 (I have C14)

I've seen videos of the option being there for the k20c2 but with what looks like an American/ NA ECU.

Also will running 87 cause knock with the tune as the website recommends 91.

Any help would be greatly appreciated.

It does.

Sorry, but does the "it does" apply to the knocking at 87 octane?

You wanted to confirm that it has the feature. It does.

See recommendation for octane right on the application page, as you mentioned. That's all we're going to recommend, hence the recommendation.
