What ECU to use on a 3TGETU?

[Ta22boy]

Hey all,
im in the market for an programmbale computer for a 3TGTEU and due to not knowing much on this topic i was kinda hoping you guys might be able to steer me in the right direction. Only ECU i refuse to use is a wolf 3D as i have had bad experiences on a mates engine, when his sensors went haywire and then had to spend another 1000 on just the wolf sensors as we were told you had to run them....unless someone can say otherwise..

Cheers

unless you can wire the ECU in and tune it yourself, your limited to what dyno operators in townsville are 'used to' .

most of them wont bother learning to tune other ECUs.


adaptronic is a good ecu that springs to mind. relatively new product so most places wont have heard of them.

Mate I would probably base my first choice on who you want to tune it and what they are familiar with then just go from there...Im running a microtech LT8 and it seems to be ok(not that I know much about it) I paid 300 for it and it was already mapped for a 3tgte.When I have needed to speak to microtech I have and the service has been teriffic .

So first find who will tune it,then ring up the suppliers of that brand or brands (if the tuner has multiple preferences).See what they have for the engine,the cost of having it mapped to suit then keep an eye out for a second hand one.

I HAVE AN EMS it seems great would be worth looking into.

Yeah thats what i have been thinking, not to much to choose from up here, but townsville mechanical services are a dealer for Autronic and seem to be the best i have found so far....
But then again im just trying to find a tried and tested ECU that has been used on the 3TGTE's

How much did you pay for your EMS TIMTAMS as i have heard good things about them as well? much screwing around to get it in there?

As mentioned above you are going to be limited to what the tuners can tune as your in a remote area. Maybe worth inquiring to the mechanical place if they can tune a Microtech. Cheaper than an autronic and well capable of running a tough 3t.

I'm interested in this too and know little.

TimTam, what model are you running?

I was recommended a number of years ago a Wolf 3D. They've gone to 4D now. I was suprised to hear they only worked with their own sensors. The ECU isn't cheap either ($1800+ ???).

Some ECU's apparently have self learning - drive and learn - functions in them (Autronic?)

RiceburnaGTV, it's interesting to hear that the MicroTech has a 3T-GTE base map. The fuel injector drivers are peak and hold type - do you know anything about saturated injectors - what're they?

From what little I've read ECUs that self learn and off the shelf base maps provide a convenient starting point. But I'd like to know how well the self learning works and how good the base maps are. Learning the parameters of your engine and reading the logs of your ECU allows you to improve on the base maps - Riceburner what did you tweek?. While Dyno tuning might allow you to get improved peak power and smooth torque banding etc some recent reading suggests that a dyno tune doesn't represent all aspects of real world driving. For a start the ambient temperatures change in the real world. Is this correct?

My needs are that I would like to load up anywhere between 3 or 4 different tuning maps for different fuels (switching between at least 2 on the fly) and the ECU must handle knock control well; control should allow variable spark advance and also make this dependent on inlet air temperature (or is this basic?), have full lambda closed loop control, measure exhaust gas temperature and allow this to control other parameters.

I read a review of an APEXI FC? unit. A major drawback for me is the PC software is only available in Japanese :-( I've always wanted to learn Japanese though but for alterior motives - something to do with white socks Apart from lack of ability to control certain parameters it did recieve an overall good review and it was relatively cheap. The finish guy posting on this forum running the Beams 3S got one a little while ago - it would be interesting to hear from him too.

I had a look at the Megasquirt stuff the other day - quite interesting - they've got a few things comming out mid year that makes their stuff more usable. Kind of like the idea of a completely open source build your own approach - means that you've got to learn the fundamentals about EFI yourself.

This is all new stuff to me - quite exciting and interesting really

In my opinion i would steer clear of the Wolf. I have seen a car on a dyno getting tuned with a Wolf 3D and it would just spontaneously shut down and reboot itself in the middle of a 8000rpm, 15psi pull. Not good at all. We then ripped it out, sent it back, only to have a new one sent down and it continued to do the same thing. The owner eventually just threw it out and i believe and put a Microtech on it.

This may of been an isolated incident but it definitely leaves you doubting the quality.

I run a Motec and couldn't be happier - but they aren't cheap....

If it happened twice, with 2 different ECU's would suggest that it may have been in the wiring? OR It may well have been thermal shut down of the injector drivers from using injectors with too low impedance? This is covered in the instructions.

Wolf 3D, Ver 3 and Ver 4 and the V500 are quite capable units, you can take them apart without voiding factory warranty (AFAIK the ony management to do so). They appear to be well made. Mine has run faultlessly over 5 years.

Now onto the topic, the best ECU to use is the one that does the job. Any of the well known aftermarket items will do it well enough. Much like a calculator being able to give the correct answer (quoted from James at Groove Ryder). Ultimately the price differences come down to what options are offered.

So, like you have quite rightly decided, base it on what your tuner is comfortable with, as this will be the quickest for them to install and tune - saving you $$$ on that end of the deal.

Either way not enough evidence IMO to publicly slag them.

This was not a public slag - i was simply sharing MY experiences with a product. I am sure there are alot of good experiences also (such as yourself). This is what a forum is for - sharing experiences - and that was mine.

Your right, it could of been the wiring, and this was the first and obvious place to look. this was thoroughly tested and no problems were found, so the unit was sent back, they admitted there was something wrong and sent a replacement, which showed similar issues.

The entire unit was installed by an exceptionally capable tuner, and wired by an auto electrician. The same 2 guys that did my car (and hundreds of others) and which i have never had a problem.

Sorry if you took this as a "public slag", but if you were asking for opinions on a product, and somebody has used that product and had something to share, wouldn't you like to know so you can make up your own mind?

Go for an Adaptronic.
A heap better than a Microtech, and costs less.

Sorry - I was too quick to press the go button whilst working. You are indeed correct, and obviously the car was in capable hands. My experiences have been good with the Wolf.

All good mate - ain't forums grand!
