ok i read alot of this on honda-tech (itb setup)
 

i just got my itb's here and i was searching on honda-tech about tuning them. and they were saying that you ca run itb's with a afc hack. some of the guys on there said they've een doing it for a while. and all they do is lean it out and it works fine as long as all the sensors are hookd up right. what u guys think?

Re: ok i read alot of this on honda-tech (itb setup)
 

Sure it will run but I still think it will be a bitch to tune and it probably won't run as good as it should on the AFC. Idealy tuning using Alpha N type maps would be most efficient and probably yeild much better results. Look into running Crome for your setup.

i don't have everything i need to run chrome and i've tried learning how to mess with it and its a bitch lol...i got it running pretty good...just alittle rich at idle and at about 2k rpms...i'm going to get it neptuned in like a week or two

Have j davis tune it hands down

Re: ok i read alot of this on honda-tech (itb setup)
 

that looks hot. But you dont have massive vtak to hear through them :(

Re: ok i read alot of this on honda-tech (itb setup)
 

I think the lynch pin w/ ITB setups, is how well you can adjust the TPS, and how well/stable its mounted.
Ive used CROME w/ itb tools twice. The first time went butter smooth with a very clean driving car.
The 2nd time, the homemade ITB's had some serious TPS issues, and ended up not getting it drivable.

Also, if you wanna go super gangster, run your TPS signal into the ECU's map pin, and just edit the tables accordingly. (you have to use Uber or CROME w/ boost maps due to the voltage range of the TPS)
Josh Ross and I did that once, and it turned out suprisingly well.

Ive also done ITB's with just a MAP sensor on a vacuum log, and the car idled good, and was easy to tune WOT, but anything in between was dicey. The car ran fine, but was very difficult to get a clean fuel map part throttle.

CROME ITB-Tools FTW.

i have the map hooked to the vacuum manifold now...it idles good...just not the best driving and it burns way to much fuel. i don't know how to use crome and dont have everything i need. and i dunno when J. D. can tune it. i know P1 said they could neptune it for 550. but i don't want to do that if j.d. can tune it.

Did you feel that a gold valve cover would make it completly like mine or what? haha

Re: ok i read alot of this on honda-tech (itb setup)
 

i actually just noticed that 2 days ago...i've had the valve cover for a pretty good amount of time now...and just never thought of urs lol...i painted my velocity stacks gold aswell...which that it getting change due to the fact it looks really ghey. and i dunno i just liked the way it looked...plus the valve cover matches the rims.

sweet looking eg dude. I wish my car was that clean looking

edit- actually, if it was, i would have to worry about it getting stolen.

Re: ok i read alot of this on honda-tech (itb setup)
 

well my last one got stolen i guess because i didn't have an alarm on it...but i got one put on this one

Re: ok i read alot of this on honda-tech (itb setup)
 

I tuned an ITB car with Crome and ITB Tools and the car screamed. First car I ever got to take to 10k rpms on the street.

Everything was very butter after getting some TPS issues worked out, very driveable and stock like except for one transient point between the MAP and TPS mapping...very minor but noticable. You have to expect even little quirks with things such as that.

If you are close to Joseph, have him tune it for you...he puts a lot more care and attention if you are nice and bring milk and cookies with you :-*

what do i do with the IACV until i can get it tuned? rght now its not hooked up to the coolant or a vacuum source its just plugged in and hanging

Re: ok i read alot of this on honda-tech (itb setup)
 

man, Chris. Great job on the setup. I didn't actually get to see them in their finished state.

He really spent some time on the tps issue, and it looks like it will be great. Good luck on the tune, turbodeg, and let us know how it turns out! It looks great in the bay!

let em hang...

Re: ok i read alot of this on honda-tech (itb setup)
 

looks good. I know there were many hours put into those itb's. I got to see them before they got shipped out. NIIICE. :y props to you (Chris)
