Hi i came across this and though it might be useful to you guys out there.

Emissions Testing
The IM-240 Test
The emissions testing currently used by the EPA and RTA here in NSW Australia is what is known as the IM240 test. This is a test whereby your car is driven on a dyno over a simulated road course for 240 seconds (hence the name), and the emissions levels are collected and analysed. The road course is designed to cover the most typical uses of a car in normal use. The three gases that are currently tested for in Australia are : THC (Total Hydro-Carbons) which is generally unburned fuel or oil, NOx (oxides of Nitrogen) a pollution gas adding to acid rain formed when combustion temp is too high , and CO (Carbon Monoxide) a poisonous gas formed when too much fuel is burned.
There are many reasons why you may need to present your car for this test. Some people need to prove ADR (Australian Design Rule) compliance to be able to register their car. Some need to pass this test for engineering modifications to their car, and some do the test because they were "defected" by the police, EPA, or the RTA. If all of your modifications are done correctly, it is generally not too difficult a test to pass. Bare in mind however, that the levels you need to pass vary depending on the year of manufacture of the chassis and / or the motor. These levels are listed below.

There are currently two RTA centres here in New South Wales where the tests can be carried out. These are Botany in the South of Sydney, and Penrith which is around 50km west of Sydney. When you arrive for your test, the officer will take your car inside the building, do an identity check, and connect the car to the dyno and the equipment. You will be asked to take a seat in the waiting room where you can observe the test. Generally they will do two tests, as two concurrent passing tests are require to be considered a pass. After the test is completed, you will be presented with two sheets of paper shich show the results, and you will be told if it passed or failed.
Hitman Injection Tuning has years of experience preparing and presenting cars for this test. If you have tried many times to pass, and think it is impossible, give us a call and it can be arranged to have an inspection of your car, and we can discuss the costs involved in getting it fixed correctly. We handle everything, from the tuning and any repairs required, down to presenting your car for the test. All you need to do is drop off the car to us, and pick it up later with your two passing papers.
Below is a sample of what we can do. First there is the test paper a customer provided with his Subaru WRX MY99 on the left. From the results and the table above, it can be shown that it failed quite badly. The car needed some repairs, and proper tuning of its engine management (Haltech E8), and a sample of its next test can be seen on the right. Obviously it passed, and very easily at that. It also drives completely fine, just like the day it left the factory, and did not need to be "leaned out" as is the common misconception. It just needed the right settings, and some repairs to some mechanical parts that were not functioning properly. The dotted line on the graphs is actually the road speed of the car on the dyno, and not the gas output. The emissions lines are the heavier ones underneath. The second test levels were low enought that they almost dont register on the graph!

From this page we can see that all three of the tested gases failed. The required amounts can be seen above in the Yellow area. On the page you can see it is a Subaru WRX 1999 model, so it is required to meet ADR 37/01. The THC levels were 1.16 around 5x the required levels, the NOx was 0.90 almost 2x the requirement, and the CO levels were 16.9 over 8x the required levels. You can see why this particular vehicle was defected by the authorities.This page is one of the two passing tests that Hitman presented the car for after repairs. All of the levels are almost below measureable limits. The THC is a remarkable 0.01 which is 1/26th of the requirement, the NOx is down to 0.04 which is almost 1/16th of the requirement, and the CO is 0.1 which is 1/21st of the requirement. These levels are in fact so low, that is passes all known worldwide requirements for the most current vehicles, and future possible requirements!
