Default Best ECU for complete engine swap

When swapping a complete engine and not retaining much of any of the stock characteristics... What are the better ECU's??? Anyone actually done a complete swap without installing that engines ECU first?

I'm considering Tec II/III & Haltech E6K... any others?

I've got a complete EJ22T engine that I will be throughing into my 1997 OBS. I have the stock Legacy Turbo ECU, but only want to use the wiring... not the ECU.

The engine will not be kept stock so it would be no use anyway.

Thanks - Jon

Well, there is always the other common standalone around here. Link Plus. It'll run it.

I would vote for TecIII and STAY AWAY from Link(anything)... or you could try the UTEC... oh wait nevermind .

You probably already know about it but might want to check out www.wrxhackers.com. It's a discussion forum for just WRX ECU's.

You could pay twice as much for a Tec III and probably not be able to tune it yourself from the start or even able to get it started at all.

Or you could get something else that could get you up and running much faster, and at half the price. My vote Link Plus.

Though it all comes down to what you want to use the car for? Track use only? Daily driver? What kind of tuning are you looking for.

Hisssssss, hisssss...

Talk about opening a jar of worms.

EVERYTHING has their downsides... what you want to do is what will suit your needs.

You can do it with a TEC, but do you really want to adjust fuel by Volumetric Effeciency settings?

You can do it with a Link, but do you really want to deal with their whacked scales of adjustment?

You can do it with a Haltech, but do you really want to deal with wiring it in yourself or doing your own troubleshooting since the user-based is fairly small?

You can do it with a MoTeC, but do you want to spend that much + see Haltech.

You can do it with an Autronic, see MoTeC.

You can do it with any other standalone, see Haltech.

Personally, I like the Haltech's real-world settings, the Link's PnP-ability, and the TEC's user-base. I like features that the MoTeC has that others don't... well, I'm sure you get the point.

Your reasons for this conclusion?

I'm swaying to Haltech the more I talk with Nick... the only thing hindering it is the lack of support in the subaru/i-club market. If more and more people gave it a shot and we got more support I think it would be much better than electromotive (what TEC derives from) and is still less money.. No subaru specific kit, but those are overrated anyway

i really wonder if the link nay sayers are people that have delt with the plug in link or the link plus

the reason that i am leaning towards the link plus is the pre-fab harness that are avaiable from the sand rail guys... oh yeah and the base maps for the EJ20G...

haltec e6k is about the same cost 1045+3 bar map sensor + ignitor but no knock control and no base map

the e11 might be the ticket .. if it ever comes out

right now i may use my 1.8 ecu and try and use a e-manage (cheeep!)

in discussion the people have steered me away from the tec2 .. aparently pretty buggy and the tec 3 is just toooo expensive 2400...

For the record, I got a 2bar sensor from the junkyard for $10, and you can use the stock ignitors. Pish posh, who needs a base map?

Still, no knock control. But I'm getting a J&S personally, just because I want to make ultra-sure that this one doesn't blow due to detonation.

You forgot the Simple Digital Systems EM-4 in that list of standalone EFI systems.

I used one of the early EM-1 systems on an EFI conversion ported 13B rotary in a 1st gen RX7 a few years ago and it turned out pretty darned quick. I liked it because I could use a pilot's leg board and velcro to attach the programmer to my leg to tune on the fly instead of needing a laptop.

Just another option.

I do as I won't be running the Legacy ECU to get a base map data log... oh and don't know if I can get this from anyone else as they are OBD I.

Jaxx,
Can you give me some direcion/link to this sandrail place that offers harnesses and what not for these engines??? I know the harness won't work with my engine either, but the base maps might give me a start and the Link Plus doesn't sound all that bad, as long as it isn't like the Link piggy back.
