AEM EMS training tips... - SRT Forums

I know a bunch of us have been waiting for tuning videos from "drifting.com" and it looks like they may come out with something in 2010. How about some of you smart guys just do it for us? I know there are some really smart EMS guys on here. I would be nice have a quick overview of the basics. It would be a huge help to us newbies.

Here is something one of the old boosted mopar guys did for us mid 80's car guys.
YouTube - Introduction to dcal Part 2

That quick video is really helpful when messing with the old school cars chip burning tunes. I'd love to see an SRT4 EMS video. I'd make a video but then everyone would have a blown up car

There are special secrets that a mere mortal wouldnt be able to handle...

God this would be so nice to have...

What I don't get is why AEM doesn't put something out. You would think they would have something to help sell their product. I can understand custom tuners not wanting to give away their tricks but AEM should push the use of their product.

I agree with that!!!! i know some things just take practice to do also but reading all these how-to BOOKS dont do sh!t for me.... I need a video.
Even if some one through together some small ones and sold them for 5bucks a piece.... youd make a killing. even if your not a pro and just making a simple vid on setting up traction control thats cool. ill send you a 12pack

its in the manual but not in plain engrish, try to read my post on actual PW and you may get some insight on how these calculations are made, for the first year i was banging my head against the wall trying to figure out how all the functions relate then i took the time to print the manual and actualy use it as a self teaching guide while I had the program open

ohh yea read the AEMpower forums there are MANY hints as to the stratagy

well when you figure something out post it up, if we all put our heads together it should be simple

i think some good old fasioned team work will put things in perspective

What you really need is how to initially set up each type of fuel map (cell by cell, hybrid and full boost comp) and the base ignition map. A short how-to on how to adjust each after its initially set up, and most people would be able to figure out the rest.

No one really seems to want to help when you have a problem. You normally just get the "bring it here and for $950 i'll tune it for you"

That is true!!! where do we start??? i guess the basics.
I myself have a small mod list ,
AEM EMS
DCR Oil Mod
Cold Air
BFMIC

i do have 50trim sitting here and still need a few parts but i nervous about putting it on cuz i dont feel i know enough about the EMS to put her on and i dont have the money to blow it up....

So to get this moving along im gonna ask questions then make a small How-to vid on it when i feel i know enough to make one... and Nutz i know you have enough knowledge to make a few..... SO first one

So i finally got my car to idle 800rpm with a 13.5 A/F
I CANNOT get it any leaner then 14 without it missing and running like crap.

What does everyone else got going on for RPM? and A/F? at idle?

to do this i first let the car come up to temp then turned off all trims(fuel and ign) made sure the fans where not running and nothing else was on or running that would put a load on the motor....
i simply selected the bottom 4 cells on the fuel map that idle was using and hit the minus botton on the keyboard untill it was around 13 - 13.5

i'm not sure if this was the correct way but if it was ill make a vid on it.

Now one question is this.
if you click on the Idle icon in AEM Pro it will bring up a few windows and one of them is "Idle% Vs Target Table"

In that table i was told to move the line until the "idle learned value" equaled 0 or slighty higher but when i did this for all RPM points the engine would die after letting off the throttle (coming to a stop light) or the engine would not start at all.... ALSO the engine idle would be set at 800 but the idle would be around 950 - 1000rpm...... What i did INSTEAD was put the "Idle Target Base Table"
to 800 rpm and moved the line on the "Idle% Vs Target Table" untill the idle was at 800. Does any of that make any sence?? or correct?

ohh and anyone using AEM Tuner yet?

raw X mb/sec X boost fuel correction table %= PW (most important #'s)

PW X throttle correction % X any other fuel trims %

= actual final PW .

its just a fancy calculator

I posted some examples of interpolated maps in the actual PW thread they should give some good insight

I've had this EMS for maybe 2 years now, and i look at your post and scratch my head.

I've had the car at 3 different tuners, and to be honest, the person who did the best tune was me. But for me tuning it it was all trial and error. I have it running quite well now, just screwing with the ignition map. Mind you its taken forever to get it where it is, and its no where near complete.

I HATE the O2 feedback. It takes forever to get to the target afrs and jumps around way to much. I wish they made that more user friendly.

yea I am horrible at explaining things in writing but if you try to do the calculations I gaurentee your gonna go OHHH thats simple

if your O2 FB is jumpy turn down the gain (for O2 feed back) this will make minor adjustments

IE: if the gain is at -0- the feed back will try its hardest (you will get 100%)to get you in those A/f's if the gain is set at 50 (it will use 50% fuel correction) it will only use half the fuel correction and will not overshoot, you can also fool with the O2 feed back rate and slow it down (larger number) so it samples less often

Damn good info. I vote you make a video

I am the same way. I dont' retain the shit after reading it. Most of the time my mind wonders off while I am reading it, thinking about something better to do. I learn much better hands on or watching a video of someone doing it hands on.

I understand what you are saying. My problem is I don't know what most of that stuff is. raw, mb/sec, other fuel trims?
