2012 Honda civic si knocks

[EFICU]

Gotcha. Yes, all of the datalogs we need the twenty minutes of driving with one WOT pull in third. We will be adjusting the WOT fueling and part throttle fueling in all revisions, so all the datalogs will include the same style driving.

so u need 20 not 12 danmn knew i was missing something

[EFICU]

No problem. Twenty minutes gives us a better average. We just don't want five minute datalogs is all. 15-20 minutes is fine.

Here is the next one for you. We are now on the 30* cam and vtec will be at 3800. I will start moving vtec around in the next few revisions to tune around the vtec engagement point.

[EFICU]

What about a misfire?

[AGP7827]

[AGP7827]

i really dk why i be having misfires in all 4 but i think it must be my coils i have to change it start to do that I believe after i change my sparkplugs but thats y i have misfire dict off til i know whats the issue

[EFICU]

Okay. So you want misifre detection turned off for now?

[AGP7827]

yeah but it really wasnt doint it til the last datalog but for mosly yes to avoid issues

[EFICU]

Okay. I didn't see anything in the first two datalogs, but it was showing the misfires in your old tune before we started?

I turned off misfire detection for you. You don't have an aftermarket clutch and flywheel do you?

Here is the next one or you. Still the 30* cam but with vtec at 5500 now.

[AGP7827]

its a stage one exedy

[EFICU]

That is part of the issue then. Aftermarket clutch and flywheels cause the misfire detection issue on 9th gens.

[AGP7827]

so best to get oem honda

[EFICU]

Not necessarily. You just have to turn off misfire detection on 9th gens. It’s very common if you google it. We should be good to go now. If you are worried about it being turned off, then yeah you would need to go back to the oem clutch and flywheel if you swapped the flywheel. Otherwise I wouldn’t worry about it. Misfire on a bolt on 9th gen would be a very rare event anyways.

ok thanks tbh i was thinking it was something else
