I have the ems system and I am currently spending every waking moment trying to figure it out! I REALLY want to know it, so I have been reading up on every aspect of aempro and I have been getting acquainted with mine, trying to figure out how I am going to get my engine dialed in (if my engine ever gets done!). I am just wondering who else on this board is running this system, and if anyone has tackled this system themselves, instead of having a tuner do the work. Where did you start???!! I will be learning the system, probably asking a lot of stupid questions, but no doubt I will get it all figured out!! If you guys know of any links to AEM EMS related info please post! Thanks.

 

Well what about the AEM forum. There AEM techs can answer your questions.

 

are you playing with it on a car now? thats the best way to get started with it...as long as you have a pretty good idea of what you're doing...the tutorials on the aems forum are good enough to get you driving. be careful though cause you can break stuff pretty quick if you dork with the settings...mainly watch out for the timing and fuel maps. dont lean her out and dont get the timing out of whack

 

Yup...AEM has a great forum for you guys. Just go to their homepage.

 

Yeah, I have been reading hella posts on the EMS board! It is somewhat over my head right now though. Some of it is at least, I am getting to know it somewhat. It is badass to say the least.

 

I read that board for a while and that's what convinced me not to get AEM right now...it's over my head at the moment.

 

I have been looking at the site also cause im looking for a good base map for a turbo gsr.For some reason it wont let me into the forum where the base maps are uploaded.Where else can i get base maps from?

 

You have to register your AEM with the serial # and stuff in your profile on the forum I believe.

 

done,man its hard to find a base map for anything over 440cc injectors.

 

There is not a specific map made just for one perticular motor setup. I usually look for the closest map with correct setup instead of poking at injector size or Psi the map was designed for. If you look carefully at vortech supercharger map and compare it to 440cc type R turbo map, you will find great difference in the shape of both fuel and timing curves. Then you modify from there. Now a days, I just start from scratch since no file is really trustworthy. It will run your car but will it correspond to the exact setup you have? no, one in a million.

 

Yea i know it there every map is different.Im just looking for something close to my setup that i can just fine tune or atleast be able to start the car and drive it without boosting.

 

There is 440cc Type R turbo map available at AEM EMS forum. You must have a unit or at least a serial # from the ECU and register to go in the Base caliberation section.

 

yea i seen it,its the aem tech's map jp i believe.Should i load the map and change the fuel pressure and injectors size to the inj's im running and then fine tune from there?

 

yes you should do that but remember JP has different cam setting. I believe he dialed +3 on intake side.

 

Ok sounds good,since i have aem cam gears.But what about the turbo's does it matter that they are different?

 

W3rd. All the JRSC maps that I used were pretty crappy. I had to use one and basically start from scratch with some of the main points like fuel delivery and timing.

 

Hey falcon,can you street tune the aem system if your using a techedge wb for part/full throttle?The only tuner in my area has never used the aem system before.He said he went to the first aem seminar.I need to get an ems but with no tuner im stuck unless doing it my self.

 

That's too bad. I think results with base maps vary from car to car.

Here's what I got from one hour of dyno time from a JRSC Civic Si base map.

 

I wasn't concerned on the correct HP and a/f on the dyno using the base maps provided on the forum. What I was concerned was the drivibility of the maps on the street. To get a pretuned base map to run the way your car should is rare. Lots of changes has to be made at least that's for me on turbo vehicle. The size of the turbo, the way it spools, the mods on the motor all contributes to the driviblity. A fuel or ignition map may curve correctly with a example T3/T4E but is way laggier on a 60-1. Supercharger is probably easier to find the correct map since there is only two types ( from what I noticed) of chargers out there and they have no sizing differences.

i'll go to the dyno when i am done tuning.

 

Yeah I would imagine a turbo would be more difficult. Roots blowers don't really change the shape of the powerband from stock very much, the numbers just get higher.

For a start on drivability what we did is hold the car at 4000 and 3000 rpm with the dyno's brake with no more than 40 load and tuned the whole lower left hand corner of the map from the rpm point we had the brake set for. That got me pretty close on streetability. I need to mess with the accel settings next. I get a little hesitation when I give it a lot of throttle all at once.
