im in nsw dude ring the rta help line - they will give u the number for the emissions testing centre in penrith as for closed loop - you will find most GOOD aftermarket ecu's these days have a capability for closed loop with use of a 02 sensor - ie. microtech, haltech, etc even megasquirt have closed loop capabilities as for engineering - the way the computer is "locked" as someone quoted rather loosely, is by removing the handset - as long as the fuel and ignition values are predetermined without a handset showing\ available to driver\passenger to alter values the purpose of having this as a prerequisite to passing an aftermaket computer is so that ppl cannot amend any values once an engineer has passed a car based on emissions testing for a given setting - obviously if they are altered (ie more fuel or richer mixtures or timing etc) then the emissions values will change and if taken to an EPA or emissions testing centre for defect purposes, then the engineer's name is at risk for passing a car with shitty emissions the other reason is that if a car has been provided with a standard ECU that CAN be remapped somehow, then no other computer can be engineered unless the car is engineered as an ICV (individually constructed vehicle - READ: BIG BIG money) - this also comes down to emissions and safety so basically, if ur putting a 3sge in for instance, then you need to run the 3sge computer (from australian spec celica or mr2) to control the motor, but if ur turboing say a 4afe which never came out released with forced induction in australia, then you MAY be permitted to use an aftermarket ecu - i stress MAY. Same goes for motors not released in australia either - for eg. the 2jzgte or 4agze maybe how do i know this - im going through the hassles now of engineering my 2.8 litre turbo gemini [Report message to a moderator]
