Uhhhh YEA! Lol... I keep up with the California special crowd killers(460hp).... until about 95mph .... Don't worry man, I freaked out when first tuning it... and even felt bad.... but I have been tuned for over a month and no abnormal issues. If you are worried about blowing it up, get the K-TUNE v2 so you can watch your knock control... ,49-.59 is a good range. it should stay at .49 though. If you get knock counts then your fuel grade may not be all that great with the tune you choose.

Just keep this in mind, the engine is rated for 20.3psi and is guaranteed to operate normally within those ranges for the most part depending on your fuel and maintenance. The extra 3psi is not much of a risk if you look at it like that.
Thank you earlier I was wondering if my knock count was okay you just basically answered my question

**IMPORTANT EDIT**

DO NOT USE OCTANE BOOSTERS!

Ignore anything good I said about OCTANE BOOSTERS. I have tried several different types and every one of them end up causing my knock CONTROL ("K.CON") to shoot up after a while. Right before that happened though, my car stuttered, and pinged.😬 I never jump on the throttle instantly anymore, so who knows what would have happened if I did WOT when this happened.

***BEFORE EDIT -- BELOW***
You are very welcome, beware though, unless you get it to rest at .49, I have seen it go back up on its own. You may try giving it some 25%-35% throttle pulls (8ish PSI) to 4k rpms for about 3-5 minutes, and it will go down and stay down most likely. Its very random when it happens but I have had it go back up as far .65 in just a few seconds for no reason what so ever... On the other note, I put in some octane booster a while back (STP OCTANE BOOSTER in the orange bottle) and it caused a crap ton of knocking, shuddering/misfiring ... Today, I put in some LUCAS octane booster, and it actually lowered my knock count by 75% ish. An example of how many knock counts I would have at 93 octane would be roughly 20-25 in a 20-30 minute period(I know its pretty much harmless at this low number. but if its detected and can be corrected, why not?)... Tonight I had roughly 6-10 in a two hour period. If you choose to do this, use it as instructed on the bottle. more octane booster doesn't always mean better lol. (All of this was done on the Starter tune "Base/23.5/no rev-hang/responsive throttle 1 and 3970k-4000k 2step)

Good luck man!

**EDIT** OCTANE BOOSTER IS NOT RECOMMENDED

I'm pretty sure KTuner doesn't recommend octane boosters. Hopefully JR can chime in.

See thats what confuses me.. i see just as equal facts on both ends about wether or not I should use it. Dont get me wrong, I did NOT feel a performance change what so ever, but it did lower the knock count significantly so idk. Im on the fence about it, especially if you guys dont recommend it.

I’ve noticed it only got knock during normal driving ,,,, under wide open throttle no knock count at all. I was using stop n shop 93 during all of this which isn’t my normal gas Choice normally I only do shell or Mobil sometimes citgo, Lucas makes good stuff, I’ve tried one octane booster when I first got the car but during that time I didn’t have it connected to a lap top. But yesterday like I was saying I got 3 knock count driving around for maybe 45 min ? And that was not under WOT

Keep in mind that on this platform, a small amount of knock counts isn't anything to worry about. Keeping an eye on K. Control is more important.

What are some numbers to look out for? 0.49 is normal right but how high would it have to be to cause some actual concern

There are many things that contribute to high knock control. Knock control is designed to go up and down. It's actually a safety measure.

If you are pinned at 0.9 - 1.0 and above, constantly, that would be something to look at.

On the topic of octane boosters, many tuners don't recommend octane boosters. And for good reason.

I totally agree, I had a bad experience tonight with the LUCAS I spoke so highly about. NEVER EVER AGAIN WILL I EVER use a booster again. I got some spudder/missfire again today. Yesterday, I had ZERO issues with it... I thought it was a sure thing after the good run I had. I actually gave it away to someone with no turbo. I will revise/edit my previous comment about it. I highly recommend staying away from it.

That is perfectly fine, Its actually very random, and normal. I have seen 1, or 2 knocks in an hour, or even 25 in an hour. Like he said above, its nothing to worry about. Its more about the knock CONTROL ("K.CON") that needs to be watched. Like I read somewhere above, if you get a bunch of knock COUNTS (K.COUNT") within an hour, you likely have a bad tune, or some other underlining issue. ("Example; 100 with in an hour or even 50+ with in an hour maybe") <<<I could be wrong about that, please someone correct me if I am.

I know that normal seems to be about 10-20 in an hour. You are right about the driving normal part. To lower the knock CONTROL ("K.CON") I always boost up to 5-8 psi from 3-4k RPMS from 2nd gear and above when it goes up to lower the knock CONTROL ("K.CON") back down to 0.49. Today, I had it report .88 because of this stupid octane booster I used to counter the knock COUNT ("K.COUNT"). BAD IDEA!!! Don't use boosters, it's just not worth it. When I experienced the .88, the car stuttered and pinged at me a couple of times, it scared the crap out of me! The weird thing is, I was just doing a normal boost creep to 12-14 psi for "funzies". I have to say that I am very lucky I that I didn't hurt the engine. Everything seems to be fine. There isn't any abnormal engine noises, or performance issues. 🙏

So I just reflashed back to stock factory take a look at these numbers or k count I should say

It looks exactly like when I re flash stock. No worries, Just make a few fulls with no more than 4-6 psi from 3-4k and it will start to lower. You do need to get it lowered in to the .49-.59

Assume it will take an hour to get it down.. it did for me.

Guys, keep in mind that an elevated knock control number is normal in certain situations. The higher knock control is there to protect the engine. Seeing .6 or .7 after some hard pulls is no biggie. Totally expected as long as it is slowly dropping down after some milder driving.

On the other hand if you are consistently seeing high numbers using say, 93 octane, you could be dealing with a bad batch of gas, for example.

Well it's been a couple of weeks since anyone added a new survey. I know we have thousands of tuned CivicX's out there so that's not the issue.

Maybe people don't realize this is an ongoing thing and this database helps the community's tuning knowledge base?

Anyway, if you're tuned take the couple minutes to fill out a survey. Thanks.

Might need to post a link every now and then in the general 10th gen and SI forums as I think it's mainly that the average forum user doesnt stray into this technical section unless they have an issue.
