Heres the catch, its a 1996 Honda Integra Type R from Japan.

I need a scan tool to be able to read the car to be able to pass inspection so I have a bunch of questions.

Anyone know how to go about doing this? Will a USDM ECU solve the problem? Why can't a scan tool read the car? Is it the JDM ECU or something else in the car. Is there a way to get it to read the car?

Any info would be great. Thanks

When my friend registered his rhd itr, the dmv made him exempt from all emissions and inspections.... Dont know why Does the car have the port to plug the scan tool into? Try a USDM ecu.

NY does not allow exemptions. The car MUST communicate with the scan tool. If it cant communicate and you spent over $450 to try and fix it and it still wont they exempt you for one year. The next year you have to do it again. I am not spending $450 a year for inspection.

It does have a port to plug into.

One other questions. Is a 1996 JDM ITR OBDII? Didn't japan not switch until 1998 or something?

 

i would definitely start with a USDM ecu. that's the most logical step to me.

 

Well I can swap in a USDM P73 ECU but then comes up these questions

If I put in a USDM ECU into a JDM ITR is it going to throw codes? The sensors and emissions stuff is different on JDM engines right? If i can swap ECU's and not gets codes so they can read the car then I would be done but I have heard the oil pump CKFS pully and sensor, secondary 02, EGR valve, VTEC pressure switch, Knock sensor and coolant switch are all different in JDM engines.

Will this throw codes or is it plug and play?

 

it will throw codes for the parts you mentioned...

if you have it registered as a kit car, i thought there was only the safety inspection and not the emissions...

 

It is not registered as a kit car.

So I need USDM

P73 ECU
Oil pump CKFS pulley and sensor, (CKFS, What is this? I found it in a search.)
Secondary 02,
EGR valve,
VTEC pressure switch,
Knock sensor and
Coolant switch

Anything else?

 

usdm itr intake manifold, usdm itr cat for 2nd o2 sensor...there was a thread on how to convert your jdm itr motor for us spec to pass bar. ill try and find it for you...

CKFS is Crankshaft Fluctuation

Fixed that for you. A '96 spec JDM ITR does NOT have the DLC ( Data Link Connector) which is what they use to scan the ECU, not the little plug by the ECU where you can stick a paperclip into. In addition to not having that plug, the car does not have the bracket for the DLC. The plug must be in the bracket or the emissons people will not even touch it. Now what makes this difficult, is that you can not buy this bracket from Acura. It is a piece of stamped metal welded to the support bars underneath your dash.

You can run a USDM ECU, but if you are planning on using and ITR ECU it will have to be one from a '97. In '98 they added the gas tank pressure sensor which is not on the 96 Spec, so it would through a code. If you go with a GSR then you can use a 96 or 97 ECU, but that may throw a code for not having whatever additional pieces the GSR may have. (I have never tried that route, so I can't tell you for sure).

You will need to wire up the Secondary O2 sensor b/c of the USDM ECU. Though you can keep your stock JDM cat on if you use an O2 simulator. If you don't have a simulator, then I'm pretty sure that will require you to drill the proper hole through the floorboard in order for the O2 sensor wiring to pass through (I never really tried to fit the secondary O2 sensor through, since I had a simulator)

You will also need to wire up the crank fluctuation sensor and the VTEC oil pressure switch. These two things will require you to change out some parts on the car, such as the oil pump, the VTEC solinoid, and add the CKF sensor itself. Though these two things can be bypassed by jumping the wires with other ones.

Basically what you are going to need to do is completely rewire your under dash harness to begin with. You will have to get another harness from another USDM OBD2 car preferably a 96-97 GSR or 97 ITR. Then you will have order all of the helms manuals for a 97 ITR, to include the electrical one b/c they all contain all of the bits and pieces to the puzzle.

A USDM cat will not work on your car unless you change your header/manifold out to a US spec one with the 2 1/4" collector. Then you will also have to change out your exhaust B-pipe, as the JDM B-pipe is longer than the USDM one. It will just be easier to have a new cat made to the length that you need with the bung welded on for the secondary O2 sensor.

Now the intake manifold, this is the first time I have heard that you need to change that out. What would be the reasoning?

 

can you post a pic of the plug on your ITR

or you could cut the flange on the front of the cat and have the 2.5" welded onto it. i read that there is a nipple needed on the IM that the usdm and the jdm doesnt. i cant find the tread on how to make your jdm b18c legal...

 

Great technical info Nolan.

it was meant for turbo em1 .. just want to see what plug he has to use a scan tool for.

 

this all depends on how you want to do it. properly or what ever it takes...

CKF - easily bypassed
secondary O2 - simulator and resistor to bypass
EGR - USDM ITR has EGR??? (not any I've ever seen)
VTEC pressure - easily bypassed
knock sensor - JDM knock sensor works fine
coolant switch - ??? there's one missing on a JDM ITR?

EVAP solenoids and the port into IM wasn't mentioned. can't really bypass them easily.

if you want to do it right, hold your breath and dive in... https://honda-tech.com/zerothread?id=906684

 

ok thanks for all the info.

I am going to try and dive into this. Now I called up the inspection place and here is what they are telling me.

They said the ECU has the VIN number in it. (I know it does NOT have the VIN but I have heard it has some sort of ID number in it). For example if I have a 1996 USDM ITR and it passes inspection. Then if I put that USDM ECU in another car when they go to scan it, it will come up with the same ID number and will be seen as a red flag since it should be only in one car but it really comes up as two different cars with the same ID number and that looks fishy. The guy at the inspection place is saying even if I convert the car there is an ID number the DMV will see from whatever USDM ECU I buy.

So before I spend a ton of money on parts, is there a ID number in the ECU to distinguish between cars? Say you scan 5 different USDM ECU's can they tell which is which? Can they even tell the difference between a P72, P73, P74, P75, P2N, P2P, P2E, P2M, P2T ect...?

scanning the ecu won't give out any info. thank you honda haha. vin #'s don't show up on 96-00 civics and integras.

I know there are no VIN's but he is insisting there is a ID number of some sort when scanned and I want to be sure. Thanks

Yeah that can be done, but you will have to get it shortened at the same time too.

The nipple can be bypassed by T-ing off of another vacuum line.

There is an ID number on the ECU. Though you shouldn't have a problem if you buy an ECU off of someone else b/c ECU's go bad all the time and they will need to be replaced.

In or on? I understand there is a number written on the outside of the ECU but is there something in the ECU that is electronically transmitted to the DMV?

What if there is? so what? I know NY sucks with this scan thing but just borrow an ecu, It wont make a difference. as long as there a no codes and its in the ready mode it will pass. Who cares if the dmv thinks something is fishy later, you'll already have the inspection sticker and will be on your way.
