Apexi Power FC vs AEM EMS

I am considering a standalone engine management solution, and I do not have experience with either systems. I am in the process of researching both systems and comparing them however I would appreciate some input from people that have used both systems.

Thanks!

What specifically do you want to know? I’ve owned both systems and tuned both systems many many times.

Basically capabilities between the 2 systems and pros and cons. I noticed the Power FC costs $500 less then the EMS. Is the EMS worth that extra $500?

Understatement of the year…

haha, nicely put danno.

In my newbie opinion the AEM EMS is better value for your money regardless of the additional cost – but it still comes down to budget. The PowerFC does what it does well, but it does a bit less and more importantly, it’s a lot more difficult to make it do what it does - the AEM is tuned via Laptop, the PowerFC is tuned via Commander and its extremely annoying and time consuming

with the additional 500 your saving tho, you can buy the datalogit kit for the pfc and then tune via laptop

you also get wuite a few extra features with this kit

I’ve owned both.

Starting with the PFC - I was totally new to tuning and I’ll be honest, wasn’t sure what I was really doing. I spent (read: wasted) countless hours trying to tune it, learn it, etc. Even had a friend (who owned an AEM) try and help me with tuning it but the units on the maps made no sense (apparently Apexi uses some sorta unit for load points).

I only owned it for less than a season and I was happy to get rid of it for an AEM EMS.

After I bought the AEM, and spending some time with a friend tuning it, I’m glad I went to AEM.

Now both are powerful EMS and there are high HP cars running PFCs as there are AEMs.

But if you want my opinion: AEM EMS (and I wouldn’t trade it, even for a PFC w/ Datalogit).

In the right hands, both systems will accomplish the end result, which is to have control over your motor and upgradability down the road.

both have great features. aem has a bit more.

if your budget allows it get aem if not then apexi.

well said radick…

and the number one reason aem is better …a power fc wil not eliminate your maf without buying the special version for more money… and then u still need datalog it to tune with a laptop and it’s not even by apexi you have to buy 3rd party software and hardware to do this…what a waste of money. i had a power fc for my Drag gtr basically i sold it they just don’t do what i want for the car.

I guess in the end, the AEM probably works out to be cheaper and if anything, it’s “better” as well. But I won’t get into that debate.
