What ECU to use on a 3TGETU?

[GasedT18]

Come on guys this discussion isn't surely just a matter of I'd go X or I went X because they're good and cheap or expensive and they worked for me and I could find a tuner to tune it or not - this is hardly an illuminating technical discussion. Bill surely you can do better.

Even discussion about feature sets, programming accessability, PC software quality would be worthwhile. It seems people get one get it tuned by someone, chuck the handset in the boot and never think about it again - yeh got one of those - points to sticker on car - they're good but expensive

Hearing that two successive Wolf units failed for one person is noteworthy. If Wolf accepted responsibility that's good business ethics - but did they say what was going wrong - I presume they would have looked at the fault logs and figured it out. After market support certainly is a factor to consider as is the ability of the units to run a wide range of other peoples sensors.

No, I meant it.
I was merely frugal with words.
If you want me to waffle on with all sort of guff ....

No Bill,

an informed technical review of the pro's and cons of the systems you've used and your experiences as to what lead you to the choice you made. It's up to you how much effort you want to go to. Remember the topic began about the choice of an ECU for the twin spark turbo 3T-GTE - presumably running on PULP. Myself - propane, then LPG and perhaps occasionally a high octane petrol. One day if the industry can get their act together and me get my act together with the $$$$s - sequential injected liquid propane/LPG.

I run a wolf on my engine (1JZ) and i havent had any problems with it once it was all running properly. Because the 1JZ's use Reluctor crank angle sensors, it made it a bit difficult to use, because the wolf usually recognises Holographic Crank Angle Sensors (Found on RB/CA/SR engines) apart from the whole sensor setup bullshit that i had to endure for 2 weeks before we got it running properly, it has run flawlessly. Hand controller shows some nice information, and includes datalogging. Helps a fair bit. I would definatly reccommend a Wolf, but thats just me.

EMS i paid little for but i did have it installed over 11years ago so it wouldnt be fair to say how much, and it was also the first twin coil pack setup they had done.

In short, 11 years is along time to improve and i was really impressed back then. Come to think of it im not sure that the ecu im using now is even up to date?

Hey guys,
Thanks for your all your input, but to be honest im starting to lean to microtech as i know a dealer up here, and plus as gassedT18 says they have a base map for a 3T-GTE where as adaptronic is a bit of a unknown quantity, and would probabley need a capable tuner to even to get it too run right.
Also i have been reading a lot about ECU's in a book called 21st century performance and basiclly they say if you dont have the base map, you are normally taking your car back to them each time the weather changes to update it for different conditions (temp,load,etc) but i think i will still check out adaptronic and maybe wolf, and go from there....

Thanks again guys
Scott

Base map = able to plug and drive straight away...sorta

Think of a base map as the bottom of a flower garden - its only the start of your garden and you need to add flowers - or in this case add the rest of the map. Not having a base map doesnt mean youll have to get it tuned all the time, it just means that between installation and tuning the car wont fire or do anything. A base map will allow you to start the car although it will run rough, and drive it maybe in and out of your workshop. However, these base maps are only tuned for say 2000-2500 rpm max afaik.

A base map also means less tuning work as stuff like sensors and things about the engine are already known to the computer. Without a base map you need to tell it what your using. ie what type and size injectors, coils, o2 sensors, and so on.

Hope that clears it up.

hey besides the common big brand ones you can also use a delco as some people have done on a 3tgteu, i have one adapted to a 3tgteu engine at the moment. its cheap to buy the setup but expensive to work on from what i have heard.

else adapatronic seems really good and fairly inexpensive, go the megasquirt if you have a lot of days off to learn about efi or want to tweak it yourself

i think one big advantage of using a name brand one is the support from the company and that more tuners would be able to work on it,
but the initial cost may be quite high. maybe an second hand name brand older unit would be cheaper to purchase and then reprogram to suit 3tgteu?
