AEM EMS Version 2: Install & Tune at STM
This is one of the first few Evo's to have AEM V2 installed.
Here's some quick specs on the car:
2004 SSL
Stock FMIC/lower pipe
23 psi falling off to 20 psi
STM Intake
STM Upper Intercooler Pipes
3" Turbo Back Exhaust
Stock 2005 turbo
Kelford 272's
AEM EMS Version 2
Stock injectors
Stock intake and exhaust manifolds
What Emery has to say about it:
Just like Everyone else, I like it. While we were tuning it I decided to do another test as we were already there. The whole time Tuning the car we left the stock maf/filter setup installed. The last pull we removed the factory maf and started another test, Watching the wideband go leaner right away I knew we were looking at more power. IT picked up 5 whp all the way through and about 10 at 7k. Thats quite a bit with no tuning and running such low boost. That alone tells me SD is worth it. With more power/boost there would see a bit bigger difference. I know David did this test already and found even more power then we did, Im sure it was on a higher power car though.
As far as the system goes, It seems to work very well and once I got used to it, it was very easy to navigate. I'm sure there are still some bugs here and there but I think over time they will get worked out.

I've got a video uploading now also and will post it up shortly.

The main reason for the jump is to learn the new software. Other then that, Its just better IMHO. I know everyone has their preference and Mine is simply not the stock ECU. Does it work? sure it does.
Truth is I hate computers and am not very good with them so when I want it to do something and it doesn't I get frustrated beyond imagination. When you enter a number in any given field in the AEM software, Thats what it does! Its simple and consistent.
Another reason for the switch is for testing parts. With AEM the car does not calculate between load cells depending on 50 different variables, only boost X RPM. This will help to ensure the same timing/fuel map time after time making tests more legitimate.

YOU TUBE VIDEO!
I used a new camera, and I don't have any software that will edit these (in a reasonable time) so you're stuck with just a single pull, but you also get a walk-around of the engine bay and a look at the dyno graph
...And a GREAT look at our new STM Upper Intercooler pipe kit!

Depends on what you consider "overkill"? If I can gain more control with a stand alone, why not use it? The car seems to have made a lot more power on our dyno then any other Evo with similar mods running a stock ECU. Remember, Evo's on our dyno that make this kind of power go mid 11's.

Yes the stock ECU is great, but people should remind themselves, there are many advantages to a standalone. How about a short manual which describes how EVERYTHING works, put simply. For the stock ECU, there is no manual, and you have to read about 5 million 100 page threads and you still don't know the full picture of how the ECU operates. Standalones you get real map tracing and integrated datalogging.
Stock ECU is cheap, has great startup, idle control, knock control, temp&baro compensations, and some other advantages. But much of those points can be achieved with a standalone if the mapper and ECU are very good.
Emery, how does this new AEM's knock control work?
