Default Engine Management Systems ( EMS )

What are the EMS out there for the WRX or even the STI ( I'm hoping everything that I buy now will "bolt" directly on the STI if I ever decide to go w/ it. Anyways so I here about all these different types of full EMS ... AEM, Link ECU, Tek 2 & 3, etc. It seems that they can all be programed w/ a laptop; do they offer a default setting w/ a push of a button so if in the far future I mess up a tunning day I can restore everything back to default? Can I get someone to tune my REX once and have all the factory settings or does the EMS already come w/ preprogramed settings for each specifc car? Is one really any better than the other performance wise? They seem to run between $1550-2500? Any thought would be nice. Thanks.

In the coming weeks, I will be putting a PEMS turbo kit on my WRX. Buying it from someonelse on I-club here. It's a Vishnu kit, so it shouldn't be that hard to setup. From my understanding, all programming is done from the laptop and you can also datalog with it too. I will post further when I recieve my kit and install it on my car.....

Default Re: Engine Management Systems ( EMS )

Damn boy! You're planning far ahead aren't ya? Hmm...well with ANY EMS, you're gonna have to find someone to tune it for you/do the programming or you're gonna have to learn yourself, but I've heard it takes years of experience to tune EMS to take advantage of its full potential. One simple mistake can lead to disaster and/or a car that's undriveable. Why are you thinking about going with a stand alone? Don't forget about motec. I dunno if any come "pre-programmed," or if they can keep factory settings. I'm sure a stand alone will give you the best performance if you can get it tuned right (ie: by someone like Shiv), otherwise, you'd probably end up with little or no gains (or maybe even worse) over something like a unichip.

I try to plan ahead, hey you never know when a good deal may fly by . I'm just trying to figure out the whole CHIP and EMS issue ... my big issue is ... "Well if I'm gonna spend $700+ on a UniChip and then have to ship it back everytime I do something, then why don't I just get a EMS for $1500+ and do the programming myself w/ specifications from people who have already tuned a WRX?" Of course this is all in the far, far future.

I also bought the link Engine management. and had to send it back. They first said it was to agressively tuned for the US do to lower octane gas or something.I well get mine back some time this next week and I will repost with the new results.

I heard the Tec series were the best, is that true or is it just promotions? Are they PNP? I'd rather look into PNP EMS. Have you guys/gals had any problems w/ the Link ECU? Can't you tune everything yourself w/ a laptop?

I was told the US Link ECU had to be developed and very few were on the market with more coming soon. Supposedly the recall isn't for something as simple as too "aggresive tuning" for US's lower octane numbers (think about it; that is part of the settings in the software, not the ECU itself), but rather the ECU had trouble at high rpms with electromagnetic interference from itself and would shut off. If you look at your freshly recalled ECU, you will probably find a shield between some components.

So is the Link ECU fixed now? Is it dependable?

The last I heard (before I cancelled my order) is that about 10 are in the US (actual PNP US Links) and the next big flood of them was delayed due to the high rpm interference thing. I would expect they have them fixed after that, but I don't know if they even got back out on the market much yet.

Just get the AEM system, it's supposed to be PNP. Then let us all know how it worked out...

I wish I had $XK to throw around on a EMS! Humm I swear I wouldn't mod my car to go faster. Anybody know how much the AEM EMS will be? Do all EMS have default settings for each car? Can we tune it ourselves or is it something I shouldn't even look into?

It depends on the ECU.

The AEM will be around $1800 according to...AEM. That's MSRP. You're practically in Tec2/Pectel/Motec territory then.

I think the AEM EMS is 1600 for the WRX. It should have the default map already loaded for the WRX since when you order it you have to specify it's for a WRX. It's tuneable with a laptop but you won't get the best results without a Dyno. You also have to be careful since with this amount of control you can make your engine do things it shouldn't and blow it up or cause it to sieze.

i just talk to my tuner and he said i should have my new redeveloped link ecu hopefully by the end of the week the problem was just as thw wiz said the computer was interferring with it self when under high boost and rpms and would shut down. lets hope this will fix it because for anyone who has a links youknow what it is like to wait and wait i just want to get my car finally tuned it was running fine with an avc-r and afc but i was convinced into purchasing the links and sold my other components lets hope i made the right decision and all of the problems are fixed.

Hrmm, I ordered a Link from Sandstallion about a week ago. He said it was "in stock" and it shold be here this week sometime.

I hope it doesn't mean it is a "pre-recall" unit.

Guess I'll find out. Anybody know what to look for to see if it's fixed or one of the faulty ones?
