What about this

The gains would be pointless because the car is mivec which is VVT. So i dont see how you could safely change the timing because of the variable valve timing that the car already has. If it does work the gains would be very minimal, maybe 2-3kw. I've been quoted for an adaptronic standalone ecu. My local performance shop reckons they are very good and would get some good power out of the car.
 
you could also try the Haltech interceptor these do work quite well. there have been significant gains - the tuning shop I go to he believe that with my current setup if I change the tuning on the car I should see close to 165 atw... you have to be careful of what you buy from RRM as there cars are different again in there programming

Urran - we also have twp cats and other emmission stuf we are also not allowed to modify our cars but we stick our middle finger high in the air and say catch me if you can... we are all prepared to wear the consequenses if we get caught.
 
chowetime sounds familiar :D But we have to go to MOT every year (where as specialized engineer checks basically the whole car) so the term "catch me if you can" really doesn't fit :D Police cars have automatic plate identification software (if you drive past them) which tells the police, if you haven't done your yearly MOT in the given time -> ticket! :D

But still to the topic: Can you give me some detailed information about the tests where you have tried to access Mitsu ECU? I can, if you like, give a detailed DIY instructions with photos.
 
Nothing more than: "Told you so" :D

But the ECU really doen't have to be taken off. The tuning and reflashing is made with the OpenPort cable as seen in the picture, through a flash connector near driver's pedals. Even as it is odd to me, 4G69 seems to use OpenPort 2.0, rather than the newer protocol, 1.3U.
 
I dont believe Christine was saying there was any issues obtaining the ROM, rather somewhere between the process of developing a def file and flashing a modded ROM back onto the ECU was causing issues with the ECU's immobilizer. Whilst I have little knowledge of the overall issues perhaps there is some sort of checksum or form of watermark that the immobilizer is checking in the ROM. I believe the reason we have the immobilizer is due to the ADR requirements for one, pretty sure they were made mandatory and presumably had to meet the rolling code requirement.

Also keep in mind if you swap out an AUDM ECU for a USDM one and your car is stolen and retrieved with damage insurance will not come to the party if they find out...

As for all that stuff about emissions, Australia tends to follow the Euro standards. The strictest standards for emissions are actually California in the US I believe. I know for the CJ Lancer they got a different model that had 3 O2 sensors and 2 cats (as opposed to 2 O2 sensors and 1 cat elsewhere in the world)...
 
Looks promising, I'd be keen to be a guinea pig for some I this stuff if I could find a bit more info.
 
hmm well what i linked did imply that the reflash they were performing was on the Australian delivered ecu, not just a reading. This being said, I'm not trying to say it's possible or impossible, just that I'm not completely sold on it being impossible if that makes sense.
I'm contemplating having a go, there's a lot of documentation on the website, technical guides, and guides in general of how to manipulate the different variables.
I do see what is meant though by messing with the immobilizer and the issue's that presents...
 
Like I said earlier, we have the Immobilizer too and it is not a problem. It is possible, that you cant' just put someone's rom to your ECU. I use my stock ROM that I have taken from my ECU, modified it and put it back. It didn't even come to my mind that someone would want to use some "premade" rom. Every engine, even from the same day and the same assembly line is different. Same rom would work differently on different motors.

Definitions are not something that are just for one rom. They are for one type of ECU. So If someone already has made def's to your ECU then just download them, put them to your ECUFlash Rommetdata -folder and open up your own rom. It will use the definitions to your rom.

I am not so expert on making definitions (yet at least) but there is people who make definitions for free or for very little money. And like I said before, I believe def's for 4G69 are already made.

My friend (more into tuning multiple car's, I just do mine) told me that if you are uncertain about the possibility to reflash your ecu. Take the ECU off, open it and take a picture of it and he'll take a look what chipset it is running. He was 100% confirmed that it is easily done.

BTW We do have two cats, and two O² sensors. But you really can't just talk about EU regulations. Unlike the states, we are not one country and we have huge difference in laws (I know, different states have different laws..). There are many models that you can't bring to Finland, that you can to some other EU country.
 
I contacted RPW and they told me they are capable of reflashing factory ecu's in their workshop. I asked about if they had trouble with the rolling code immobilizer and they said they had no issue.

ahh well there you go, thanks for doing the homework, now to figure out if anyone can do that in victoria
 
rpws workshop is literally 1 minute away from me. but im not trusting em tbh. heard a lot of bad things.
 
I've heard mixed stuff about RPW so who knows, at least it's not like LLT where you mostly hear crap and rarely a good news story! Yet people still seem to deal with him...

Irving (ofey) has the cable to read and flash a ROM but you would need to have the definition file for your ECU if you want to start editing parameters in the ROM. You'll also need to find a tuner if you want to start playing with the AFRs....
 
It's a start, and we all need to start some where
It might be a good idea to talk to RTR, ill ask the guys at techsports when im down there
