  1. Faint clunk noise when turning full lock on first startup

    You’ll need to have the car on a lift or ramp so the suspension is loaded with the full weight of the car. Have someone turn the wheel while another is underneath inspecting the bearing assembly and spring position. Disclaimer: be absolutely sure the vehicle won’t shift position on the ramps. 😉
  2. Faint clunk noise when turning full lock on first startup

    Check the bearing assembly below your top hats. They can wear down prematurely and exhibit the symptoms you’re describing - especially on track setups with aggressive front negative camber. I typically inspect on an alignment rack but Jack ramps should also work. Just make sure the suspension...
  3. Public Service Announcement: Si Fuel Injectors

    The dealer hooks up the car to their proprietary scan tool, IIRC, and runs a real-time diagnosis on the injector performance.
  4. Design's Long Term Ownership Thread - 2017 Si

    Update at 112K. A little late to post, but after nearly a 12 week downtime the new injectors finally arrived from the dealer. Car now runs great with the new injectors in. Honda’s inventory backlog has been disappointing, to say the least. And I’m hoping this is the last time I will have to...

    It does. Just be sure to enter your VIN with the order to ensure you get the right part. 👍
  6. Rear Suspension Clunking

    Swap the shocks (not struts) and mounts. Then swap back the mounts/bushings if the noise follows to the other side. Only other thing that comes to mind is the LCA or trailing arm bushing.
  7. Why Si vs Type R? Cause MPG lol

    This is my typical mileage… this one after a 500 mile full road trip through back roads, side streets, and some scattered traffic. Pretty much normal/spirited driving the entire way. 115K on the odometer on KTuner Map 2. 😎
  8. Public Service Announcement: Si Fuel Injectors

    MSRP is $601. Anything above is an overcharge from the dealer. Injectors are still on backer online but can be requested via CBO through any Dealer. EDIT: Getting word that online dealers will soon be stocking the injectors. You can try Jim White Honda or Honda Parts Guys to see if they’re...
  9. Public Service Announcement: Si Fuel Injectors

    The most reliable source is a prepaid critical backorder through the dealer.
  10. Public Service Announcement: Si Fuel Injectors

    Here are a couple photos. The kit includes the fuel joint (not fuel pipe) which is strongly recommended to be replaced due to the crush assembly. The part ID for the injectors is similar but includes an extra 0. To my knowledge, these can no longer be purchased independent of the fuel joint...
  11. Difference between 2020 Si suspension and HFP?

    After riding on the HFP system, I will say it is arguably the best spring/damper combo you can get under $2K. IMHO, there's no other setup that offers the range of flexibility that HFP does. I was very skeptical of what was being described as "softer" spring rates. But I actually think they are...

    Yes, they come packaged with the fuel joint.
  13. Public Service Announcement: Si Fuel Injectors

    And to clarify, "first come first served" simply means waiting in line after placing a CBO through the dealer.
  14. Public Service Announcement: Si Fuel Injectors

    I was quite surprised myself. After doing a bit of digging, and as mentioned earlier in this thread, this appears to be their third mass injector failure in under 5 years. Why they didn't rotate in another supplier like Denso is beyond me. I've heard there are still over 2K prepaid orders in queue.
  15. Public Service Announcement: Si Fuel Injectors

    It took nearly 12 weeks but I received mine. They are still on backorder and subject to first come, first served.
  16. K.con question

    If it were me, I'd take to the dealer to have hooked up to the HDS (or have your mechanic do if he has one). https://www.civicx.com/forum/threads/misfire-cylinder-1.76356/#post-1153508
  17. What to track on Ktuner V2

    There are plenty of varying opinions on the topic. What you display often depends on what you want to monitor in real-time. Here's what I track: AFR STFT LTFT K Control K Count (or DIFP) ECT MAP/Boost IAT 1 IAT 2 When my injector began leaking, my AFR immediately went rich at idle, my K Con...

  19. K.con question

    Yeah they’re on nationwide backorder. I heard their supplier released a few recently. But there are reportedly over 2K+ orders in queue. And some have orders still pending from May. MSRP should be around $600 for the injector/pipe assembly, plus another $200 for the fuel joint pipe. Used is...
  20. K.con question

    Sounds like injector 1 “might” be leaking. How’s your STFT at idle?
