anybody used aem fic6 on 3.6 yet?

F/IC-6 | AEM

a buddy of mine suggested this to me, its not your everyday tuning component, this thing should only be installed and set up by somebody that knows what theyre doing.

so has anyone braved these waters yet?

Why are you looking at that? It's not really aimed at squeezing a little power out of a stock engine, it's a high-end controller for boosted and NO2 setups that require gnats-ass levels of control to avoid grenading an engine on the track.

Unless you're boosting there is no need for that.

When an aftermarket maker states this:

"..Misuse or improper tuning of this product can destroy your engine! If you are not well versed in engine dynamics and the tuning of engine management systems DO NOT attempt the installation..."

They are serious and unless you build modern high performance engines for a living [not just bolt CAIs on and cat back exhausts], you better believe what the warning says. It is a serious product for a serious boosted race engine. It isn't designed for a daily driver.

you have a jeep focus your attention and money on mods that address your suspension/steering and armor. The only money well spent on performance are gears and a simple programer (superchips or procal)

I live in New Jersey. theres no place I can actually go offroad. Maybe I can go to south jersey and drive it on the beach a little, I don't need a 4 inch lift and 37 inch tires. I do mostly highway driving. usually at a high rate of speed. the main reason I have a wrangler, winter sucks.

I occasionally run it at the drag strip just for fun, I would like to see more power out of it. SURE I KNOW its a jeep not a racecar blahblah your opinion is so much more important than mine, I know I know (aimed at whoever will respond to this, outraged at the use of my vehicle)

I've been piecing a turbo system together for the jeep, I need to do a lot of planning before I even try to start installing it. Right now im focused on getting the right programming.

im gonna try for 6 psi. I have a T3T4 turbo, nothing too crazy.

thank you. I guess you could tell that I didn't read that when you saw my original post, where I stated that this is a serious component that should be installed and set up only by someone that knows what they are doing.


not that I don't appreciate your feedback, just try to actually see what the original post says.

and not to pick on you specifically, this is aimed at everyone that responds completely negatively for no reason as soon as a post as made:

this is exactly why I hate forums. everyone is so quick to shoot down everything that someone says. make it faster? NO YOURE STUPID ITS A JEEP JUST MAKE IT TALLER WITH BIG TIRES AND A SNORKEL FOR WHEN YOU PARK IT AT THE MALL. gonna install a tuner for when you want to turbocharge it? NO THATS STUPID NOBODY DOES THAT YOU SHOULD GET THE $6K TURBO KIT AND BE LIKE EVERYONE ELSE THAT HAS MONEY TO BLOW.

if you don't plan to help, I don't need input from you guys. save your breathe and let someone that has the balls to be different answer my question.

speaking of the original post, I asked if anyone has USED IT. I didn't ask for bland generic "me too" answers suggesting the tuner that all it takes is a google search to find. If nobody reached out and tried something different the aftermarket would remain just as limited as it already is. enjoy your tuner that plugs in predetermined numbers.

Even with a turbo I don't think that controller is a necessity.

so I can just throw a turbo at this thing and the factory computer will handle it just fine then? no check engine lights? it will undoubtedly be at the maximum possible power to make the money spent on a turbo set up worth my time?

Here's my take on it, take it or leave it. You're looking at a high-end engine management system. It's designed for a pretty dedicated track vehicle. For the kind of modifications you're likely to do to an engine like the Pentastar, you can just get a custom tune from any of a hundred shops that do this sort of thing for a living. With this controller, you're basically doing the tuning yourself...a lot more work and at best you'll match what the pros can do. At worst, you nuke your computer and/or engine.

Your first step is to figure out exactly WHAT you're trying to do and what you want to achieve, because your last post really makes me wonder.

For the record, I have no problems with building a JK to go fast on a track. I just don't know if this is the right thing to help you do it...it might be, but it depends what you're really looking to do.

I'm also curious if it'll even be able to talk to your Jeep's computer, since the engineers have been doing this stupid "let's use a totally new encryption on the computer every year" thing recently, and it's taking the tuners (like Diablo, etc) a couple of years to crack. This is a piggyback unit, not a standalone controller.

this is a detailed response, rather than a quick and total shut down. that's much more appreciated.

I have a friend at a speed shop that suggested this to me and he wants to do the install and tune. my problem with the cookie-cutter tune is that we would have no freedom in our own tune. the aem enables me to not only cut back on injector timing (so I can install rather large injectors for the high rpms to be fed properly) and the timing can be delayed/advanced. while this system is meant for a dedicated vehicle, it can be used at less than full potential, while being $200 less. I was hoping somebody would have tried this before to speak of their experience whether they could tell me they grenaded, or got power gains, or it just plain didn't work. maybe a little insight on the tune setup they used.

im probably going to install the aem first, tune it best for N/A, maybe with the larger injectors (tuned down throughout the range) so that when turbo-time comes im already set and ready, ill just need to re-tune for forced induction.

on a side note, aside from the tuners on the market, has anyone found a way to increase the throttle-by-wire action? im used to cable operated. this is my first non classic vehicle. when im going up hill in 6th, and i press the pedal harder, i expect it to push harder, at least SOUND like its trying to go. i cant stand the fact that the jeep decides for me that i don't need more throttle, it says "nope im fine right where i am"

Ok, that makes more sense...a lot of people who ask about products like that are the same ones asking LOL WHICH CAI GUYZ so that's where I start from.

It sucks that Chrysler goes to such lengths with their encryption...a custom tune is no big deal on most vehicles and gives you the level of control you're looking for. I don't know the specifics on the TBW delay, but supposedly it's intentional to keep people from making a mess of things on rocks. Makes sense, but they really should've made a way to disable it. There's got to be a timing setting somewhere in the programming.

Please don't take it that I am bashing your idea...just looking from another angle. I guess if I was just wanting "fast"; I would seriously look at converting to a proven platform.....LS3 or LS7. we all know that 600 to 700 RWHP is real easily do-able with one of these engines. The Pentastar 3.6 has yet to be proven at high HP for durability and longevity. Undoubtedly some one can get the HP numbers up there with it; but we don't have any idea how it will hold up. Best of luck to you.

The dbw throttle systems are not only controlled by your foot, but are also controlled by engine RPM. So, in other words, if your engine is not building RPM's, the throttle isn't opening up any more. And it will not fully open until the engine is near peak output RPM. This is one of the big reasons that CAI's are a farce with modern engine control systems. The restriction is NOT the intake piping; but the throttle itself..........that is how it regulates engine RPM......restricts the air flow!!!!

thats exactly why im straight piped but still have a stock airbox, a CAI or "ram" snorkel with 3 or 4 90 degree bends isnt going to help at all when i cant even make the thing open up all the way. im wondering if anyone has figured out a way to intercept the signal in TBW so that it will open a slight percentage forward, or at least advance it so the computer thinks otherwise or idk what. basically i like carburetors lol.

this is a grey area in my knowledge base, i just know a bit more than the average 14 year old kid dreaming about getting a civic. everything i build is carbureted

I know who I'm asking when my Vette's acting up. Carbs are like voodoo around here, and few of the local shops know any more about them than I do.

i have a 77 vette so i can offer a lil advice on it. the first time i pulled the carb there was water in the intake manifold so i quickly replaced the 80lbs rusty iron manifold with a cheap unfinished summit racing dual plane manifold and a holley carb (750 cfm electric choke) takes a lil tuning to get it right out of the box but nothing special. i usually go straight to a better carb on any vehicle that i have carb problems with. sorry for goin off topic but i thought id throw it in there for you. good luck with the vette
