Hi guys, just wondering if anyone has thought about this, apparently emissions testing is coming in and from what a friend told me they put a machine on the exhaust with the vehicle sitting there is neutral and one of the tests they do is a sharp throttle stab from idle. (Is this true? dont really follow the news much)
I have recently turbocharged my cruiser, and increased the fueling by winding in the full load screw, and was going to get it set up correctly by a specialist to avoid molten engine parts. Because it has no aneroid or 'boost compensator' it over injects fuel when there is no boost and chugs some soot.
if you are not a retard like most people you understand this and learn to control this firstly by not driving like most housewives drive their prados around getting tyre smoke and then fanging at 80kph wastegating past schools etc.., and secondly by watching exhaust smoke and by feel as it actually accelerates better with part throttle before boost.
When the testing comes in it will definately fail so just wondering if anyone has any cunning plans. without mucking with the full load screw every warrant.
best ive thought of yet is by winding out both the full throttle stop screw (not full load screw) and the screw under the accelerator pedal.
anyone tried this?
emissions testing of turbocharged diesels without aneroids
Few WoF testing places will have the technology at their disposal. All the rest will have to rely on visual evaluation and therefore open to interpretation.
The content of the proposed WoF ruling was (i.e. it may have since changed) that it was to be based on depressing the accel. pedal for 5-10 seconds...not just a blip on the throttle. So even without an aneroid, the exhaust should clean-up within a few seconds.

Not exactly relevant but interesting. I have just seen the new DAF truck turn up at work and it is equipped with the euro 4 spec engine (for those of you who do not know europe are insanely tough on emmission control and the new trucks entering or being built in europe now have to meet the new euro 4 spec) what they have come up with for emission control on top of everything else is a new fuel tank to hold eurea (I think that's how you spell it) and then the eurea is injected into the muffler (a special design muffler, half muffler half catalytic converter) and when the eurea is burnt with the exhaust gases a whole heap of poisoness gases (can't remember their names but you know) are eliminated creating a cleaner exhaust into the atmosphere. I tried to keep it as simple as I could so there you have it. 
wow, urea-thats a product of urine. They used to collect it from the urinals at public schools and make fertiliser with it. awesome! Just a matter of time before trucks and busses start having electrostatic precipitators and SCR units on them like power plants! cool.
Good news about WOF testing. If you take it for a thrash occasionally my cruiser doesnt seem to smoke much at all if you drive normally. Must burn the soot out of the injector nozzles or something.
I think the biggest thing that could improve the emmisions of diesels is driver education - if people actually cared at all they would realise diesels chug smog with foot to the floor, and about 10 times less at 2/3 power.
the latest turbo diesels seem a lot better but even touregs chug smog ive seen it.
Also, does anyone know why japanese manufacturers used to put such ridiculously useless diesels in vehicles!? why is the diesel always smaller than the petrol too? went for a burn (or should say an extinguish) in an old double cab hilux the other day.
why!!! how are you supposed to tow anything with that!? they could have put a v8 diesel in- part load efficiency of diesels is excellet compared to petrols.

thats an adapted cruiser engine-315hp marine rated but my cruiser had 135hp beeoooooo.
toyota could have done that, like the americans do but they decided to spend the time covering all their bolts in seizing potion instead so no-one can work on them.
