yeah thats right my car is going back to obd0...i got the most bad *** swap i taking out my b18c1 and replacing it with a d15b2..i know i know i hate to brag about these things but i just can't help it...

anyway how do i convert all the engine wiring back? changing MPFI to DPFI? and all that...someone please help me out cause i have no clue i really hate wiring.

 

help me

 

Damn man talk about a PIA. I would suggest getting a d16z6 intake manifold and just slap it on the b2. Run a Po8 and be done with it. Is this a smog issue? Do you have to run the b2 intake manifold?

Where in nor cal are you? I've got a z6 intake manifold laying around . Email me, noah@norcalcrx.org.

 

is the p08 ecu an obd1 or obd0? problem is, is i'm also selling my p28 ecu and my obd0-obd1 conversion harness thats why i thought i needed to convert everything back i really really really don't want to build another conversion harness...i hated that more than anything i've ever done to my car...such a pain.

 

P08 is the obd1 dx ecu, similar to the pm6, but obd1. So was the harness for a DPFI to OBD1 MPFI or MPFI OBD0 to OBD1? In other words how will your harness be setup when you remove the conversion haress?

 

its MPFI obd1

 

I know that's what it is now, but when you remove the harness what will it be? dpfi or mpfi?

 

oh yeah...**** the extra 2 injectors was built into the harness so it will just be dpfi when i take it out....maybe i might just try to keep my harness or something...if i do keep my harness so its mpfi obd1 then i can just throw on an obd1 intake manifold and use the corresponding ecu....

or how hard is it going to be to rewire for dpfi? i really don't want to spend any money in all of this and i will be losing a little bit of cash if i keep the harness...so if its really not a problem i would rather just convert all to dpfi...

what would be easier?

 

need somemore info

 

Ok man, this is what I would suggest.

-Keep the conversion harness.
-Get a d16z6 or d16y8 intake manifold
-Then get a PO8 or P28 if you decide to do a mini-me.

The easiest way is going to be to use a P08 and a z6 intake manifold. All you will have to do is plug in the ECU, bolt the z6 intake manifold on and plug every thing in. You'll have to use a 92-95 dx or 96+ civic distributor. You will also have to use the 4-wire O2, which you should already have hooked up. You won't have to worry about getting rid of the two extra injector plugs or any thing like that. Plus you'll have a MPFI setup that should run a hell of a lot better than the dpfi setup.

If you decide to do a mini-me, you'll do the same as above, but you'll use a P28 ECU. If you use a z6 head you'll want to use a z6 distributor. If you use a y8 head you can use either a 92-00 dx distributor or a y8 distributor. You should also probably get a cam gear too, but it's not required.

Let me know if you have any more questions, I also have most of the parts you'll need too, z6 intake, injectors, distributor, ect.

 

now thinking about it....i'm going to have complete access to an entire DX engine harness so i might just cut mine off and give it the person receiving my b18c swap so i don't have to help with any wiring pretty much just plug and play for me and them though there will be a lot of sodering. damn

 

Did you solder in the male obd1 plugs or did you make an actual conversion harness? Cutting them sounds like a major pain.

 

i played it safe and made an actual conversion harness that plugs into my obd0 plugs then obd1 plugs on the other side so if i remove it...no problem just my obd0 plugs right there untampered..

 

what obd0 plugs do i need to soder onto my harness, distributor, alternator, 02 sensor? what else

 

What obd1 plugs did you solder on?
