I have a 93 JDM H22a, 99 Civic EX, I will be running the P28 chipped w/ JDMShit.com's H22a program. How do I run the secondary throttle bodies (butterflies, IABs, whatevr you call them).

P.S. I'm asking this for turbogixxer b/c he does want to look bad.

 

I'm wondering the same thing, so somebody better get in here and explain!!

 

i think fastwannabe has his hooked up so they open at vtec

can you use an rpm activated switch or somthing??

 

whats the drawback from not using them? if any? i have heard you loose low end torque,but in our cases(h22 hatches),it may not be bad.

 

you will lose some low end torque but you will have a slightly better midrange...
Since your ecu will not control the IABs you will need to hook them up to an rpm activate switch or something like that.... I would recommend wiring with your vtec wire so that your butterflies open at the same time as vtec...

 

Does anyone know how to do this? I am switching to a chipped p28 soon, and need to know also.

 

i have mine hooked up to one of the vacuum nipples on the intake manifold..they open when i'm more than halfway on the throttle...

 

Having the IABs not hooked up and not opened will:
hurt your bottom end
make the vtec crossover more of a "hit"
The powerband will be rougher than wit them hooked up correctly


I am talking to expert electian to see if there is a cheap way to make a rpm switch for it

how come its always gotta be hatches? no love for the coupes anywhere....


how bout by vacuum? i think poison has his hooked up by vacuum. though.. he's not running a p28 either... soo.. i dunno... hahah..

oh well.. another bump anyway... lol

EDIT: breakaway just said this... mah bad...

 

like everyone else has said, the p28 won't work. you're almost better off getting a chipped p72 and selling your chipped p28. you'd come out spending less money. the only other option is an rpm activated switch. or if you have an old shift light you could use that.

How is that? explain please

 

Remove the butterfly plate from the IM and run the motor like that. Sure, some low end is sacraficed (you don't really notice much on a 2.2L motor in a light Civic), but throw in some Type S cams and the car will pull hard in VTEC..... basically a poorman's EuroR setup but with more of a bend on the IM of a stock H22 than a EuroR IM.

as a p28 doesn't have controls for secondaries where a p72(gsr) does. you can wire the system so that the secondaries open at the same time as vtec which would be better than nothing. going that route you'd probably want to do some fuel tuning of some sort, or chip it.....

this is what i was talking about i wanna try this sooo bad,but boost is calling

sorry, love the coupes too!

 

i may have find a cheaper way (than the window switch) to wire the IABs up
Now just have to find the parts

 

It's a good thing you live 15 minutes from me.

 

I also hooked mine up through vacuum. Take the line off the top and hook it up to the intake manifold. drive it, and if you dont like it then worry about spending money on another solution

If you check out Hondata's website there is thread there thats say the P28 can run the IAB's. It's says that the ECU has the controls on it but just needs to be set up.

By the way here is the threadhttp://www.hondata.com/forum/v...=iabs

 

how good is the jdm **** program has anyone ever used it

Yeap, thats how mine is chipped. My secondaries engage the same time as vtec all controlled by my ecu. Im running a program called chrome though, not hondata.

 

there will be a plug on the IAB's one black one pink
wire black to 12v power source such as one the yel/blk wires from one of the injectors it doesnt matter which one then you can wire the pink one to the vtec wire off the vtec solenoid or tap into A4

this makes IAb's engage with vtec

i removed mine though...i didnt notice a ddddddddaaammmnnnn difference i have a p28 custom maps and the 2.3L loves the IAB's removed

Wow you obviously have no clue what you are talking about. THe P28 does have provisions to control the IAB. As a alterniative (for the guy wondering how he can activate his IAB's) -- MSD makes a RPM activated switch that is cheap and will do what you need very nicely.

Maybe you should take that out of your sig since you ARE spreading misinformation

 

I think i'm going to wire them into the VTEC wire. I'll try that and see if it really has any difference.

After I get my new ecu, i'm going on the dyno to do a quick test and hopefully i'll be able to see a difference.

 

Update:

I yanked the pink IAB wire out of the A17 jumper and just spliced it into the VTEC wire (I believe it is A4) worked beautifully and now they open with VTEC.

EDIT: This is OBDI by the way.
