want to go supercharged.. will the aem f/ic work with an m62 supercharger and larger injectors? thoughts?

 

That is what it is meant to do, so I would think so, but you would be one of the first to try it out.

 

yes, it would work...it what im doing as well

 

the only thing is.. there would be no way for me to pioneer this.. cause i have no clue how to begin to tune.

 

you could take it to a shop to be tuned. The AEM software is pretty widely used so I doubt it would be hard to find someone to do it.

 

and their is a fourm on aem's site that could help you...id venture to say the unit comes with instructions as well

 

does anyone have one of theseon thier car yet? do you guys thunk u could make power over a stock computer, on a na car?

 

shure. Some advanced timing(can't do it with the aem fi/c) and playing around with the a/f ratio could net some gains.

Really the fi/c is meant for boosted apps though. If you're looking to tune for na I'd go with the smt unit.

 

agreed, the f/ic is mainly a FI tuning solution, as the lack of any ignition advance and RPM limiter modification are pretty much necessities in a high power NA motor

 

The SMT-6 would be perfect for NA Tuning. You have a +/- 40 degree control with the SMT-6. I really wish the FIC had the same capabilities but oh well. You can tune closed loop using the narrowband o2 signal.

Yes, i have spoken with AEM about the unit and they have informed me that the original unit made was first tested on the 05-06 cobalt 2.2. The reason they do not have a harness out for us is because that was not the production unit, so the pinout is different. I have actually made a Wiring diagram for it but am not quite finished. If someone asks me to ill finish it and post it in a How To or something. Looks like a lot of people are getting interested, maybe i should finish it heh =P

 

i want to get AEM fic, but im waiting for someone else to get on running, than i can just copy their mods, and hopefully they'll send me their tune file

 

wait, does FIC stand for fuel/ignition controller or fuel injector controller...I thought the FIC and the SMT were the exact same thing.

Also if the SMT has control over timing then why was it such an issue with the boost? I know there is a lot of stuff that SMT unit is supposed to do that nobody ever got right...

 

FI/C is just Fuel injection controller. It allows the use of larger injectors in place of the 5th injector like the SMT units use.

 

ohhhh okay and this entire time I thought it would help with timing...well what are you boosted guys going to do about timing then?

 

Its Fuel/Ignition controller. It will control timing and fuel. The difference between the FIC and the SMT unit is that you can spoof the ECU into thinking you still have the stock injectors in with the FIC. The SMT will only control seperate injectors or alter the o2 signal to make the car add or remove fuel. The SMT have the ability to add and remove timing, the FIC can only remove it(i read somewhere they recommend not pulling anymore then 11-12 degrees). The FIC can also spoof o2 signals. SMT and FIC can do a MAF clamp.

If it were possible, i wish Perfect Power could combine the functionality of the FIC into their SMT unit then you would have the best of both worlds. You would have amazing fuel control and timing control. The SMT is very good for timing, but a little harder to work with on fuel.(Thats if you dont like the secondary injector idea, though its exactly how nitrous works).

Incorrect. Fuel/Ignition controller. it WILL control timing, but not as well as the SMT units.

 

ohhh okay I was going to say, how the hell did I miss all this when I've been reading every single thread

I thought they both had the same functionalities but I get it now...that makes more sense to go with the AEM unit then as just replacing the stock injectors beats the hell outta throwing in an extra injector into the intake mani. I do know that Speed Mafia was working on a direct port-like setup where he would use 4 injectors instead of one large one with the SMT unit. That could work well for a boosted setup as the stock injectors could still work as normal when the extra fuel is not needed.

 

Yup thats exactly what we're doing right now. once my engine arrives(This friday BABY!) it will go in and we will be testing it on my turbo setup.

 

you should finish it if you can...im tuning through an AEM F/IC and it arrives on wednesday

 

bout time we got some turbo 2.2s actually ON THE ROAD. Get times!!

 

LOL, yeah its been awhile since my cars been on the road. just a lot of misfortunes for me all summer long. Lots of family issues then roommate issues(gone through 3..). They all cost money =/ but its all good now! Should have this Turbalt smokin evos and wrx's here soon =P Then it will no longer be a turbo.

Hunter, ill try to finish that wiring diagram here today, thats all i have left. oh wait, your 07 arent you. If you can find me a pinout of your ECM ill make a diagram for ya. Today actually may not be a good day since it was a 3 day weekend for the navy. Gonna be busy today. PM Me or message me on AIM later today. We'll get you setup for an easy install.

 

pm sent

 

so whats you ETA on your pinout/wiring diagram sway? i picked up my UEGO and FIC today. also...i dont suppose you know how long the wiring would take? i want it professionally wired, cause thats one area where screw-ups can kill the engine. plus i dont have any crimping tools

 

you don't want to crimp. Go get a soldering gun, solder, and heatshrink. Butt-connectors have a tendency to fall off and let corrosion in. Might be ok for some neons, but not for a tuning device.

 

heres a perfect example why i want it professionally done...i dont know **** about how to do it...lol

 

Soldering is actually pretty easy dude. You get the gun, heat it up. You take the solder in one hand, the gun in the other, and press the wire onto the tip of the gun. It will melt it, you then touch the melted solder to the 2 wires you want to solder together. Its real simple. You then take the heat shrink crap and wrap the solder point and shrink it around the soldered wires to protect it.

I was going to email the crap i had home, but got so busy friday i had no chance. ill email it home monday and have it to you by monday night. That work?
