Re: d15b stage 3 HELP!!!
I have no chouce but to try and make this swap work ..so far I got I can use a p2p auto ecu or use a p28 auto ecu to make my tranny shift right and I need a ex harness obd1 or obd2?? And wire in the vtec?
Re: d15b stage 3 HELP!!!
ure in california the fn capital of honda motors. how many junkyards you have to go and get a d16z6 swap from?

Re: d15b stage 3 HELP!!!
so do you actually have the 3 stage vtec motor? or just d15b vtec.
theres 3 differet versions of jdm d15b post a picture of your actual motor with vtec solenoid visible...
d15b vtec engages at 4800 ecu switches from low cam maps to vtec maps
d15b 3 stage first vtec engages at 3000 rpm and then next at 6000 rpm
and needs 3 different maps for each lobe.
it will be just stupid to run it with stock p28 ecu and expect it to work properly
3 stage operates in 12 valve mode untill 3000 rpm..
just read the damn wikipedia and you will understand how much time you will be wasting trying to get this to work...

Re: d15b stage 3 HELP!!!
The thing is that engine is already in my civic ...Probably could get one frm the junk yard but I don't trust motors...and I do have a 3 stage d15b I should of got the obd1 d15b
Re: d15b stage 3 HELP!!!
yep well find an ecu for it on ebay and add the missing wires. it will be much better than running a p28 ecu
otherwise you can get it tuned with Neptune or hondata they have outputs and secondary maps so you can use them for the second vtec engagement
the time you spent asking here you could have a high chance of finding someone who would trade you for a running z6 motor so you can swap it and not worry about it

Re: d15b stage 3 HELP!!!
OP, regardless of whether the engine is already in the car or not your best bet is to pull it and find something else. For serious.
What you're doing is the definition of leaping before you look.
It won't run right on a P2P or P28. The correct ecu is a P2J which is OBD2 which 1) isn't compatible with your auto trans. 2) will not communicate with the states scanner which is an automatic fail.
I've been to your states CARB, BAR and STAR sites and downloaded a **** ton of info in the past to try and help people in Comyfornia.
If you got this thing in and half *** running here's how it going to go down when you try to test.
They're going to do a visual inspection first. When they get under the hood they're going to ID the engine so they can make sure all of the emissions equipment is hooked up.
The problem is THEY WILL ID IT correctly and know it's a 96-up (OBD2) engine. They're familiar with block stamps and casting codes. The technician even has a nice little data base to put info into and can pull diagrams showing where thing should be and what they look like.
In your state when you put an engine in from a newer diagnostic version (you're going OBD1 to OBD2) EVERYTHING that is related to the emission controls for that diagnostic version has to be in place and FUCTIONING.
What that means is you would basically have to convert your car to OBD2 including the DLC port for them to plug into. On top of that they still probe the tail pipe to read exhaust emissions on newer vehicles unlike other states.
With them analyzing exhaust gas your not going to get away with a half assed way of running the engine. There is no US equivalent ecu to run this engine properly and any ecu not from the states won't communicate with their machine.

Re: d15b stage 3 HELP!!!
In the state of california, you can run the obd2 engine in obd1 chassis. Yes
You just need to convert it to obd1 spec/ sensors. This is incorrect unless they've slackened the laws in the last year which I doubt. They generally amend them every year and make them more strict.
You are not allow to run an older engine then the car. Ex: i owned a 93 civic, i can't put an 89 d16a6 in my 93 civic. That won't pass visual. Right
Just thought you should know.Maybe you should read their regulations, I have.

The way it reads (improv) is that replacement engines must be the same year or newer, be functionally the same and have been originally available in the chassis in the state of Ca. or the US.
Technically the D15B was never offered anywhere in the US. A non vtec OBD1 US version would be the D15B7.
Functionally their the same, technically by Ca. law their different because there was never a D15B available here.
Some locations overlook this and run it through as long as everything else checks out. Some automatically fail you because of it. In most cases you can drive down the road to another station and get passed.

Re: d15b stage 3 HELP!!!
You sure? there might have been an 93 civic 2 door with a d15b and a chipped ecu from factory to adjust for emissions
Ive seen one at the junkyard and got the ecu from it.
I looked allover the engine bay and it seems like the engine is original
Ita only that specific year/model
Its possible some of those cars made their way in california also
If they did you might have a chance

Re: d15b stage 3 HELP!!!
You're trolling right?
All US and CDM engines have a 5th digit on the engine code. As far as I know the Euro, African and South American markets plus others are the same, have a 5th digit.
The only ones that don't are the Jap.
There are early OBD1 ecu's that have been found with factory installed programable eproms. That has nothing to do with what engines Crapofornia allows you to use and how you have to do it.

Re: d15b stage 3 HELP!!!
No i dont live in cali i saw the car at junkyard with d15b vtec and the factory eprom chip
From what i red they had to revise the programming to comply with emissions
I dont know if early 93 civic came with that engine. There might be a possibility
i looked everywhere in the engine bay for signs of the engine being an import and not original but everything was there there was no markings and it did have usdm vtec solenoid with pressure switch
I was surprised too. Its possible that they just did a really good job at swapping and installed everything properly etc.

Re: d15b stage 3 HELP!!!
If you can provide some kind of documentation showing otherwise I'd be interested.
Re: d15b stage 3 HELP!!!
ill see if i can find the article again
in any case theres only few possible reasons i can think of why honda would use a modified ecu in factory car especially since not every car is like that
1 to adjust for emissions or specifically for california emissions
2 if they for whetever reason had to use a jdm engine and change the maps for higher compression(maybe shortage of engines or recalls i donno)
3 it makes no sense if they all had a z6 motor and only some would be chipped and others with same motor would be running stock p28

Re: d15b stage 3 HELP!!!
From what I understand your emissions option is the answer. These factory chipped ecu's are early OBD1 and are rare.
I stand by the 5th digit on the engine code unless proven otherwise. In the 70's and 80's there were 5 digits, following through to current date.
There's no logic for a short lived 4 digit engine code in the US in the early 90's when nothing other than emission standards changed. Besides logic, what proof is there of ANY 4 digit engine code being available in North America? The only thing emissions "changed" was the diagnostic systems of the ecu and the supporting electronics/sensors.
This is derailing the OP but I'm all in for supporting info to the contrary if it's out there.

In the state of california, you can run the obd2 engine in obd1 chassis. Yes (I know)
N*werk: You just need to convert it to obd1 spec/ sensors.
NUB:This is incorrect unless they've slackened the laws in the last year which I doubt. They generally amend them every year and make them more strict.
"The way it reads (improv) is that replacement engines must be the same year or newer, be functionally the same and have been originally available in the chassis in the state of Ca. or the US."
N*werk: same thing that i said, car is obd1 so the Obd2 motor has to be running obd1 sensor)
You are not allow to run an older engine then the car. Ex: i owned a 93 civic, i can't put an 89 d16a6 in my 93 civic. That won't pass visual. Right "I know"
Just thought you should know.Maybe you should read their regulations, I have. -"I just read alot and learn" LOL
NUB: To add, technically JDM engines are no allowed. The way the law is written it has become a gray area and up to interpritation by the inspector.
N*werk: Wrong, please update yourself. Taken from http://www.arb.ca.gov/msprog/aftermkt/replace.htm "Japanese Replacement Engines
Used engines imported from Japan can be used as replacement engines as long as the engine being used has been identified as functionally identical to the original engine. Please refer to the engine importers catalogue to determine if a replacement engine is legal for installation in your vehicle."
The way it reads (improv) is that replacement engines must be the same year or newer, be functionally the same and have been originally available in the chassis in the state of Ca. or the US. - I already stated that. *_*
Technically the D15B was never offered anywhere in the US. A non vtec OBD1 US version would be the D15B7. -Can still use it to pass smog
Functionally their the same, technically by Ca. law their different because there was never a D15B available here. - Can still use Jdm engine
Some locations overlook this and run it through as long as everything else checks out. Some automatically fail you because of it. In most cases you can drive down the road to another station and get passed. - "Duh"

Re: d15b stage 3 HELP!!!
yea the only one i can think of is having it for early california emissions.
because having a chipped ecu and non chipped ecu all other states makes no sense.
why would they randomly put that in the car with d16z6 and not put it on another car with d16z6
could swap the jdm ecu internals to a p28 case i dont think they would go as far as opening up the ecu to look for a chip or do they?

Re: d15b stage 3 HELP!!!
If the vehicle is a California certified vehicle then the engine must also be a California certified engine.
which still means none of the jdm engines can be used since they are not identical.
they all have higher compression than usdm versions...
it is a grey area

oh boy u re a dumbass.
its been confirmed that there are chipped ecus from factory
i have one
do some ****** research before opening your mouth next time

this is not GDD stop acting like a dumbshit and posting stupid replies this is a discussion forum not a popularity contest like GDD section)

says the guy that just argued about non existent factory chipped ecus when theres plenty of proof with pictures lol still a dumbass and a stubborn one too.
