K-Series VTC Tuning Comparison 

self tuned my fg2 thanks to nick. Knowledge from your vids is 10/10

Man this would be awesome if you would do this same results on a stock k24a2 with 50ﾟVTC

This is a topic that a LOT of people claim to understand, and to be nice.... They dont. Looking at your area under the curve (and even up top!) it's like you went from a K20 to a K24 just by getting the VTC dialed lol. I like working from 50, then 40, etc etc then look at both fueling and timing for each VS. The shortcut "edit all tables" method. . Its cool to see how you do it and the clearly superior results.. Nice video!!

Wow!! Nick is spoiling us. Back to back in-depth tuning vids ❤️❤️

This was a huge help for me tuning my 8th gen! Thank you!

Good information. Great to see the overlap differences at certain RPMs.

Im tuning my si right now and this videos a big help

Thank you for the successful simple expression. You reinforced the subject.

Quality content for true tuning enthusiasts. Thanks Nick!

The best vtc explanation video ever! Thanks for the help!

The best vtc video I have ever seen. Thanks Nick!

Thanks Nick 🙏🏻 10/10

Thanks for sharing this info! Enjoying the 8th gen videos 👍👍

Great vid and very descriptive. Not sure why theres not alot of views yet

Great video man!!

Much appreciated nick👌🏾

Knowledge at your expense.... Thank you!!!

Thanks nick

So helpful. Thank you man seriously

Respect nick mad props

Thanks for the insight an tips Nick!

This was awesome!

Another great and informative video thank you! Now I'm interested to know what cam angles you used on my car throughout the rpm range

thank you for making this video

Nice tune, very smooth

Thank you

Jeez man this guy is awesome, I wanna bring my 400km 8th gen to him lol

its realy good video

Love the video and the channel! I was wondering if any power is had if VTC is allowed to run the full 50 degrees? Thank you so much for sharing your tuning knowledge and experience.

A video VTC tuning on boosted applications would be cool. I hear the usuall NA angles dont work as well for turbocharged setups

Very berry nice

👍 nice

Really cool video.Very informative. Thank you for sharing this with us. What are the OE VTC ranges Honda uses for the SI? Do you think they pull back for reliability of engine?

Awesome stuff. Have you done anything similar for K24A JDM with similar mods on stock 25 degree gear?

Awesome video!!! Just seems there is no way to adjust your VTC power correctly without a dyno. I steer tune my car and have to rely on Hondata’s reflash for the VTC angles. Wish I had a dyno.

Nick, would you mind giving some advice on ignition timing and knock limit, for example I notice the K20ITR basemap on hondata K manager runs really aggressive timing under WOT on the high cam, 34 degrees in the midrange. While my car seems happy with this, I wonder if there's any real benefit in running such advanced timing? Would it be significantly different with say 24 degrees from 5000-8000rpm than 34 degrees? I'm assuming this engine (k20A) cannot be knock limited otherwise it would almost certainly be getting knock count with these settings? Interesting also how up top from 7500+ mine only seems to want 28-24 degrees tapering off to 8600rpm, any higher and it will report knock count..... Whereas on the hondata basemap it suggests 32 degrees up top, but my particular car doesn't seem to like this

Great video. 2 things tho. 1. Were all the runs taken on the same tables? Each VTC angle (by 10 or 15 degree increments) has its own ignition and fuel tables, so it may not be a fair comparison if the 40 degree vtc is running advanced tables vs the 10 degree running more retarded tables. 2. Wish you'd've done a 0 degree run. Usually shows better results than the 10 degree across the table

Would tapering further after 20’degrees to 10 degrees help get a little more top end out. It seems when you ran 10 degrees it held the end better just did not have the ramp effect of earlier aggressive vtc angle

What would happen with 0 degrees or no vtc to the power output?

That was super interesting. Excuse my ignorance here but is VTEC an on/off deal or can it be varied?

When you do a run per each cam angle timing and fuel would need to be adjusted as well to get the most potential of each cam angle?

Do you hold ignition timing constant between the VTC angles? I know each angle has a different ignition table. So that would affect power. In order to do A to B vtc wise do you make them all the same?

Is Canada open yet I’m ready to get tuned by nick lol

Are there noticable, in person sound changes between each VCT degree adjustment???

So I'll need a tune after I install this my 1989 CRX K24A2? I have Hondata.

Do you know how ecu controls the different angles with the vtc solenoid does it just use different duty cycles?

Can you take advantage of vtc to help pass pollution test ? In my country they hold rpm beetween 2000 and 3000, if you put 50 degree there would it help for exemple ?

Thanks. But only WOT? How about cruise to mild acceleration?

Hey Nick! Will the 50 degree VTC upgrade be an upgrade compared to performance without type r cams?

Any particular reason why you set vtec that high? From the looks of the graph it wants it lower. I know you know what your doing lol been following you for years I'm just wondering.

Think tuning my 2015 CRV Earth Dreams would be possible? Don't want crazy power, just a little more. Stock is 185 hp, 181 tq. Would be great to see 250.

Very interesting, what cams was used when this test was done?

VTC only affects intake cam ? Or both exhaust and intake

nick where can i book to get my k24 hybrid awd element tuned

Hi do u still tune EFI cars still on hondata? Also is this the k20 or k24 in the 8th gen?

Hello Nick, How does it run in 45 vtc on stock cat?

What can be the best cam angle setup for maximum power in non vtec if we want to keep the vtec engagement at factory setting (5800rpm)?

Hey where in toronto are you located at?

The change from 1:32 to 3:05

can you etune my 9th gen si?

Why is there a dip at 5300?

What does vtc stand for?

Maybe if you point on your graph while you talking people like me that it’s trying to learn understand thanks for your time and effort to teach us but when it comes to teach you need to go more deep into it

Do you e tune ?

What happens when VTC is pinned because of P2V? I have 14.5 compression on k24. 4P deleted VTC with their fixed cam gears when they degreed the engine.
