emmissions on a 1jz-gte 1984 ma61

ok, I've heard so many comflicting stories about waht will be required of my emissions test, I'd like to know the facts.
Some people say that all I have to do is pass the 1984 laws, as that's what the car came with and if I'm running cleaner than that, I'm fine.
Others say I have to pass the laws for the year the 1jz was made, and other say I have to pass the 2003 laws.. can anybody help me?
I need to know, because if I have to pass todays laws, I cant put the microtech in until I get it emissions passed
also, any contacts where I could get this (and engineering) done would be muchly appreciated

I just told my engineer my 7MGTE came out of an Australian spec supra then he didn't even require an emissions test. He asked if I was sure and i said yes, it was out of my uncle's smashed supra.
I had the microtech on it when i got it engineered so I just put the Air flow meter back on and cable tied the wires down inside the quarter panel, just incase he knew 7mgte's have AFM's. 1J's dont do you dont have to worry bout that. 
I don't know which cars came with the 1j through the normal "Australian delivery" door. I thought all 1J's were "imported" only. If a car was imported it hasn't really passed the ADR emissions tests. That why an "Australian delivered" car is better to use as a donor. The engineers and EPA are sceptical because of the tuning in the ECU. (Like the S15 in Jap has 187KW and Aussie has 147KW and they're identical physically)
Avoid emissions test at all costs.
Factory ECU's wont pass on an engine that has done over like 40k kms. 
There are a whole lot of tests your car has to pass. You will get knocked back, and will be forever going back to the Botany or Penrith testing station trying to get it passed. The morons at the test station will tell you to replace this and that. You spend shitloads of cash, come back and it still doesn't pass, then they take another guess at what is causing the emmissions and tell you to replace that and so on........
With a microtech, you have 4 eeprom locations. If I ever have to get emiisions tested i'm going to use the third location strictly
for passing this test. (First=full power, second=economy) Then you just tune this memory location for a/f ratios dead on 14.7:1(stoichiometric ratio which is the excact ratio to ensure all particles of are burnt effectively with the least emissions)
It's very easy to do this cause they just free rev your car at 500rpm intervals up to 3000rpm apparently. You can set your values in the MTX for those rpm bands and how much fuel you inject and its easy. 
My engineer is in Rydalmere(near ermington) costs me $440 incl GST for full engineers report. PM me if you want the details

but to get the car engineered and registered with a 1j, I will pretty much have to get it emissions tested wont I?
hrm, in that case I'll put the ltx-12 in straight away, and see waht happens
so your supra passed engineering with no tacho?

There is no law saying your car has to have a tacho because it isn't vital to operating the car.

Yep as frankie says, it passed without the tacho. They do a decibel test at 3000rpm so we just guessed what rpm and it came in at 89 decibels at 1m from tailpipe.
If anyone has had succes with wiring a ma61 tacho pls give it up!

I have a feeling you just need a 3x signal booster. I haven't looked at the wiring too carefully yet, but that looks like it would work. I'm going to ask advan if they know anything.
do you know how to tune the microtech ecu's paul? 'cause I have rego coming up in a few months and ideally I'd like to get engineering and emissions done before that, so I dont have to go through all that twice

what?!? as far as im aware the japanese have much tighter emissions standards than us, using a standard ECU at an emissions test should not be a problem, as far as im concerned the standard ecu will pass the test better than aftermarket one as the engineers who program the ECU's do have an emissions agenda and they stick to it.
ask anyone whos had an emissions test with an import engine and factory ecu and cat converter im pretty sure they'll tell u that they passed with flying colours.
by the way im not saying that retuning an aftermarket ECU wont work, as a matter of fact its a good alternative.

From what I gather most of the newer Toyota models will pass, some other cars wont. Its to do with the difference in the way they conduct their testing, which produces different results.
For example, the Series 6 RX7 (not AUS version) is supposed to not pass our ADR's.

A brand new holden wont pass the new emission standards the EPA is to bring in ROB_RA40.
Japanese emissions testing is alot less stringent than ours. Did you know when they test their cars instead of checking emissions from when the car is cold(when emissions are at there absolute worst) they pre-warm their cars to operating temperature and then test them.
That's exactly why as Frankie says the new RX7's don't pass our emissions but passed Japan's comfortably.
An aftermarket ECU tuned to pass an emissions test will do it far easier than a standard ECU is what i'm also saying. Cause you can tune it with AF meter to get spot on 14.7 ratios. Standard ECU's wont ever give you 14.7 in the test situations you undergo. Because the factory ECU's want nice crisp acceleration and smoothness which comes with adding fuel and ratio's down towards 13:1(with this also comes massive increases in CO-Carbon monoxides)
For the purposes of the test, you take out all that smoothness and crisp acceleration and set it for 14.7:1 af ratios. You'll have a better chance at passing with the aftermarket than the factory.
Draven, i'm going to make my own wideband kit shortly which will be great for AF monitoring(costs around $400). Best to do the first tune on the dyno as you can measure the power increases and get the torque curve as high as possible for the longest possible length of the graph. Hornsby prestigue and performance do great tuning cheap, you gotta do it with the dyno for power purposes then you can do cruise maps etc on the road.

yeah they also do it here as well, i have 2 Em test results one with the engine cold and one with the engine warm, the bloke scrapped the 1st test after he realised that the engine wasnt warmed up. Emissions testing is starting to sound like a bit of a sham to me, the reason the RTA told me to do one is because they needed data on import engines.
AND how can u possibly think that holdens dont pass the emissions standard, its not like they are using outdated technology from the 50's or anything

Holden's wont pass the new standard emissions test the EPA with to bring in. Holden is whining to the government and have been for a while to keep delaying the introduction of new emission standards as their engines wont pass hence they cant sell their new cars. They don't like this cause they have an arrangement with GM in the states buying their old rod box V6's which were designed in the 50's based on the Rover V8(think its this one). It has the exact same bore/stroke very similar block casting but just has two cylinders chopped off the end.

Don't know if your being sarcastic there, but there technology is old. It's an old German fuel injection setup called DELCO developed in the 80's.
There are two types of emissions tests. The first one is the one that manufacturers must get their cars to pass before they can sell them to the public. This test in Japan doesn't require them to do a cold start emissions test, that's why it passes the Japanese emissions.
The other test is the one that you and I are probably familiar with. Its for engine conversions etc. You dont need to do a cold start for this one which is good cause its easier.

This is off the subject slightly but since tacho's were touched on I thought I'd take the opportunity to let you know that SIXWORKS now supplies Tacho Boosters to enable the factory tacho to be driven from the 1J's tacho output. The unit will work equally well on a host of other import engines as well.
Please email me on sixworks@optusnet.com.au and I would be only too happy to send you a pdf file on the product.

still on tachos... my LTX-12 has a tacho-output wire.. any chance this is a boosted signal wire? (the manual doesn't even mention the tacho output, except in the diagrams)

Microtech outputs a 12 volt square wave from memory whereas the MA61 tacho requires a much higher voltage to drive it. The SIXWORKS Tacho Booster Model TE-200-01 is suitable for this application.
Did you get those pdf's I sent?

yep, I did
I will buy one, but probably in a week or so. I'm trying to organise a battery and some other things at the moment

That's fine. I only asked as your email bounced the first time I sent it.
