Default link ecu or tec 3. what do you think

link

pros:

plugs right in
cheap

cons:

people say it has many glitches and problems
some are having fuel pump problems with it
not all tuners are familiar with link


tec 3

pros:

very accurate device
electromotive is familiar with every tuner
shiv makes a bolt on kit for subaru ( easier for me to install)

cons:

twice as much as link
more wiring
i have to change all of the sensors out on my motor



here is my configuration so far:

2.2 legacy fully built block with 2.5 crank ( 2.35 liters)
ported and polished wrx heads ( i am not changing the cams)
custom equall length turbo manifold
t-66 turbo
blitz front mount

should i get link or tec 3?

any advice

Have you considered an AEM computer? I can make you a harness to make it plug and play and it's very flexible in it's abilities. Only bad thing is no base map but I can provide that for you as well if you want.

Thanks

The ultimate PRO for the TEC3 - 60-2 tooth crank trigger wheel, giving 1/4 degree spark accuracy. Effectively ZERO spark scatter - you can actually tune your awesome motor to the limit (or wherever you choose to tune it to), and know that it'll run at the limit... not a little bit beyond, or a little bit shy of the limit.

Oh, and you don't have to change all the sensors. You have to add the crank magnetic pickup sensor (bracket supplied by vishnu), crank trigger wheel (supplied mounted to an oem crank pulley by vishnu), coolant temp sensor (sensor mount provided by vishnu - you must cut one stock coolant hose and hose clamp the sensor mount w/sensor into the system - about 5 minutes), air intake temp sensor (you have to drill and tap a location of your choice in 3/8 NPT - about 10 minutes), MAP sensor (as simple as running a vacuum hose from the manifold), and a knock sensor (with an adapter supplied by vishnu - about 5 minutes).

No doubt TEC3 for your high level of modifications. Like Austin said, you will benefit greatly from the coil pack that the TEC provides at your power level. The link is great for most people's needs, but in YOUR case, I would say to spend the extra cash and get the TEC.

What actually costs more?? Spending the extra cash now for a better system or spending the cash later to fix your motor cuz you tried to save a few bucks in the beginning.

I don't dislike the Link, its just that for highly modified motors, I like the abilities of the TEC better.

I think a lot has to do with what you are plannign to do with the car. For lots of track use where you want to win, the Tec 3 will be better as you will be able to dial in every last bit you need to win. But if you are not looking for that, but something reliable then the Link will work very well.

In the end it is up to you and what you want.

TEC3 would be the way to go (yes, we are biased .

LINK is a nice solution for someone in the bolt on level, but you are way beyond that point given your setup.

the AEM is a nice enough unit, but won't imporve the stock ignition system at all, which again, given your setup, you will want to pay close attention to.

Who are you planning on having tune it? That should be your #1 factor in deciding which ecu to use....use what the locals use

Default what about GEMS

What about a GEMS ???? We have tuned with it before as that is what we use on our OOPNE class STI RA ver4 rally car. Able to control electric center diffs, everthing. Plugs into stock board as well,m similar to a link. Other optino that is used in the industry is MOTEC, very expensive, but very, very good.

Call us for more info.

Autotronic . Same plug-in-play like the Link. About the same price. The auto-tune feature is alot better than the Link. Has anti-lag , launch control , etc.

Just clarifying, Link also has anti-lag, launch control, shift light, if you like that sort of thing, etc...

I love the auto-tune feature of the Link is pretty good if you know how to use it, though the problem is not many people do.

I think its LinkPlus that has anti-lag and launch control. Link itself doesn't have those features..

Ah very good point Daniel son... Link Plus, but also some WRXLink's do also have these features, of course you have to pay a little more.

The autotune feature on the TEC3 is super simple. Two clicks, they you tell the TEC how many data points it needs (more data points = more accurate, but takes longer). The TEC will change your VE table (fuel map) to give you your desire A/F ratio (programmed on a 16x16 map). With programmable EGO feedback and response, and even programmable O2 sensor characteristics, you can do everything.

No anti-lag, though...
