ECU decissions

I'm a Haltech fan to be honest. Most tuners can refer you to someone mobile that can simply wire in the unit prior to tuning, so I honestly doubt it'll be an issue.
 
Do Streamline have experience with 3SGTE's? They may be good with other cars, but experience has taught me to only entrust those with experience with that motor & have proven results.

If you can get Hitman from Haltech, he's the best IMO. His closest match & many would vouch for them is JEM. Next would Autotech Engineering in Granville & SAS in Silverwater.
 
JEM & Matt have both tuned some of the best 3SGTE's in Australia.
 
If Adaptronic, MRC would be my pick. But as I said, I'd prefer the Haltech.

As far as wiring in to your car goes for the Haltech, can't you get a patch loom? Basically a loom that plugs into the factory harness then the other side plugs into the ECU? Places like Wolf used to offer these a while back but I also thought Haltech do too.
I think Haltech have calibration tables for sensors also so you don't need to change any of the factory sensors.
Depends on what features your really after from an ECU, do you need anitlag and stuff or just after fuel and ignition maps. If its just fuel and ignition then wouldn't something like a Power FC be cheap and good enough?

How much is the Link plug Deco? Looks like you can get a G4 or G4+

Not sure. Im just about to shoot an email off to them in hope to get a quote. Yeah not sure; from what I can tell the G4+ ECUs all need to be wired in where as the plug in is only offered as a G4  Scratch that. I just found a link to the G4+ plug in ECUs

Tuners are usually biased to an ecu. I still know of some that "swear" by ems & microtech.

I dont disagree!
So basically go with whichever one your tuner is most comfortable with.
 
I must agree with MR2QIK; with such a marginal increase on a stock 3S using E85, do you really need that option? The PFC might be the best option in that case especially with how cheap they are compared to other options. 

Thanks for all of the suggestions guys
 
I have had limited dealings with tuners as the only tuner I have dealt with was C&V Performance who tuned our STi when we use to live in Sydney and the reason we went with them was because the guys from Hi Tech Mufflers recommended them, so as far as picking a tuner for my MR2 I will be taking peoples recommendations on board as quite a few of you seem to have some good recommendations from personal experience.
 
As far as what options I want from an ECU, basically I just want an ECU that is going to give me good reliability, drive ability and has good tuner support as my car is a daily driver so I don't want something that is going to be annoying to live with on a daily basis. I like the idea of E85 but I also need the ability to be able to still run 98 due to E85 not being readily available in some areas I travel to hence why I was attracted to a flex fuel set up.
 
As my engine is stock I am looking for the best areas to start improving performance whilst looking after the engine as I am not ready to do a complete engine build as yet so I was thinking the basics for now. Improve the exhaust, fuel system, install a good ecu to allow the engine to be properly tuned and then look at improving the turbo and look at installing a w2a cooling system.
 
I am trying to research as much as I can first before dive in.

I have well over 300rwkw & still run a power fc.....lol e85 is good but years after it was announced, there's still only one within reach for me. Therefore, can't be arsed.

Skip ecu for now & start with exhaust/dump, ebc & a good IC setup. That'll damage your wallet upfront.
