  1. The Tuned CivicX Experience & Reliability Thread (for all models)

    I am testing a 2015 1.8L engine in a RV6A kitplane. A lot of people who do not fly will find this really weird, but it is quite common now days with people who build and fly kitplanes. Vehicle: 2015 1.8L Total tuned time: About a year Total tuned mileage: About 40 hours. Tuning device(s)...
  2. Anyone graphed the cam degree changes on a hard pull

    Has anyone graphed the cam degree changes (IN or EX) on a hard pull? I am not sure if it is even possible, but if so I sure would really like to see a screen shot or two. Ideally with the RPM and Boost. Thanks! Charlie
  3. Power Per Liter Hondata Flashpro Basemap for Si-

    D-Rob, Thank you. Hate to be a bother but can you confirm that either Hondata or KTuner allows you to graph the CAM and EXCam on the K20C4 so you can see what the ECU is doing with the VTC on a hard pull? Charlie
  4. 2.0L Help understanding VTC variability of phasing

    I suspected that is the case, as I mentioned in my first post. I just hesitated on this because normally a pulse width duty cycle is just perceived as a reduction in voltage and usually comes from a logic level at 5v. But nonetheless, I agree with your comment - even given the spool valve...
  5. Power Per Liter Hondata Flashpro Basemap for Si-

    Thank you. Do you know if the cam angle tables adjustable for other engines like the K20C1 or K20C4? If this is too far OT I apologize and will create another thread. Thanks
  6. Power Per Liter Hondata Flashpro Basemap for Si-

    Poor choice of words on my part, sorry,. I was thinking, and may be I am wrong, that based on your conditions that there would be more advance on the intake. I see it at zero. But may be zero is perfect. I was also interested to know if it was possible to show a graph of the intake and...
  7. 2.0L Help understanding VTC variability of phasing

    That makes sense to me too, but with the system, partial movement of the spool valve is not possible. The only way that would be possible if the spool valve could be controlled to move partially from the resting position where spring pressure holds it in place which opens the path to retard...
  8. Anyone boosted a K20C2?

    Tell us more. How much boost? Boost control?
  9. Power Per Liter Hondata Flashpro Basemap for Si-

    I am interested in the Cam and CamEX advance. I see it shows zero degrees for the cam, which does not see right to me if you were in 3rd at 68MPH at 23" MAP. What am I missing? Is it possible to show a graph of the CAM and CamEX degrees advance on this run? Thanks! Charlie
  10. 2.0L Help understanding VTC variability of phasing

    I understand that VTC varies cam degrees (phasing) by way of varying the oil pressure that goes to the cam gear by movement of the spool valve. In other words, I understand that when the VTC spool valve is energized it moves so the oil is routed to the oil passage that puts pressure on the cam...
  11. Anyone boosted a K20C2?

    I would sure like to hear from anyone who has boosted a NA late model (DI) Civic like the K20C2. Especially if you used Ktuner or Flashpro. I would be real curious if the project required swaping ECU with something like a K20C1 or K20C4 or just add a Bar 2 or 3 MAP sensor. Thanks. Charlie
  12. 27Won Full Turbo Back + Review and Sound Clips

    Excellent work. Thanks for posting the pics, that really helps. Any chance you will have some dyno charts to compare? Do you use Flashpro? and if so any changes? Charlie
  13. Best Place to get Service Manual for wiring (not Owner manuals)

    I see lots of places to get owner manuals but no luck so far getting a hold of a service manual with wiring schematics for a 2018 K20C1 Fx8.
