What attracts you?
Whats important to you?
What do you want to aviod and stay away from?

price attracts me

features i like are:

high or no rev limit
launch control
anti-lag ( even though i dont use it)
external high power coils
small incremental tuning points
pc or laptop tuning, no handheld crap
lots of memory for data logging
no software glitches
simple harness ( no such thing )
many many external relays for things like nitrous

thats all i can think of now


i want to stay away from systems that dont care about the customers and systems that have many problems. i.e. link

all of the adjustibility of the tec 3 is really nice

I just wish it was a little more easy to install then i would put my own in...

I'm with Stealth-wrx's choices but would like to add that a "fall back" mode is nice. You know, so when I dork up my settings and the car runs worse that an 82 escort, I can just revert back to stock or a setting that worked

/\rcanum

Having an ECU with no software glitches is impossible. Even the stock ECU has software glitches. The only difference is that they are just not as apparent.

Having a Tec3 the problems I see are.

-Ease to revert back to stock ECU.
(Need to revert back to stock to pass Wa State emissions test)

-Easy to read Laptop GUI.

-Glitch free software.

-Ease of software use.

-Fast Technical Support.

-Ease of replacement sensors or ability to use stock sensors. Tec should be able to accept stock knock and other sensors. (less the trigger sensor which is far superior) Maybe with a firmware pack.

..all standalones can do a form of anti-lag. Very easy, just program it to retard the timing and dump excess fuel once you hit a vacuum condition. the mix of the 2 will create an ALS system for you. very simple explanation but i've done setups like that before with TEC and SDS and it works great, just burns throught turbos and manifolds like a kid eats candy. :D

AVCS control (LINK wake up)

anyone here ever try the sds system.

yup i have the EM-4F setup right now actually.
couldn't be happier with it for the price.

The new features I am looking for are:

1.) Wide Band O2
2.) multiple Maps to switch between
3.) Anti-lag
4.) Launch Control

Guess I am getting into a slightly different realm of tuning. Looking for the best in a race car but at a decent price. Or I coudl just jump up to a Motec or better

My top two are

1. Plug and play

2. Wide band 02 input capabilites

but I also wouldn't mind...

1. easy to use software and not old DOS apps(Unichip) or terminal emulation crap(UTEC)

2. Good vendor support(thats tough for any company though)

does anyone know what the limit on the factory coils are?

1. many zones which ALL are adjustable
2. wideband O2
3. ability to have more than one map running at the same time!! of course one will be the one that is running and the other will be like a ghost.
4. lastly, the ability to tell the user that he/she is a complete moron and to go and have a professional tune their car before they start ragging/*****ing on how ineffective their tuning module is.

1) Good Technical/Tuning Support

2) Wideband Capability

From what I've heard, Link is soon releasing the wideband feature for the Link Plus :)

an "auto tune" function would be nice, that way I could shoot for stoic at idle or at least a little rich.

does SDS work well on 02 wrx ?

decent resolution (greater than 8x8)
ability to use any sensors (gm, stock, whatever)
integrated wide band
High or low impediance injectors

High or Low impedance is just a resistor for each injector. That is all the Tec and many other units have in it to allow for low impedance injectors.

The resistors by the way cost about $5 total, then just connect them into the line and you are all set. So putting them into a Engine Management unit should be pretty simple. On to use them and off to not use them.

I chose Autronic for my engine management because I hate re-tuning for different weather, and different altitudes when driving.

Check out this link, pay particular attention to the "Fuel correction and timing correction factors". The more factors, the better the ECU adapts to changes, but the trade-off is, it's slightly more complicated.

Hope this helps.

Being able to quickly and easily switch between different maps depending on the weather. For instance one map for the winter time when the air is nice and cold. Then a second map for the hot humid summers.

The price is also a big concern.

Being able to get quick support if something goes wrong with the unit.

a wideband O2 connection

ability to read EGTs also

datalogging lots of it

quick default setting for if I screw up the maps and want to quickly go back to the orignal settings to start over
