Hey guys,

I notice EFICU helping a lot of people running into problems with the basemap. I am going to be 100% honest I’m looking for someone who could help me out as I see him doing, I have installed the MAF basemap and the first drive it went pretty good. Didn’t see much knock one time I got KR of 5* but it happened once and only got a total of 3 knocks on a 25 minute drive. Then, today I started my car all sounded good every seemed fine drove pretty good, I continue to get coffee all well not a single knock. Come back out from getting coffee run a cup down to my girlfriend and on my way home rolled into it a little in 3rd and boom got 3 knock count, 11* knock retard. Drove civil the rest of the way home after getting KR readings anytime throttle wasn’t steady. Came home reached out to some people they all told me I shouldn’t see that high of a KR and I’m not terrified to start my car.

Knock Count: 5
Knock Control: 4MIN 47MAX
Knock Retard: 0MIN 11MAX

Sorry for the book but that gives as much info as I can. And if someone can help I would be very very appreciative.

Did you piss off your girlfriend or get her the wrong coffee? Maybe she cursed the car while you were there. :)

The knock count, knock control, and then knock retard all work in unison as part of the equation to stop or reduce knock as best it can. If it is hearing a lot of noise but not recording it as knock, it may still raise the knock value to induce knock retard to stop knock it thinks may happen proactively. Or when it does record knock, then the knock control value will go up and pull timing of course. So it all works together.

Can you give us some context as to your setup, what octane fuel you run, and exactly which calibration you're running? Have you been datalogging or just watching the data on the Hondata App?

With some more context we can further discuss how to move forward and see what you might need. Either way it's all very straightforward, definitely nothing to worry about at this point in time.

EFICU!!! My man! Luckily the coffee was right, I do have two very small data logs but they are from the drive of last night where it seemed to be a little happier. Only catch they are on my friends laptop. I run 93 and 9/10 times it’s from a top tier station. I am running the MAF tune for a 14-15 Si. The data that scared me is unfortunately not logged. If it is easier I can message you on here(if that’s possible) my email address. Whichever works easier for you! Thank you tons in advance!

*ADDITION*

Car is stock. Literally lowered, drop in filter, 2.75”ID N1 cat back.

[EFICU]

I see. Without seeing where it's knocking we don't know where it's happening in the table really. With 93 though you shouldn't have too much knock, but every car is different.

Do you have any mods planned for the near future, is this your combination moving for a while?

Communications have to be done through the forum per the forums rules.

[codyFB6]

Understood. Sorry about that for saying about email. I only got a handful of knock counts but I reached out to a tuner and friends they all made me feel like seeing the knock retard at 11 it should be cause for concern. Like to the point of I’m scared to even drive long enough to datalog. Do you know if this is accurate? I can try to have my buddy email me the datalogs and maybe my brothers MacBook will at least let me upload them to here. I just don’t know what’s all in the datalog as my friend was the one on the laptop haha. I am playing with the idea of an intake and exhaust this summer but it’s my daily so I almost feel like I should just keep it as is.

Giving you as much info as possible in the meantime I know the knocks today occurred between 2800-4700 rpm as that’s what the pull was today in 3rd. The KR reading moves from zero anytime I add more than I’d say 20% throttle.

[EFICU]

No problem on the email thing. The knock retard is all an equation from the knock control value, knock ignition limit, and knock retard tables. At the point of 11* ignition being removed, the knock control value is probably very high so the ECU is trying to reduce or stop knock proactively because it thinks you're running low octane fuel. Not that you are necessarily, but wherever the knock is happening it most likely has too much timing for your car it sounds like. There is no one calibration out there that works perfectly on every 9th gen with the stock intake and exhaust. That's why we tune them based on what your car likes, not what someone else's cars likes. The basemaps from Hondata are a starting point, adjusting those are always recommended to get you the best tune possible and that is knock free.

Since you plan to add some mods soon, I can send you my basemap for a stock intake and exhaust car and we can see how it looks. We would need to do some datalogging and make adjustments, but that would make things easier to fine tune and get you off to a good start. Depending on where the knock is happening, my calibration has less timing than the file you have. So it would be a good start, especially in the rpm range you mention, but we need to datalog so I can make adjustments to the ignition and fuel.

Short of you having a mechanical issue, the knock is very easy to remove. So don't stress on it, it's all part of the process.

[codyFB6]

Heck yes man! My buddy will be by today or tomorrow with his laptop so I can upload it then and get you a data log. Any certain things during the log and for how long should I log?

[EFICU]

Okay, load this one up when you can and take it for a drive. For the datalogs, we need them to be around twenty minutes with stop and go type driving. On the drive, we need one wide open throttle (WOT) pull from 2500-7500 so we can watch for knock and work on WOT fueling.

On the drive, the knock control value starts high and then will come down over time. So if you see some knock retard don't stress, as it gets knock free the knock control value will come down and it will result in less ignition retard. So be patient, but take it for a spin and then post the datalog so I can look it over.

Awesome, will do! Thank you so much for your help I really appreciate it!

[EFICU]

You're welcome. Keep me in the loop on it all.

[codyFB6]

Hey EFICU,

I will be uploading tomorrow I wanted to ask if you think you’d have any time tomorrow with it being Sunday to look at the logs and make any small changes if need be? Just wanted to be courteous of your time, and if need be I can hold off on uploading that map and just go to stock till I can get my own laptop here in the upcoming days.

Thank you again,
Cody

[EFICU]

I've got time Cody, no problem. Just make a post here tomorrow when you're about to upload the calibration so I get the alert from Hondata. Then I'll be on the lookout for the datalog to follow after that. My end is easy, you guys have the burden of time with the datalogs so don't mind me.

[codyFB6]

Haha, I appreciate you big time man! Can’t wait to have this thing bumped up a little but still reliable haha.

[EFICU]

Yeah we should be able to get it pretty good. Once you add an intake or DP it will really open it up. But I've worked with a lot of guys with similar setups to what you have now and said the car was a blast. So they could be lying to me, but I don't think so. The main thing is having fun and being safe on the tune.

We'll see tomorrow.
