Need some opinions on 03 civic si mods
Alright, someone told me i should get the hondata for my car. I didnt really know what it was so i was like...aaaaahhhh, maybe....whatever. Well i get home and start lookin up **** about it and go to hondata.com and holy ****. I'm really likin what im readin about it and what other people have told me about it. So i was thinkin what would it be like if i got the new hondata....i've already got a V-AFC II, and im planing on getting new camshafts and all that good stuff and building my engine. I just need some opinions from guys that know more of what their doing and how realistic of a gain i would get from this. Thanks
Hondata is the ****. It changes the whole personality of your car. I dont think you really need the vafc anymore, unless you want to keep it for the bling factor. You dont get any gains on the dyno, but the power is distributed more effecently through all the gears. I know that not adding hp on the dyno sounds like ****, but trust me, your car will feel much more powerful when your shifting at 7800 rpm
hondata works great on all motor or turbo. ask for Doug he tunes his **** rite..

It depends on what you are looking for on a dyno. If you think the highest peak on a dyno represents whay you're going to notice the most, guess again... that's just a tiny point among thousands of tiny moments.
Now imagine if you took two dynos and flipped them upside down. Now imagine the dynos are bowls of water. Regarless of how deep the deepest point is, if one has more volume it will hold more water than the other.
THAT is the factor you'll notice more than a peak on a dyno chart... the overall area of power... and while Hondata doesn't add a huge spike anywhere to the dyno chart, it DOES add a great deal of area.
If you are considering it, look on ephatch and k-series, and here for someone in your area that has it already so you can experience it firsthand before buying. That's what sold me on Hondata, and what they say is true... the EP3 becomes a whole new car... I'm very happy with it.
The VAFC is not much use for a NA EP engine... Hondata does the optimal fuel/timing tuning already, the VAFC will be in the way... and dont mess with the A3 vtec engagement point, it can only do harm to your mpg with no gains.
If there ever are some good cams for the EP3, the VAFC and some Dyno Time could prove useful.

yes but correct me if im wrong but you would still notice the overall powerband difference on a dyno

Yes, its a matter of looking past the peak point and noticing that there is an overall gain, and with hondata, there is an obvious overall gain.
Lots of people get too wrapped up in the Peak HP number.

True, there is a difference between peak HP and usable HP. No one wants to be at 6000rpm on surface streets to get into the power band

I don't have a Hondata on my EP (yet?) but I have one on my ITR. A tuner can definitely add a lot of useable power w/a Hondata. My ITR's a joy on street or track, with a seamless activation of VTEC that's a big part of the overal feel of it.

I wouldn't hesitate to recommend a Hondata.
