Thread: AEM EMS Series 2

Hey all,
I am soon ditching my chipped ECU for a standalone,

I was deciding between apexi power fc and AEM EMS s.2
Does anybody use the series two? I know its direct plug
and play which is a big turn on for me with ease of installation.

my biggest concern is can I run MAFS with it?

thanks everyone

you can run whatever you want with it, maf, map, tps vs rpm. Its all in the tune. I dont know how plug and play the series 2 is but its not all that plug and play. Mainly because of all the issues with the CAS disk not wanting to read on the aem ems properly so they made the 24-1 disk to eliminate those problems and then you have to setup the ems correctly to run it. If you dont know what your doing with standalones i wouldnt even try it yourself and would take it to someone who knows aem well. If your somewhat of a quick learner you can search through some threads to find out how you need to setup the CAS to properly read the disk, set ignition phasing and timing using the ems to match the map and so on. It takes some learning thats for sure because its all based on setup, if your using a single coil ignition, coil on plug, and so on. Once you learn what each setting means and stands for it gets much easier.

But it is far from plug in and go. lol But yes you can set it up to run different maf sizes which has you chose from a wizzard on what maf your running or if you run map you chose what map sensor your running and it recalibrates the maps accordingly. Stuff like that is simple, its just the initial setup and to get the thing to actually start is a pain in the butt even for those that know what they are doing. Both me and BenFenner went through the same thing doing it ourselves and both of us are pretty good with standalones, not experts by any means but we know our way around it and he helped me alot with some questions I initially had as he went through the same issue and he just did tons of reasearch and learning the system to figure his stuff out.

So I would think twice. Power FC, waste of money, its not an easy system to tune either and is a pain and not many people in the country know how to tune them properly. its more of a Japan used ems than anything. Very popular over there. If your gonna go with one, id do the AEM as there is way more people familiar with it in the states.

I had my aem installed and running in a little less than an hour and that was converting from maf to map installing a gm 3 bar map sensor and an aem ait sensor. You can run your maf sensor but why would you want to do that? Converting to map is way better. I bought the 24-1 cas disc but I could never get the car to run right so I went back with the oem cas disc. I have one for sale on the other forum check it out and let me know.

The MAF tune that ships with the AEM is useless. It has no power and is PIG rich. The MAP tune that ships was much closer and made way more power. Granted it was nowhere near tuned, but was much better than the other.

You can use a MAF, and you can get it to run quite well on it with AEM.

However, I would recommend going to a MAP+IAT setup, as there are many benefits, and few if any downsides.
