i want to use a P28 ecu with a hondata set-up to run my boosted h22, but i heard from a little bird that the p28 cannot run my secondary intake rudder, is this true? and then i heard that by using the p72 it could control it? would using the p28 hurt my engine? do i really need the secondary intake rudder? please help

 

yes, this is true, it will not control your secondaries and you'll lose some low end. you can run an aftermarket rpm switch and rig it up to the secondaries so that they turn on at the right rpm.

i, personally would make sure you have secondary control if it's your daily driver. our hondas already don't have low end torque and I wouldn't want to take even more of that away.

 

Or get a skunk2 im or euro r and you want have the secondaries anyway. Thats what I'm going to do. Run the Sk2 with type S pistons and crower stage 2 cams. I don't have to run the egr either,...there is no place for it anyway. my 2 cents

 

True that your secondaries will not work with the p28 but you can allways remove them. I dont think the are really that important considering that the skunk and Euro R manifold do not even use them so why would it hurt to take them out.

 

Secondaries are on your intake manifold. When they are closed it allows your car to make more bottom end torque. Then right before vtec they open this allows for more air flow for vtec. So the purpose is to make it good for lowend driving around town then when you get on it they open for max air flow.If they are just staying closed and never opening you will loose alot of topend power. So fafsa if i were you i would open your hood and take off that vacum hose on the diaphram thing to the right of the intake manifold. Just make sure you dont mix up the diaphram with your fpr.This will make sure your secondaries are staying open scince the p28 will not open them.

 

yes your secondaries or butterfly valves are located in the 3rd and 4th stages of the intake manifold and the iab valve controls these secondaries and the p28 does not control the iab valve since there is none.

thanks man. i just took a pic of my IM can you show me which one it is exactly? i dont want to get it mixed up. thanks everyone for helping out a noob

 

If you're gonna get a hondata installed then that program can also be used to controll your butterflies even with a p28

 

like the guy above said, you can use an rpm output from the hondata to run your IABs. No reason to have a P72, plus a P72 will open secondaries at 5800...which is junk. You want it at 4900 (h22a4) or custom whatever works best.

To be honest with a turbo setup why would you care...leave them open always....if you hitting boost anytime before the secondaries open you will be seriously restricting flow with them closed.

 

thankx guys ... so i should just get the p28 and leave them open all the time by removing the vaccum hose on the right... in the front of the manifold right?

what about a p13, the guy i am getting it from said he can program the p13 to iab and the egr to open and close when i want them to..... what should that be? anyone know the stock settings for this or where i can find them?

wait..i thought you're running boost and hondata? so why are you even thinking about the p13? you know that you can't use hondata on a p13 right?

 

this is fafsa's freind

can anyone circle which part we need to pull out so the secondaires will stay on all the time? he plans on using uberdata so the option with keeping it open with hondata is out of the questions

just go with a p28 and call it a day.

you see on the right front corner of the plenum....that big circle with a vacuum line going in....thats the one....take that off and they will always be open....

i wish someone had told me that you could have hondata control the iab's instead of buying a p72.....damn

 

They are electronicly opened by the ecu. You have to remove the ENTIRE butterflie plate in order for it to be open all the time.

any truth behind this?


and mgags7 sry but i just want to be 100% sure is this it? and do i just pull it off and zip tie the line down or what else do i do?.... everyone's gotta start somewhere, again we appreiate all the help

instead of getting rid of the vacum hose i am just going to get a uberdata p13 programed to open the secondaries at 4900. sound good? any thoughts, i am aware that the s200 system wont work on the p13

You dont have to remove the plate when you hit 4900 it cuts the vacuum and opens the secondaries.So by removing the vacuum it just stays open before the actuall set point.If you just wanna get rid of the whole system you can remove the intake manifold and the iab plate comes right off.Just remove the vacuum and call it a day.

actually all u do is pull the vac line off, they are open in its neutral position, so if you pull off the vac, they stay open

Nuff said

That's why I'll be running the p28 in the near future

do i just leave it tied down somewhere in the engine bay?

 

OMG man. Do you see the fact that your breather is left open ? Notice the oil and **** all over the place? lol might want to loop that to the intake or just stick a little K&N filter on the end of it. Also, the VAC line you all told him to cap, looks the the line the controls the EGR to me. If there was the black plastic clip that holds the injector harness in place it would be sitting right ontop of it.

The secondary vac line is the back of the manifold. Very upper right hand corner. Very small vac line. On the manifold you can see the actual spring/mechanism that opens/closes the secondaries. lol you people are nuts.

And to CBR-7 you do not need to remove the entire plate for them to be open. Pull the damn vac line off the back and watch them stay open forever. With the diaphragm disabled it will stay open.

EDIT: just noticed, you dont even have an intake, you stuck the filter directly on the throttle body.
