From what I read I should go with the p12 with my f22a1, and also with the h23 I'm manifold swap, which is in my near future plans, just wanna make sure before I go get the p12 and find out its not right, also which manifold to go with I read the a6 with the h23 is a better set up, is there a difference between the f22a1 and f22a6 manilfold?
-
Yeah, there is a difference.
The f22a6 has butterfly valves inside, which are controlled by the ECU. The P12 wont control these.
The a1 doesn't have the butterflies. -
the pt6 is what i have heard to run with the H23 IM upgrade.there is a sweet DIY on the H23 IM and it has some useful info on the topic you seek .
A man that keeps looking back can't see whats in front of him.Comment

See this is why I'm getting confused cause the above information I listed was things I read on here but this is why I wanted to clarify it, so basically a6 manifold pt6 ecu h23 plenum and throttle body? And the p12 would be a waist of money?Comment

page 2 and 3 they talk about the ECU for the IM swap .

this is what I gathered from reading that use the pt6 ecu with the h23 manny the a1 and a6 runners will bolt up, now I read somewhere else the guy suggested the a6 cause of the length on the forum the guy said the h23 cause its tubualr? Now ? About the butterflies and black box if I use the a6 will I need the black box and are the butterflies are in the plenum correct...sorry lack of sleep and being at work got my brain workin to hard hahaComment

This is the only thing I see about a black box. I'm very interested in this as well, but it's more of a future plans interest than a will do soon interest. I'm not too sure if I'm even on the right target here. LOLOriginally posted by cokinut View PostComment

Wooord haha ya its probably gonna be a little while for me too plus I still gotta figure this shit out...if you find out anything else you should let me knowComment

Only ? About that reply is when he's talking bout the manifold he's refering to the the actual manifold right or the plenum?Comment
-
I'm guessing black box is a reference to the vacuum distributor which has vacuum lines going to the plenum. when he says manifold, he could mean manifold, however i'm assuming he means plenum since a lot of times people group the manifold and plenum together when they say intake manifold.Comment
-
That's what I was thinking, as far as the black box goes though I know its under the manifold "iab intake. Air. Bypass. So ya guessing your right, so its not absolutely need and can be bypassed but better off with it..someday soon ima try my setup like I listed above from what I read it should workComment

In this thread it says to use the a6 ecu and black box,Comment

Found this too thought it might be useful
I know you guys have not posted on here in awhile but here this info for anyone else who might need it too. The IAB's are vacuum operated, and yes they are electronically operated by the IAB black box that is bolted under the intake manifold. If you want to use the PT6 ECU that came originally from the F22A6 on your LX you would need to wire the IAB black box to pin A17 on your ECU, the PT6 will also give you better HP because it has stronger fuel maps and ignition timing. But you could also use your F22A1 ECU which is a PT3 and just not wire the IAB black box at all. All you would need to do is take the vacuum line from the IAB diaphram and run in directly to the intake manifold (instead of going to the IAB black box first). The problem with this is that the IAB's will open sooner than if you have the IAB black box connected, with the IAB's hooked up straight to the intake manifold they will open anywhere from 2300 rpm to 3000 rpm which can hurt your low end torque a little bit, but with the IAB's hooked to the black box they open at 4900 rpm via the ECU.
Now I don't know exactly what the OP is lookin for, is it HP and TQ or is it fuel economy. In my honest opinion, I think you should grab the PT6 at least so that way you have the ECU that was meant for the motor because the A6 has the more aggressive cam than the A1 and etc. And as for the IAB's try it with and then without and see which way you like it better:thmsup:.
I have a '91 LX and I did a H23 intake manifold (also has IAB's) swap on my A1 with the A6 cam, PT6 ECU and as for right now I haven't been able to find the IAB black box around the junkyards here yet but I still have fun in my CB7 grocery getter
, and also have a budget built plenum spacer. It all depends what your looking for, if there is anyone who wants to add or correct anything be my guest.
P.S almost forgot to say that the F22A6 and the F22A1 have the same block, the only things that are different on the motors are the heads. Hope this helpsComment

Ecu / Iab
First of all, In my oppenion if you are running butterflies it is not worth hooking them up to straight vacuum. Doing this will have them open when you are past about 50% throttle, regardless of what rpm you are at. this means that if you floor it at idle your butterflies will be open an entire 3000 rpm earlier than you wanted.
My suggestion would be to hook them up correctly, or not run them at all.
As for the ecu, depending on how much money you are looking at for getting one, I would price out the cost of a chipped p28. Especially if you are planning on doing any additional modifications later.
I am certain that someone here has a bin file you could get and run, or find a tuner in your area.
If that seems a bit extreme then I would put the p12 as the best option, then the pt6 as the second best.Comment

ima blow my head off haha now your saying the p12 when above dude said that wouldn't operate the butterflies, and I planned on hooking the black box up as long as I can find oneComment
