As the topic suggests...

I know theres some procedure they use to measure the noise level

90dB at 1meter back @ 45degree angle to the exhaust @ X-RPM

or SOMETHING along those lines, does anyone know?

just got a dB measure at home at registered 84dB on idle, but im aware they dont measure the noise at idle

thanx in advanced

just do what i did and bolt on the stock exhaust for the test, it can be done in about 20 mins

thats what im worried about now!!

i had a pretty sedate twin pipe (3" in 2x2"out) and it was pretty quiet, but eventually i opted for a bigger muffler

now iv put the old custom twin pipe back on and if inasnt is saying he got 83dB on a STOCK muffler (which is only 7dB away from limi), i think im screwed!

got a dB tester here, but i cant exactly rev the car and measure the back of it at the same time :cool:

have to wait till later tonight

well see tonight after the preliminary tests :S

its not looking good, had to take a fair amount of sh|t off the car already

only leaves me tomorrow (possibly wednesday before the 11am test) to get it done

this couldnt have come at a worse time (exam period)

There is a list on the EPA site of approved testers -> http://www.epa.vic.gov.au/noise/testers.asp

Any1 know how much these places charge for the basic test?

Apparently there is www.techrentals.com.au where you can hire all that engineering geeky stuff like noise meters as well.

Yes, its screwed how you *have* to turn up at the appointed time or else you get fined $1000 - i gotta take a few hours of work just so i can pass and stick everything back on :D I mean its such a pointless system for tuned imports, parts go off, pass test, parts go back on again.

    • If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
    • Lock me in mate, although I'm not sure if I'll be heading up from Goulburn or down from Sydney, either way, return will be back to Goulburn 
    • Sounds good, we will aim to be there! @The Bogan I'll give you a shout if you are heading up to campbelltown for the meet too.
    • Before I get to the test day, just to finish off the android head unit. This is a demo from car start up....the standard/host system takes a few seconds to boot (same as all v37) but Android comes up quickly. In this vid I'm using the delivered launcher but have set the default to Agami since which is easier to navigate when if use primarily 5 apps. You can see the host system still takes over when required eg putting it in reverse, and you can switch between Android and not by holding the back button 3 sec. It is pretty responsive (fast) but you can see I had to press harder than expected a couple of times.  I still have the phone connected to the stock system, and that also seamlessly takes over Android music playing. v37-android-demo.mp4 The bigger reason that I put this in though is so that I can use Ecutek directly on the head unit. That gives me a dash with logging (up to 20MB only), high and low value warnings on any parameter etc etc. I've run a USB cable from the Ecutek OBD dongle to a USB input on the unit, easy. v37-ecutek-demo.mp4   The unit did freeze on the launcher the other day, I think Agami was trying to verify the license when it didn't have a data connection...will monitor and report back if there are any other problems but so far I'm very happy with the upgrade.
    • Nah that is just crappy GPS mapping, I did have a small excursion (cold tyres, damp track, surprise!), will post up that when I get a chance.
