Re: (Built B16A)
I'm not much of a guru of the Z1, VTEC-E, or turbo setups, but from the sound of it, it DOES sound like your injectors need to be changed since you're using a P28 ecu. As you say, the Z1 has 180-190cc injectors. Try using a set of 92-95 DX, Si/EX or B-series injectors to possibly satisfy the P28, but put your wiring back to how it was BEFORE you got the solid check engine light.
Altho, the Z1 engine isn't really a good engine to add performance enhancements to begin with. Especially that horrid VX gearing...bleeeaaah!!!!

hahha.. word to your mother, but i wanted to be one of the very few to take the Z1 block and turbo it.. hahaha, don't ask why.. after i get it running, i'll prolly go over to the JDM D15B.. but i wanna make numbers on this 1st.. its just fun..
and BTW.. im rocking a EK EX tranny (steel shift forks)... and i know.. hahah, the VX gearing is at the bottom of the list..

Re: (K@man)
hey katman.. just a wild idea.. i have DSM 450's on the way.. you think i should do as i did before, run the P28 with the 4 wire o2.. disabled knock, and run a basemap with the 450's?
atleast the basemap is created on 450's, insteading of trying to get the P28 to run on my 180 CC's.

w3rd.
For the VX P07 comparison to the EX/Si P28 wiring differences, it is true that you only change one wire. The rest run to the necessary pinouts.
As for D3, P28 D3 pinout doesn't look for anything.
On the EGR subject, the wiring doesn't matter because the P28 doesn't look nor have EGR function on it -- so it's a dead sensor.
The only thing and key to make it run "right" is to make the ECU happy. Give the sensors and everything else it's looking for. Once that is acheived, then tune the ****.
If you wired the 4 wire O2 sensor properly to the pinouts, then the P28 shoul see the 4 wire O2 sensor and should function, unless of course it's a problem with the hardware, or ECU itself (seen it many times). If you're not throwing a code, or any codes for that matter on the P28, then it's neither the ECU or the wiring involved, but could be the hardware, or mappings you're running on the ECU.
To me, it indeed sounds like the injectors. For all the P28 knows, it's sending the correct signal to the injectors, but the injectors are just too weaksauce.
And bleh on the VX motor too, boost the **** out of it then go for a D15B

werd to your mother.. ive been looking desperatly to pin a acutall CC number on the VX injectors, but ive come to no sucsess... but im desperatly hopeing that once i get Si injectors in it.. the P28 will run normal. after that, go DSM 450's.. uberdata and visit the dyno..
and yes, i want to place VX boost numbers, and after that, the D15B goes in. i already have one on order for $250.. shhwweeet deal!

Re: (Built B16A)
Is there any way you would have access to a diagnostics scanning tool? If you could look at the fuel trim the ECU is at, this would definately rule out the injectors as the culprit...although the more I think about it the more I am convinced that the small injectors are your problem.
The P28 ECU sends a signal to the injectors to open them for a specific amount of time. The P28 also thinks it's dealing with 240cc/min injectors. The smaller VX injectors put out less fuel than the 240's for the same amount of time the pintle is open. This causes a leaner than ideal condition, and the o2 takes note of it, widening the pulse width.
Get some 240's in there and let us know how it rolls.
I'll get my pictures of my resistor box install back up and link them in my writeup on the H-T Knowledge base for you.

Re: (K@man)
is your VX obd1 or obd2? if its obd2 their may be some differance in the obd2 injectors aswell. not are they to small, but their could be a differance in obd settings.
i would change the stock injectors out for some stock p28s like everyone else said.
disable the knock sensor.
also if your hooking up your wideband disable the o2 heater, and unhook the sensor. this way the only signal going to the ECU is from the wideband.

Re: (Snail Tuning)
its a OBD1 92 to be exact.
and thanks for the help guys.. im going on vacation tomorrow.. aaahh.. mexico for a week.. so when i get back, this will be one of the 1st things i'll be tackeling! i WILL keep you guys posted.

Re: (Built B16A)
After re-reading your first post and finally going over VX wiring on my own this morning (for the first time ever). Here's some info I found out which is a sort of recap....(some of this may be redundant)
P07/VX vs. P28/EX-Si ecu pinouts are similar, but the P07 uses extra pinouts the P28 doesn't use, and these pinouts are:
A11 = EGR valve control
(empty pinout on a EX/Si ecu plug)
D12 = EGR lift sensor input
(empty pinout on EX/Si ecu plug)
D3 = VX H02S heater control
(empty pinout on EX/Si ecu plug, but used for knock sensor pinout when going B-series and using a full stock DOHC VTEC ecu)
D8 = VX H02S input
(empty pinout on EX/Si ecu plug)
D16 = VX H02S ground
(empty pinout on EX/Si ecu plug)
Both P07 & P28 needs and uses the A6 & D14 02 pinout locations.
You said you cut those 2 pinouts in your original post. You shouldn't have done this to begin with. Put A6 & D14 back to how they originally were to please the P28. It's ok to leave the extra VX 5-wire 02 wiring intact (as listed above), they will just become dormant/unused once you perform the single wire fix that Poison and some others have mentioned.
And speaking of this VX single wire fix for 4-wire 02 use, DWNTHEHATCH has a VX wiring tech page here:
http://www.geocities.com/dwnthehatch/vxwiring.html
....I'm not fully sure here, but is DWNTHEHATCH's info the correct single wire fix we're all talking about? if so cool, now I know. The only thing I'm not sure of in his article is if he's using a VX engine harness, but I guess were suppose to assume he is.
And as already mentioned, you should try non-VX injectors. I have a set of a GSR injectors if you'd like to try em out Built. Lemme know when you get back from meh-hee-ko.
PS: I'm amped to make my own VX wiring article now

Yes, dwnthehatch's little article is correct. I know that cuz he hit me up a long *** time ago on that about help for wiring on his B18 into his VX.
I'll explain a little later, gotta go to work. argh.

B18C into his VX chassis using the USDM B18C1 harness! not the Z1 like myself.
the thing is keeping mine. even though the EGR would be something "extra" the O2 would need to be satified...
so does my VX even have a knock sensor..? (too lazy to crawl underneath)

i totally kicked the 5 wire O2 plug to the side, and ran my own harness for my bosch O2.
i cut both A6 and D14 and ran my own wires to the ECU pinout. and then i taped into D22 for ground, and also tapped into A25 for the power.
the way that O2 is wired, should be ok..
it started and gave me no check engine lights, but ran like ***.. now the more and more i think about it.. i have a feeling the VX injectors are REALLY smaller than normal honda injectors. 180/190CC VS 240CC's.
i seriously hope this is the deal.. like i said.. im going on vacation, but you know i'll be right back on it once i get back.

Re: (Built B16A)
ok, i called and spoke with the parts manager, and also the service manager and got no love for finding the injector size of ANY honda injector. (ive also looked in the helms.. even they don't show CC value)
but, i found a few numbers to throw at you guys.
injectors..
06164-P05-A00 = VX and the CX
06164-P06-A00 = Si and the DX.
now.. intake manifolds..
CX 17100-P05-A00
DX 17100-P06-A00
VX 17100-P07-A00
Si 17100-P28-A00
O2 sensors..
CX 36531-P05-A02 ( 1 wire???)
DX 36531-P2R-A01
Si 36531-P1H-E01
VX 36531-P07-003 (5 wire NTK L1H1 wideband O2)

Re: (Built B16A)
here is some helpful info. I had a 93 cx and i swapped the intake manifold out to a 94 ex manifold. It came with the ex injectors so i said cool i just leave them in. The car ran unbelievably rich. so rich that it would poor black smoke and stumble. so i went back to the cx injectors and it ran fine.
so from there we know CX injectors are smaller then EX injectors and if CX and VX injectors both have the same part number then we can conclude that the VX injector is indeed smaller and most likely the cause of your problem.
So i would go back to your original wiring plan (the one with no CELs) and drop in some known 240cc.

Re: (Built B16A)
I just repinned a VX engine harness to fit in a DX chassis yesterday. I removed 12 wires. From past experiences with other Honduh stuffs, I can assure you that the wrong input on the wrong pin when you do the old ECU swap into a car with different wiring makes the car run fucked - EGR position sensor input on the HF's cause OBD0 PR4 to claim PA sensor dysfunction, and the clutch switch input on the same platform causes idle to raise by 500 rpm. I'd be inclined to think that OBD1 is the same - the P07 is a pretty wierd item, totally different from the rest of the OBD1 Civic/Integra ECUs.
Sort your wiring.

You're complaining about a lean run condition, without ever trying to tune the fuel maps? You are aware that the 16 bit fuel maps in Ubercrap are a step beyond the 8 bit stockers, and they don't run the same?
As far as your idle surge... there are only a handful of different IACV and code pairings that complement them. If your idle sucks, play with the IACV slider to get the PWM correct. That's what it is there for.

you have to understand.. maybe 2 hours on the diagnose.. not long at all.. i just chipped the ECU, ran a stock basemap with boost, and gave it a whirl. this is all after installing a 4 wire O2.. **** still didn't seam right, and after 30 seconds or so... really fell off the lean side.. 20+.. it wasn't right.

its funny cuz.. with the P07.. idles are fine. around town and pulling to lights. no surges. although when comming to a light, or miss start (clutch in, with gas) the idels raise, and then hesitate to fall down, the P28 symtoms are totally differant. this is almost like a vaccumm leak, but only on the P28.. hehehe.. its weird.. but with correct fuels.. it idles fine, with no vaccumm leaks.
i just got in my DSM 450s.. and i have a resistor box.. so if i can't get my hands on a set of Si/EX injectors, i'll be forced to step it up and go with the bigger injectors.. i'll keep you posted.

Forget the 240cc, they aren't big enough. Go ahead and install the 450's.
And don't forget the wiring! Pinout continuity tests from eact sensor/actuator to the ECU plugs takes less than a half hour if you can sucker a friend into manning the ECU plugs and testing what you ask for.

Re: (J. Davis)
i still haven't forgoten...
i just got my smog in the mail for the hatch, so early this week, i'll prolly go stock, smog it and then start messing with this P28 again.

Re: (Built B16A)
You know, another idea is a greddy blue box.
Thats what i'm going to be going with soon. What it does is, as soon as it sees boost it throws the stock injectors (240cc's) into open loop and dumps the max fuel into the motor (170ish HP). You can use the stock p28 ecu, and not have to **** with trying to do an uberdata map. The problem with a P28 is, that your car is only running on one exhaust valve until 5000 RPM...which is BAD...you want that VTEC point as low as possible to get the 2nd intake valve to open early. Use a stock p28 uberdata map with the VTEC crossover as low as you can...and then try using a blue box.
BUT, since you have the 450's now, set the VTEC low, and try and make an uberdata map that will work for ya. Good luck.

Re: (BauleyCivic)
im going to give the uberdata a shot.. if anything, i will finaly hav a P28 running in my VX.
im also kicking around the idea of running the VTEC sol. hot on key, and running a LS bases NON VTEC map.. at this point, im not realy interested in fuel ecconomy.
