Itb's

[beeza]

Can I simply install a set of itb's on my automatic d16y4 without tuning?

Just reset the ECU and go?

[FLICK]

no. lol

[beeza]

Damn.They def. need tuning aye.

[hisoka]

yeah definately tuneage.

[beeza]

Thanks Hisoka.

[FLICK]

plus you really need to find someone who really knows what there doing with itbs. heaps of tweaking involved to get these itbs to run properly. not any joe blow can get these to work well. So find someone with a good reputation. Toda is going up to qld so it would be a good idea to talk to him as he is pretty switched on when it comes to tunes

[beeza]

Yeah,I won't be doing it...it was only if tuning wasn't required.I would buy,bolt on,play and if no like,sell,if like then keep,but with tuning,nah.Getting too expensive,cause I would need greddy or the likes.

[beeza]

What would happen if U did just put it in and reset the ECU,would it just not idle and run sh!t?

[xntrik]

why do you want to run it so badly on a stock engine.
as far as i know it runs worst than standard manifold, if untuned.

[AXS]

might want to do a little head work and a full aftermarket ecu to tune, then ul feel the real power in the ITB's

[EKhatchguy]

You would probably blow your motor. The ITB's allow for more air to rush in at once. With stock fuel maps/ignition timing, you'll run extremely lean and bye-bye motor.

I don't.It was more a thing of 'can I do this on the cheap'? Just something to have some fun with.

But the answer is no,so I'll let it go :thumbsup:

Gotcha!

I see,ah ha.Thanks mate.

[dongsoo]

if u add ITBs onto a stock engine. how do u expect it to run at all ? (map/afm will not work)

[vinnY]

vacuum box

it'll probably run, just barely and probably terribly too

[beeza]

Like DYNALL'S? (http://www.ozhonda.com/forum/showthread.php?t=78676&page=5),then it will run?

Word!

[vinnY]

no he's just got an airbox.. vacuum box is just something to run all your vac lines to
i.e. 1 from each tb, to brake booster, map sensor, iac, etc

[riruiz_88]

what if you only work the head, and leave the bottom end standard? would that yeild a good power increase?

[vinnY]

the way i see it, itb's aren't about making power
they're about response and shifting the power band to however you like it
mid range ftw

It will run on the stock ECU, but its best to get it tune

[xntrik]

I forgot to mention when it gets tuned, I've been told that you have to go to a tuner that knows ITB's apparently if you dont tune it properly, the butterflies of each body doesnt open properly.

:x thats as far as I know. Can anyone confirm this?

[geeang]

All depends on the engine setup, ITB setup, etc.

My JDM B18C with A-sport ITB's ran fine, and idled perfectly on a stock DC2VTIR ECU. You could feel power loss higher up on the stock ECU though.

Tuning was fiddly, took about 5-6 hours but the end result was fantastic.
Actually idled better on the stock ECU than the tuned Hondata :D

[xntrik]

Wow really better on stock ECU than the Hondata? D:

Just the idling was better, the rest the tune overwhelms.

Idle on stock ecu ~800-900rpm
Idle tuned cold ~200-300rpm
warm~400-500rpm

:D

[xntrik]

Wow what a low idle!
Good stuff man,
But I highly doubt you wanna leave ITB's untuned for long ay,
otherwise its just for show.

[beeza]

Thanks guys for the input.
