wtb 1996 vtec ecu

sorry, but i dont know where to post this.

I need this to complete the obd 1 to obd2 conversion. I am putting an h22a in my 1996 lude. If anyone can help me with this on finding one or selling one, please let me know. thank you

Also, if anyone has a factory service manual (helms) for a 1996, let me know a price. thx

hmm i'm not sure about your first question - I *thought* 96'ers were all obd2? yet you're saying you want to convert from obd1 to obd2? maybe i'm all backwards and in 96 they released both obd1 and obd2 versions in any case...

this site appears to have manuals, it's not for a 96, but for a 93 it might help, download at your own risk/intent of course. format is pdf. dunno if it's what your after because reading off of a screen really does suck ass, and by all accounts it's not "factory".

As i said in the post, i am doing the swap for the h22 and it only comes with the obd1 ecu. I would need the ecu from a 96 vtec prelude to make it emissions legal.

Thank you for the link, i will check it out. :)

Yes, all 4th gens come with the obd2. As i said in the post, i am doing the swap for the h22 and it only comes with the obd1 ecu. I would need the ecu from a 96 vtec prelude to make it emissions legal.

my 4th gen isn't obd2, it's a 92 mind you - but it's 4th gen and it's definetley obd1.

I guess a harness adapter to obd1 wouldn't work either eh? as far as emissions goes? cuz of that second o2 sensor or something.. meh, sorry just trying to help...

i put the information about all 4th gens being obd 2 in error. i went to fix it and my computer froze. So i got stuck with that there. sorry about that.
I know they have both obd1 and obd2.

Here is my problem, let me start over. I have a 96 lude, its obd2. I bought an h22 swap that is obd1. I know i can use a jumper harness, swap a few wires around and be able to use the obd1 ecu and what not. But since I will eventually have to emmision my car again, I would rather stay obd2 which will require an obd2 ecu, out of a 96 vtec lude. So that is why i am trying to buy this ecu for. I heard you cant use the 5th gen lude ecu's due to the immobilizer. Anyways, thanks for the help.

hey no worries - just trying to help ya out - you wouldn't happen to know the honda designation (ie: pXX) for these ecu's would you?

You're right about not being able to use the 97+ ecu's however - not only because of the immobilizer but also because the injectors are saturated instead of peak and hold like they are on the 4th gens. (or atleast like they are on the 4th gen jdm h22a)

i'll keep looking around the net.

P14 is stock for h23, P13 is stock for h22. 96 vtec ludes are OBD2 and use p13.
Here's a thread for you...

if that's the case there must be a way to designate an obd2 p13 from an obd1 p13 in the numbering system honda uses - and that would make it easier for buddy to search ebay/put in an order with the wreckers to track the right ecu down.

this guy is selling one...

probably more than you want to spend, but they seem sorta rare....i want his egr valve.. but I currently lack motivation to spend money.

how can i tell if my 4th gen is obd1 or obd2?

how can i tell if my 4th gen is obd1 or obd2?

as far as I know any 4th gen 92 - 95 = obd1
96 = obd2

whats the difference in the two??

History and Technical information about OBD

OBD was first introduced to the North American market in 1992. The first version is commonly
referred to OBD1. This configuration lasted through the end of the 1995 model year. Fuel injection
became commonplace in Civics starting in 1988, though the Si versions of the CRX and Civic had
fuel injection as early as 1985, and was introduced in the Integra with the launch of the 1986
Acura line. Before 1992, there was little if nothing in the way of on board diagnostics in the ECU.
The 1988 to 1991 is commonly referred to as pre-OBD or OBD0 (the 0 meaning no OBD).

Starting in 1996, OBD made some big advancements and was now referred to as OBD2. It now
became apparent that emissions had to be cut, and maintained at reduced levels for extended
mileages or periods of time. The ECU now monitored the crankshaft speed to see if fluctuations
occurred that would point to lean mixtures or a failing ignition system. It also monitored the
efficiency of the catalytic converter via a second oxygen sensor mounted downstream of the cat.
This meant that those of us that wanted to run a test pipe to eliminate the restriction associated
with the catalytic converter were faced with check engine lights as the ECU would detect lost
efficiencies due to the lack of the cat, or O2 sensor failures from the removal of the sensor.
Several products hit the market that were intended to simulate an O2 sensor and fool the ECU
into thinking that the cat was still operating efficiently. Its a little known fact that the check engine
light for the 2nd O2 sensor, or for the missing cat will not lead to the ECU operating in "limp
home" mode. It just simply leaves a glowing light on the dash to annoy you. OBD2 also added a
pressure monitor in the gas tank to insure that the pressures were building normally inside the
tank to indicate a properly closed gas cap and normally functioning evaporative emissions control
system. In 1999/2000, the connections on OBD2 ECUs were moved around, making them
completely incompatible with the 1996-1998/1999 chassis and ECUs.

Though the ECUs from the JDM 1996 and up cars appear identical to their North American
counterparts, they are very much the same as the USDM OBD1 ECUs in their operation, lacking
the crank speed fluctuation and fuel tank pressure sensors, as well as the 2nd O2 sensor from
the USDM OBD2 cars. This makes them ideal for those wanting to run the JDM ECU that was
supplied with their 1996 and up JDM engine swap in their 1988-95 car. For those of you ambitious
enough to try and use the North American OBD2 ECU from your 1996 and up USDM swap, look
forward to lots of extra work incorporating the fuel tank pressure sensor, as well as the extra O2
sensor or one of the many O2 sensor simulators on the market.

One thing to keep in mind anytime you are swapping an engine from a different generation of
engine management into your car is to stay with your existing engine wiring harness. It is always
100 times easier to make the necessary mods to the engine harness that came with your chassis,
then it is to make mods to the chassis harness to match the engine harness.

---------------------------------------------
that being said - a lot of people (who mod) prefer to run obd1, so they buy a jumper harness, then they can get rid of the second 02 sensor, and some other hassles that obd2 enforces.
The problem is when these people go to get emissions checked - if it's a place (ie: cali) where they use more than just a sniffer - and they try to
"hook up" to your obd2 with a scanner (because these guys are by the book remember - they'll look up the year of your car - and then say "oh this one is obd2" and out comes the scanner) - and if your running some harness to an obd1 - it's not going to scan anything - and you will fail emissions. I assume that's why the poster of this topic wants to keep his car legal - so he doesn't have to go thru these troubles later down the road. Unfortunatley for him (and honda at the time i assume) the 96 prelude happened right on the boundary of honda's model change, so he's left looking for a somewhat rare ecu, especially if it's vtec, because i imagine 96 vtec's are still in high demand - plus you have the accord community dropping h22a's and wanting to stay obd2 as well.

hope that helps...

thanks man

hey, sorry i was gonna get back to your question ludeguy about which ecu that is. I see the question has been answered. I appreciate your input ludeguy, and your help is seriously appreciated. :)

i emailed that guy, hopefully he still has it. :)

hey no worries - i've been bored lately (;

best of luck with the purchase - hopefully he hasn't sold it yet.

actually, he was holding it for a friend of mine and sold it an hour later to someone else. they really needed it. i tried to email him to see if he still had it but the email address he had is no longer valid. :( it sucks. and i cant believe that he did that. oh well.

yeah that is shitty for real.. bad way of doing buisness - agreeing to sell something and then selling it to someone else.. i'll keep my eyes peeled for another, your best bet is prob to check out all the "for sale" or "classified" sections of all the different honda sites.. because i haven't seen many p13's specified as obd2/1996 on ebay in the past. you could also talk to a jdm reseller in your area to keep their eyes open or use their hookups with the scrapyards.

best of luck.

You know i really appreciate your help. i have searched everywhere. i actually emailed a dude from ebay who was selling another ecu, and he told me he has the one i am looking for. i have searched all the lude sites, even the search engines, junk yards online, and i have yet to go to a junk yard in person at this time. my motor has arrived today but the delivery dude is being an ass about it. long story. so this has definately been an experience. when i look for the ecu i put in the p13 obd2 and i only referred to it as the 1996 vtec lude cuz i figured that would have made it easier. i will just stick to the p13 obd 2, i have better luck there. Again, thanks a bunch. Even tho that dude flaked out, which really sucked, you still pointed me in the right direction.

hey it's great helping out where I can... I hope this latest problem with the delivery guy is the last of your swap problems. Unfortunatley for me - my swap was an absolute nightmare, if you search around these forums you'll probably be able to recount most of my horrors, sadly, it's not because it's a hard swap at all - it's because a lot of people in the automotive industry are absolute assholes who want to rip you off. I would have loved to work on my own swap myself - but my car never made it back to the island that i live on, so I had to sort of micromanage it from a far - utter nightmare - i'm getting chills just thinking about it again. the thing about swaps is the hidden costs - and that you can't blame on anyone - it's just not always as simple as a "new ecu/new jdm" theres stuff to go along with it - if you really want to do stuff right, including new timing belts, waterpump, etc not to mention all the other stuff that pops up along the way.

best of luck (:

thanks man


you sounds like you really know what youre talking about.. are you ASE certified?

The connectors ~ the difference in OBD1 and OBD2 (physically, on the outside) are the pin connectors. They are shaped differently.

Hello I have a question I am swapping a 2.2L SOHC out of a 1991 Honda accord and I am putting in a 2.2L SOHC VTEC out of a 1996 accord and am getting the engine,transmission,ecu and wiringharness what do I need to complete this swap
