I hardly know anything about EMS, but I thought I'd try to organize this EMS bickering into something constructive. I think the only way to properly choose a tuning option is to compare them independently of the car they are installed in.
*EDIT: All of the names are now links to where each can be purchased.*
AEM EMS
Base Price: $1875
Extras Needed: ??
Laptop Compatible: Yes
Tuner: Beau @ MAM
Controllable Functions: Everything
Pros: Offers a complete standalone setup & does it very well
Cons: Very complex & very expensive
Final Word: Doesn't seem necessary unless you're building a Protege race car or you're a "Super Tuner"
Haltech E6x
Base Price: $1400
Extras Needed: ??
Laptop Compatible: Yes
Tuner: Juan @ HiBoost
Controllable Functions: Air/Fuel & Timing

Extras Needed: ??
Laptop Compatible: No
Tuner: Unichip dealers/Corksport
Controllable Functions: Air/Fuel & Timing (manipulated)

Airflow Logistics AFC

Extras Needed: Boost Control (depends on method), FTC (significantly more $$)

I can add more to this as I get more info or if anyone has suggestions.
