I plan on boosting my 98 coupe this spring and was gonna run a chipped obd1 ecu with a jumper from obd2 and have a cat and a o2 bung on the down pipe..when it comes to inspection time i wanted to put my obd2 ecu in just for the inspection...now my question is does anyone know if i will throw any codes as long as i have a primary and secondary o2 sensor? thanks in advance

 

it souldn't throw a P0420 code (cat effieciency) but i'm not sure the oem computer will like the boost. so i would turn the controller all the way down.

 

if you change injectors for the obd1 ecu, you will need to change them back too.

 

i plan on running 10-12 psi so that means i need to get a 3bar map will this throw a code also?

 

you could always put a resistor on the O2 sensor. The obd2 ecu wont like the 3bar map, it wants to see what its programmed to see, anything else it doesnt know what to do so it trips the code.

 

I plan on doing the same thing this spring, and im also from ny. Now if ur running larger injectors then ur going to have to swap ur stock injectors back in, with ur stock ECU. Ur going to have to have 3 out of 4 readyness codes ready which wont be because u just took out ur ECU. Your going to have to drive around for about 10-20 miles to get the codes ready in order to pass. During this time have both O2's plugged in and stay the hell out of boost. ( lower boost as much as possible, take out wastegate spring whatever does the job)

 

what codes will it throw?

 

It shouldnt throw any codes if u have both O2's, stock map, stay out of boost, and have a good cat... I mean is ur car had a code before u boosted it or it wasnt running right then dont expect for that code to magicaly disappear because u took the turbo off. Just double check before u go to get it inspected. I would also recommend getting a code scanner which tells you what readyness codes are ready. I have a actron scanner and there well worth it. So u dont end up going there and only 2 out of the 4 r ready of something stupid like that happens and u fail.

 

yeah theres nothing wrong with it now its pretty much stock and i have no codes so hopefully ill be good.

 

sorry posted on a friends name again

 

Ever thought of yanking the CEL bulb?

 

would be good but the car is a 98 and in ny it has to be plugged in to the computer

You'll fool only a visual inspection, but like stated above the car will be plugged in and information will be sent from your car to the inspection computer and if the vehicle has any codes it's an automatic failure.

In NY, OBD1 vehicles are tested on the rollers. OBD2 cars are plugged in.

I Purchased this OBD2 scanner, checks IM readiness and deletes codes.

 

my friend has a new inspection guy......sends him a copy of the reg and $100 and a sticker is sent back.....don't know how, but it works lol so look around im sure it can be done, worth the $100 a year instead of going through all that trouble

It can be done for $42 a year...

Not to mention the CEL not coming on briefly when the key is turned on is a failure in itself.

So how is it tested? I guess it's just the city then.

A 1995 or older model year vehicle, or a vehicle that weighs 8,501 lbs. or more is required to have a high-enhanced emissions inspection if the vehicle:

-Is registered in the New York City Metropolitan Area (NYCMA), and
-Is not exempt from emissions inspection.

Vehicles that have a model year of 1981 or newer and a weight of 8,500 lbs. or less must receive a dynamometer test.

No inspection stations anywhere around here have anything resembling dynamometer testing... :shrugs:
