which ones better to go with??????????? which ones easier to use????????? i cant make up my mind!!!!!!!!!!!!!!!!! im goin krazy......

 

I asked a similar question. Never got a straight answer.

 

i kno everybody tells me the pfc,but them ill hear the aem is btter. i just dont wanna make the wrong choice.
if ANYONE has any insight on this plzzzzz help out!!!!!!!! still

 

Rotoboy, consider this.....you live in Palmdale Calif. which means that more than likely you will be going to Tri-point in Ventura for your dyno-tuning needs. Keeping in mind that they will tune/trouble shoot primarily with the PFS Purple, since they like it so much, you might want to consider that as well. If you take your car to XS Engineering, they love the PFC. Just food for thought.

 

Based on what I've heard, not first hand experience or research, the AEM is much more difficult to dial in. I believe a couple people have found that the "base map" is very lean and the seq turbo control system needs a lot of fine tuning. I've also heard that getting the car to start when the water temp is not in opreating range is problematic with the AEM.

I think most of not all of these issues could be resolved with the correct tuning/settings. Finding a shop that is well versed on the system is another issue.

In the end I think you have to ask yourself what you need. If you're not running a lot of boost you probably won't benefit that much from a map with more resolution than the PFC, more versitile fuel system control, aux outs ect.

 

thanx bro ill take that into consideration. but **** man tri point charges alot for the whole aem unit plusss tuning, and dyno time, u would think that it should me cheaper , but i guess its all a plan to make profit from their loyal cusomers. but they are a highly respectable place, dont get me wrong< their just a lil pricie at times!!

 

Pricey sometimes ='s reliable/fast

skimping = blown shiet

 

Look at it this way. Every AEM I have sold, the customer has wanted to return it for the Power FC.

Really? Thank god I seen this thread then... was thinking of getting one. I heard the AEM was good on piston engines (little more forgiving)but I never heard about the Rotary... No wonder everyone is using the Power FC....

 

AEM = rice
PFC = nice

 

AEM is a great product, but you really need to consider your budget. PFC has tons of maps that can be used with the datalogit. AEM is newer and not as wide spread, so plan on lots of dyno time which means lots of $$ unless your local shop is already using the AEM system.

 

AEM is hard to use. Bottom line. If you have someone to tune it, your are alot better off, but its still probably very unneccesary. The FC has been around forever and proven. And i dont think you will be running 9's anytime soon, so stick with what works.

 

I'm sorry Jason, you're wrong... I bought an AEM from you and I still have it and I never asked you if I can return it So if nothing else you have 1 Custumer who didn't want to return it

With the AEM you can do things like Nitrous and Water Injection according to whatever throttle position and Mass airflow values you want to align yourself to... that and no BS Datalogit and "Authorized" Tuners that rape you up the ***, is why I bought it and I have yet to sell it... I can't say I'm deleriously happy, yet I can't say I'm pissed, when It was tuned, it performed very well, for the 4 Weeks I had it working and theh wrecked my car...
Now I'm waiting for a rebuild because I was too impatient to wait for it to get tuned on my new car with the same mods... I figured how far can it be off !? -> Answer: FAR !!!!

So take a look at the features you'll use, e-mail AEM, go to their forums, talk to PFC people here in the PFC forum and make up your own mind, just cause everyone uses PFC doesn't mean there issn't room for improvement...

-DC

P.S. whatever you do do NOT rely on other people's maps, with the exact same mods they might have 20KMi more on their Injectors, and therefore yours might flow better or (Worse) Worse... since if they don't you lean out and blow your motor... ALWAYS Figure on Dyno Time... weather you get it for free or pay for it, D Y N O T I M E = Money Well Spent...

 

Ok my bad, all but one

I had a similar issue when I bought mine, but ended up going the PFC route because of availability of tuners. The ECU is only as capable as the tuner, and there are many more capable tuners of the PFC than the relatively new AEM unit.

 

Sooner or later I will be going to AEM.

Last week I got done talking to Tri-Point about the unit. They pretty much have it all figured out. It took a bit of time to get it to work well with the stock sequentials.

But they are liking it and will probably start tuning with it exclusivly(sp?).

Right now, AEM isnt the best route, but in the future when tuners have more experience with it, I will get it.

 

HMMM...food for thought thats for sure...lots of valid points

 

It's about your application. What do you want to do with your car and how far do you want to go?
Seriously, be realistic and determine if you want it to be a street car or a track car or both based on what you have now or the immediate future (don't space out and think about a 20B next year like I do after a few beers).

PFC will be a whole lot easier to pick up and understand. You may be able to pick up some tuning while you're at it. There is more PFC familiar tuners as well as support like the forum.
You're better off the PFC based on the questions you're asking.

I chose AEM because of the programmable options. I understand some basic tuning and how the software works (not all the details, but some). The AEM buyer probably is best fit by one who knows exactly what they want with their car and want the programmable aspect of the AEM (water inj, n2o control, etc). It is a powerful EMS, but do you need all of its capabilities? Most guys I know opted for the PFC for simplicity and support.

Like most products in the tech field, the more capable and programmable the product may be (like digital oscilloscopes), the more complex it is to operate/set-up or learn.

From my experience.. aem is great but on a fd it sucks because our sensors are so old you never get a decent reading for some reason.

 

Not getting a decent reading from the sensers... technically, if you had misleading sensers you would get the readings givin to the whatever ecu(powerfc or aem) then it wouldn't run at it's best performance anyway.

 

the aem is alot more sensitive though, if you are not getting perfect readings from the sensors it wont read at all almost. With the pfc its alot more leanient.

 

I heard the same thing from a shop in Phoenix. Go with the PFC

 

Ahhh got ya...

 

Apexi Power FC all the way

 

You should search this topic, i'm sure it has been posted here many times before. As for the PFC, its been very reliable for many people and its a great buy. I dont know too much about the AEM ECU, so you should search about it.
