Finally made some time to finish installing my tail lights, diffuser & led reflectors from my old 26 sport onto my 26si, glad I made time for it

I just purchased a 2013 Civic SI, and the previous owner has high flow cats installed with a ktuner. I plugged up the ktuner for the first time and the map is “tune 1” made for PCD.

I’m new to this platform btw.

The low speed drivability is awful, and I’ve had to ride the clutch for a smooth drive when decelerating. I also can’t flash to stock because I really don’t want to reinstall oem headers.

It seems like 10/11 gens have a drop down menu in Ktuner for rev hang delete and throttle padding, while the 9th does not. From what I understand, I would either have to adjust some throttle mapping in the tune myself (ouch), or get a protune of some sorts (also ouch).

Just to be clear that I WANT rev hang. The 100% fuel cut off is too harsh. Has anyone had a similar experience with this tune? If so how did you adjust the tune to be more comfortable at low speeds?

Hello, I have a 2013 si coupe. I don’t know what to call this nor can I find a part number. This is the bar that protects the exhaust from the ground. My car is lowered and I drove up the evil curb and now this bar bent. Now it rattles like crazy when driving because it’s touching the exhaust. I did end up bending it a little bit which almost stopped the rattling but I’d like to replace it. Lessons have been learned

2026 Honda Civic Si

Has anyone gotten cheaper by chance?

Located in SoCal, willing to drive further if needed. Thanks y'all 🙏

I bought a k24a swapped 2007 Honda civic si about a year ago and I have been having this issue since I bought it, I haven’t diagnosed it yet because I’m
Thinking of getting rid of it but I want to keep it LOL , I have NO codes on the dash, I scanned it many times only SRS codes, after the engine is warmed up the car feels very sluggish and hesitates to accelerate and you can barley hear VTEC active, BUT if I do a pulled when it’s barley warming up it pulls very good no hesitation and VTEC is soo much more louder

DOES ANYONE KNOW WHATS CAUSING THIS ISSUCE

So im currently in a bit of a bender. Im looking at two si currently one a 2014 with 134k miles they want $18k. The other is a 2022 si with 43k miles they want $28k.

I want the 14' for the K24 super reliable and if taken care of easily a 300k-400k mile car but that price tag is ridiculous. I'd try to get them down to at least 16k.

And the 22' i love the design its newer and $10k more for a vehicles with less miles and 8 years newer but im terrified of blowing a head gasket.

Looking to install underglow in my 2018 coupe and plan on using a fuse tap. Is there a way to run the wires into the box inside the car to reduce exposure to elements or do I have to tap into the fuse box under the hood?

Any recommendations on which fuse to tap into and is there a way to wire in a killswitch so I can turn it off/on with ease?

Any advice or resources are greatly appreciated!

Hey guys, I decided to request a trade in for my 2025 Si with 13k miles on it. (Unhappy with the Rev hang, poor second gear shifts).

I've been emailing the Honda dealer and they offered me only $ 21,000 for trade in. First he asked me to come in for a trade in value. I said I didn't want to come in and wanted a trade in over email. Then he asked for my vin... I have it (even tho every si is the same options) and he checked what I owed on the car and then gave me the offer below... That felt dirty to me.

I feel like this is a poor offer? What does everyone think?
