Is it possible to pass emissions with an OBD-I motor in a OBD-IIa chassis?
I have a 97 Civic Coupe with a turbo setup.

that is a negative ghost rider the car can only have the same year or newer OBD.

 

any ideas? is there a tuneable OBD-IIa compliant engine management system?

I think AEM has a new one out for obd II cars

 

AEM EMS = $1,000+

edit: right off AEMs site "Emissions Compliance - No, Offroad Use Only".

 

bump

 

double bump. buy one get one

 

How do they test for emissions in MD? Do they just connect your car up to a scan tool and check for compliance? That's what they do here in AZ. I have a JDM B18C OBDI motor in my 99 EX Civic (OBD-IIB). How I passed was I used a USDM GSR OBDIIa ecu with a IIB - IIA jumper harness. In order for it to work I had to perform the ckf bypass trick shown here:

http://technet.ff-squad.com/ckftrick.htm.

I had no CELs and was able to pass.

For you, what I would do is pull the wastegate spring so you don't build any boost, and put in an OBDIIa ecu. Just don't run your motor hard when you go get tested.

 

yeah, they just connect the harness and make sure everything is in order.

 

As long as you can run OBD-II and have no CEL you will pass, other than that sorry about your luck. When they go to plug into the diagnostic port and it doesn't work I believe they would give you a fail notice.

 

So your saying the cheapest way for my to do this is drop a D16 OBD-II and a cat. This is rediculous I just got my motor turboed! HELP IM SCREWED

 

What motor do you have?

 

B16A originally OBD-0 converted to OBD-1 in a OBD-IIa chassis. Try saying that one 7 beers in.

So basiclly I have to keep going every 4 months and fail it + $10 a test. Those asses always burn up my clutch and rev it like crazy. Is there a limit to how many times I can fail it?

 

Burn your clutch and rev it? So you are saying that they do the roller test on your car? According to the other two posters, they say that all they do is plug your car into the scan tool and check for compliance.

If they do not do a roller test and all they do is check your ECU for compliance and pull any codes, then you need to make sure you have all your emissions devices working, (evap purge solenoid, evap canister, both o2 sensors, knock sensor, etc.), run a stock OBD2A ecu, (idk if a 2B ecu would work...), and pull your wastegate spring so you don't build boost.

They'll take your car, plug it into their scanner to pull any codes and check for compliance. If you don't have any CELs, you should pass.

If they do a roller test and sniff the tail pipe, then the only recourse may be to swap in a stock motor and ecu w/ all of the emissions equipment hooked up.

 

from the VEIP website :http://mva.state.md.us/MVAProg/VEIP/...htm#right_test


What is the Right Test for Your Vehicle?

On-Board Diagnostics (OBD) Test
1996 or newer model year vehicles weighing 8,500 pounds or less and equipped with a computer controlled engine and fuel system

Instead of testing your vehicle’s exhaust, your emissions test will involve scanning your vehicle's computer for emission control malfunctions. During an on-board diagnostics scan, a lane inspector will connect to your vehicle's computer through a connector under the dashboard to determine the presence of recorded “trouble codes” that illuminate the “check engine” light on the instrument panel. Vehicles with an illuminated “check engine” light automatically fail the emissions test.

 

Thanks for the verifying the testing procedures. Good looking out!

So that settles it. The cheapest and most headache free way of doing this would be to get a stock EX cat (I assume that you have a test pipe?) and hook up the secondary O2 sensor. You had a DX, according to your sig, so you may need to extend the secondary O2 sensor wires so it will reach the EX cat which will be underneath the car. Hopefully, you didn't remove any of your emissions equipment that came with the car. Then I would find an USDM OBD2A ecu and hook it up to your car. See if you get any CELs. If you don't, pull your wastegate spring and then go get tested. As long as you are running a USDM OBD2A ecu, have all your emissions devices plugged in and running, and no CELs, you should be able to pass.

 

When I went they put it on the rollers and then plugged in it to the computer after they moved it; that's where it failed.

Um, NO

http://www.aempower.com/ViewCa...D=116

works with obd2 vehicle will let you get smogged(scanner still works) and not throw a CEL, you would need to make a jumper harness to connect to it though. I think its like $450

 

Didn't mean to rain on your parade.

I only looked for the emanage. does that work with boost?

edit: you expletive! it only supports "## All Honda K-Series M/T "

 

No they only have a jumper for the rsx, look on their forum Im pretty sure its been used on older civics already

 

That's good information. any alternatives?

 

From the forums at http://forum.aempower.com:

"we are investigating the following for suitability of the F/IC:
Scion xA/xB
02-06 Acura RSX
88-01 Acura Integra
97 Acura CL 2.2L
98-99 Acura CL 2.3L
91-95 Acura NSX
90-02 Honda Accord (Except V6)
88-91 Honda CRX
88-05 Honda Civic
93-97 Honda Del Sol
88-00 Honda Prelude
01-05 Honda S2000
95-05 Mazda Miata

as far as I can tell they only support the "Honda Civic 01-05 (DX, LX, EX)" and the "02-05 Honda Civic Si"

I'm gonna try and search some other forums

 

I used to pass by dropping my prelude as low as it would go on the coilovers and showing up at the Frederick test site. They'd say it was too low to test and give me a 2 year exemption. This was on an 01.

with my S2000 they simply drive over the rollers. They're not doing anything with them, they're literally just plugging in a scanner and seeing if you have stored codes. You fail if you have any OR if you're running a fresh reset. That's all there is to it. You failed because they attached the scanner and got no response, as you're running an OBD1 ECU.

It's not rocket science here. Use an OBD2 ecu and drive it around for a week off boost. done.

 

Take you about 100 bucks go to the bad side of your town and throw some money around you will get a sticker.

 

Man that sucks....I live in MD on the eastern shore and we dont have Emissions insp. over here just safety. MD always has to do **** the complicated way!
