I'm liking this response from Rob. Seems that the ultimate or even blue is what I may need should I decide to upgrade to a larger turbo but stay on the stock injectors and cams.

I have an Ultimate and I love it, I've never used the BLue so I can't tell you the difference, but for my needs the Ultimate is awesome ^_^ although I wish it had some kind of anti-lag or launch control capability.

im very bad at understanding ECUs, but im looking for something that will
1. safely lean out the mixture to provide better economy nd power.
2. delete the AFM
3. allow me to put in my 540s.
is this the best option for me?

To lean a mixture :
with Blue you have to MOD the AFM signal so timing going bad
with Ultimate you could MOD injection directly
overall you could use 540 on both but not with the same tuning method.
With a pressure sensor you could emulate the AFM signal on Ultimate, not sure you could on Blue.
You have to add a manifold temp sensor to make adjustment on inj and ign, could be done on Ultimate, not sure on Blue
I had an EMU, i am now on a standalone (easier for fine tune), EMU is a good piggy as the last MAPECU (they share the rpm vs boost vs AFM output signal to start with), i tried a Blue one on my 205 but i don't like the way you adjust AFR (affect timing) as a SAFC with bigger table so remove it and look after a 2nd EMU or perhaps a standalone (expensive for a DD)

I've had some seat time with an Ultimate, but not a blue. I street tuned a turbo rsx-S with it and I was surprised how well everything worked together.
Here's the reality. If you have a daily driver, you should look at piggybacks instead of standalones. A factory computer has endless hours of tuning for all load/baro/tipin/idle/voltage/etc variants. It would take a GOOD tuner a long time to properly tune a standalone car for street driving applications. People never think of "well how many accessories did i have on during that pull?" or "what was my elevation".. or "a cold front was moving in and it started to sprinkle"... all those things are already accounted for in your stock ecu. Adjusting the Ultimate to level out a/f's is emulating a signal over top of all that base code. Granted, some standalones do help the tuner account for certain variables, but in the end, there is nothing wrong with a properly tuned and thought out piggy back.

Yeh well, i spose i can keep the AFM, i just wanna lean it out atm and use the 540s, ive got a Garrett GT30 now but im not interested in going insane YET. the piggyback will suit my needs atm, i just thought that MAP was way better than AFM because its spose to be more accurate and a lot less restriction.. i know of a tuner locally with a great rep so im not gonna be tuning it until i get some good knowledge.

EMU has launch control capability..

you should go fully tunable ecu or even megasquirt because piggyback does nothing but increases your chances for detonation (which makes it inevitable) because it advances ignition timing....

actually, this is not true with the emanage ultimate.
it controls injector opening time directly, POST ecu.
it can however also do it in the more traditional piggyback style of modifying the airflow signal if desired.
it can also do FCD,2 step, rev delimiter, speed delimiter, and some neat tricks can be done with it like boost control ect.
imo its a pretty powerful little unit, especially if you can find a good deal on one used, you can find them pretty consistantly for a good price on the various boards.
