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)...
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
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?

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...
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
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...
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...
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
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...
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
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?
