Can aftermarket ECU's be complied/engineered

[RONA]

i have spoken to an engineer who told me that i have to have an OE computer too pass , but then again he may be just saying that so it will pass without a problem but he definently said any ecu that can be reprogrammed is illegal

So standard Nissan and holden ecu's are illegal then

i guess if thats what the enginner said then i suppose so !

stait from the horses mouth , i'll keep my pie hole open thanks mate

It's times like this we need a spellchecker. Read the thread again, what you said was wrong.

Not to mention if you look at most toyotas, the stock ecu tunes are as rich as so the aftermarket computer are a gonna to be better for emissions and b more fuel efficient.

since when did the rta start doing things logically

since when did the rta start doing things logically?

they haven't but thats the point, the whole system is F***kin stupid, would be fun to contest it and just blatantly lay out the facts in court, but I don't think anyone has the time or money to bother.

whoever neg repped me , when you check with an engineer on the rta list you can put the rep point back up one

thank you to whoever that was

the rule is, as cruz states above, that the computer MUST meet the ADR's of the engine it is controlling. and it MUST not be able to be altered later. aiui, the MoTec was the only one that could be truly locked out, and as such was acceptable, WHEN it had been tested to the emissions standard of the ADR that is required for your engine/car (this applies to older engines in newer cars also...). a plug over a port may not be enough to guarantee it cannot be change. removal of the interface to a tuning device would be.

to be absolutely legal, it has to "meet the ADR emissions of the car/engine (whichever is newer) and not be able to be chaged later"

in the case of PRB and CSV, i think you'll find they they HAVE gone through this testing procedure, and they have a tune that they can preprogram into the Motec (which then has no capacity for reprogramming) and then when fitted to STANDARD engines (or the setup used for the tests), the engines WILL pass emissions.

the actual rules are pretty simple. must pass ADR emissions. cannot be altered. n way around that..... except to fit AM ECU into OEM case AND tune it to pass emissions

and yes, this may just be my opinion, but based on the RTA rules as i read them from the code of practice, as i read the ADR'S and as i read the proposed regs.

and as stated. it is particularly important to remember that engineered does NOT automatically mean legal....
in NSW, you no longer have to go over "the pits" for an engineered vehicle and it is left up to the engineer to ensure compliance. lack of compliance can be proved at a later date after an accident.

[oldcorollas]

as for the nissan holden thing...
aftermarket "chips" are also not legla unless complied for that particular engine combination.
older and now newer holden ECU's are easily reprogrammed thanks to the cheaparsed design they used. however, holdens have never been illegal because of cheap-arsed designs
IF it could be shown that an owner had tampered with the ECU, AND it no longeer met emissions, then they could be fined.... but it's not very easy to do, and not very likely...
however, if a twin turbo holden V8 VT or something was pulled over by the EPA, and it was still running the stock ECU.... they are not that stupid.

[RONA]

I wasn't referring to chips, though, and yes obviously a twin turbo LS1 running a stock ecu, but one running say bolt ons, maybe a cam, head and new manifold package (looks the same as stock but outflows it massively) and LS1 edit is good for plenty of power talking near 350-400kw at the flywheel.

so what? unless it has tested emissions... it's still not legal... tampering with any emissions parts on a car is subject to a fine
if the EPA pull over said car, test it, find it to be over, then send it for further testing.....

what is your point exactly?

Just a quick question, tried to search but found alot of contradicting info on this subject.
Basically would just like to know if it is possible to get an aftermarket ECU engineered or complied in SA,aslong as it meets relevant emissions standards?
Car in question is my 1JZ MX73 on standards turbos, injectors and ecu.

NOT in SA ,every thing from pods & dash mounted guages on up to a jet engine is a Defect for any car made after mid '80's and most made before. Sorry dont know of anyone with a Locked ECU & eng. certificate being roadworthy here .

[CrUZida]

To anyone who says Aftermarket ECU's are not legal

The above is from the National Code Of Practice.

An AUSTRALIA WIDE document written by DOTARS that is in use right now.

What it says goes. Fullstop.

[ToDa30/4]

maybe so, My GT4 was declared un roadworthy because or a/m ECU plus other nice things like 264o cams, injectors & so on, regency would not accept any eng. submittion regarding emissions because ECU is programable. unit in question is a Link Plus ECU
