Fg2 newbee question

[Yimmee]

here is the updated data. I Cant thank you enough. I took my friend out for dinner and she was like WTF lol.. i cant wait for the hybrid racing intake to come and then the headers. wonder how much of a difference it will feel after that. I meant to keep it NA and just work on bolt ons for now. I meant to ask what u drive by the way ?

[EFICU]

You're welcome, glad you're happy. That's cool your friend noticed a difference. The car will be an entirely different car with a proper tune and the HR and race header installed. Honestly you don't even recognize it as the same car from a performance standpoint. The intake and race header are the biggest change to the tune and allow for more performance. Watch, don't tell your friend you did those mods and a retune, then take her for a drive. She'll probably freak out.

That datalog looked great. Go ahead and make another when you can and we will see how it looks. If it looks just as good, we can probably call it good to go for now while you await the new parts.

lol i aint going to say anything to her and make her feel it.. here is the latest log. its a little longer this time but there was so many cops out today lol. anyways let me know your thoughts as always and thanks again.

[EFICU]

Honestly, you will be amazed at how different the car will be. First gear will be almost useless if you get on it from a dig or a roll. Unless you have some really good tires of course.

Was this datalog made with the same tank of gas as the last datalog, or did you fill up before this one?

[Yimmee]

I filled up the gas before logging again last night. Sorry was that bad ?

[EFICU]

Nope not at all. We haven't seen any knock, then all the sudden we had some in this most recent datalog. So I was interested to find out what changed, if anything. To know you filled up with new gas is what I was thinking. Go ahead and make another datalog when you can and we'll see how it looks.

[Yimmee]

Okay I will run one tomorrow. What are knocks by the way and is there anything I should worry about ? I’ve been driving it today and just don’t know if I should take it easy or should baby it lol

[EFICU]

Knock is basically pre-ignition or uneven fuel burn within the cylinder. Generally too much timing causes knock, but in your case we haven't had any knock the entire time, then all the sudden we get it after new gas is in the tank. It's entirely possible to get lower quality gas from time to time, that's why Honda builds the knock control system into the ECU to pull timing if needed in this case.

Here is a really good video from NGK to explain it better than I can. https://www.youtube.com/watch?v=4ZysyokEU60

It's not enough knock to cause an issue, we just want to make sure we're covering all our bases and making sure it's knock a trending thing. You want to remove knock that happens consistently. My curiosity was peaked simple because you haven't had any knock this whole time, then is comes out of nowhere. We'll see how it looks in the next one, then once you put new gas in again we'll double check it all again. Definitely don't panic right now though, it's nothing to panic about. It's all part of the process.

[Yimmee]

awesome thanks for explaining. so I thought I recorded the whole drive but i must have hit the stop log on my laptop so its a short clip. after i noticed it stopped recording i still had data log going and only had 1 knock when i finally was able to park. let me know if i need to run another one.

[Yimmee]

i was able to get another log. here is a longer one lol

[EFICU]

Yeah it looks good, the knock is mostly gone again. Go ahead and make another datalog when you go somewhere and I'll look for some trends to adjust based on that data. It's looking solid, just a couple areas I want to tighten up/nitpick.

[Yimmee]

here is 2 logs from today. lol so much hondas on the road just flashing me wanting to run one lol .

[Yimmee]

here is the newest log from today. I got about 16 knocks. i did run the car to empty last night before filling up with new gas that way its not mixed from two different gas stations just as a fyi. as always thanks for all your guidance and help :). let me know what you think

[EFICU]

Yeah most of the knock in the new one was from cruising in 6th gear on the highway it looked like. So do some more of that and we'll see how it looks. All the knock was in one small area, so that's a good thing.
