9TH GEN CIVIC SI TUNE

[CalibratEd]

I made some fuel adjustments to dial in the MAF. Load the file and create another log.

Again, sorry for the delay, some life events happened. I downloaded that maf rev tune you sent and did a datalog on that. after 4 min my car did the same thing, when i press on the gas it's like it's not going through, and the engine will try to go but my exhaust kind of just stops idk. lmk your thoughts and hopefully this datalog is enough because I cannot get anymore without my check engine light going on and doing that thing. Thank you

The new intake is another variable to add into the mixture. The calibration will need to be adjusted. Reviewing the the log the MAF table does not look very off and the AFR dont look bad either. The car is throwing misfire codes. I don't see any WOT pulls in the log so i assume you logged the car after driving it hard. I do not recommend driving the car hard until you have the calibration dialed in.

Also, I suggest you run the speed density calibration file i provided. These cars run better in speed density once modified. You said it threw check engine lights initially. I added more fuel just in case.

Yes I have a skunk2 cold air intake. I also don't remember if I mentioned about my stage 3 clutch, it has a lightweight flywheel, wasn't sure if that is something to include in the calibration or not. I also want to mention when I am shifting it feels very bad. Sometimes I have to stomp on the clutch and sometimes I have to force the shifter into the gear. It sounds bad when I do it but I kinda have to in order to keep driving. I have attached the datalog I just did for the calibration you sent last. After 7 min it did that thing again where I couldnt gas it. Let me know, thank you

I cleaned up the fuel. Load the new file and datalog the car.

Regarding shifting the car, that is not tune related. I would double check if anything went wrong during the clutch install.

Car is behaving pretty good now, it was just tranny fluid ig. Was finally able to get a good datalog in, about 13 min, mostly city driving so no high speeds really probably the fastest was a little over 50 idk. I attached the datalog as well as the calibration I used. Let me know and thanks in advance.

Double check you uploaded the correct log. The log posted is only 3 minutes. The 13 minute log would be better as its more data for me to work with.

Don't know what happened to the log, kinda pissed lol. I was able to get one for 8 min before my car turned off. Also, some lights came on while driving (Power steering, VSA, Hillstart assistance, check engine(emission)) Hope this is good for now, thanks again.

I’ll take a look at it when I can. The lights turning on sounds a bit odd.

Ok I cleaned out my fuel injectors and car didnt throw any codes while I was datalogging. I got 19 min of driving in hope this is good. Transmission made some sounds and car was shaky when I press the gas. Let me know, thanks!

[CalibratEd]

I adjusted the fuel. Load the new file and create a normal drive log. Part throttle fuel should only need one more revision.

Apologies for the hiatus. I just got a new act stage 2 clutch installed and fixed an exhaust leak so she's running solid now. I am running a skunk2 cai, skunk2 exhaust, and skunk2 dp. I got a datalog in right away for about 15 min. I attached it below along with the calibration. Let me know if there is anything else you need. Thank you.

The car was running a bit lean. I adjusted the fuel. There was also a few counts of knock so i reduced timing in those areas. You should be good to normal drive (No WOT) the car until you get it properly tuned. Reach out when you're ready for a full Etune if you don't already have a tuner. My contact info should be in the tune.
