I am familiar with ecu flash, I was wonder in a tuning aspect how aem works, it is just like ecu flash with more options.

Don't I just install the aem disk plug it into my computer then from there it is like ecu flash kind of..

Pretty much what I'm trying to say is, can I figuare aem out if I understand ecu flash?

 

Anyone?

 

I have a AEM v1 on my evo and i love it dood!

 

If you understand "tuning" in my opinion AEM should not be too difficult for you. It definitely is different and takes time to learn but I feel its very easy to tune with.

Are you thinking of going with a Series 1 or a Series 2 AEM EMS? For Series 1 I will tell you the base calibration may not even get your car to sputter, its not close at all. Series 2 using the wizards starting from a base map it will most likely start the car but you will need to dial it in obviously.

 

From ECUFLASH right to aem... you will be scratching your head.

Just read the user guide 7 times and you will catch on.

I love the AEM.

 

another vote for AEM

 

AEM count me in.

 

Ive debated going AEM for awhile, mostly for the ease of dialing in injectors, and flash knock isnt as big on an issue as it it with the stock ecu on 2.4l

 

my car runs 10 times smoother on aem. only down side is start up takes a couple cranks

 

AEM is so nice boost comp is amazing

 

Not to presume that I know wtf I'm talking about, but my car took a few cranks on ECUflash until I lowered the Injector start IPW. After that it fires right up.

Does the AEM have better overall control of the car than ECUflash? I guess I mean does it give the end user better overall control? I.E. the idle control (warm and cold) dial in. Does the tuner get 100% control of it? Also can the AEM do SD?

AEM or Haltech for highly modified cars is better in every single case I have personally seen, period. If you are talking about a mildly modified car 400'ish who on our dyno the stock ECU works very well. Yes, I am aware of the power that has been made on stock ecru etc., I'm also aware of the downsides in drivability and am no longer drinking the Internet koolaid about how great they run and drive at those high horsepower levels, as I've not seen it.

 

AEM + Sparktech on E85 and my cold/warm starts are smooth, quick, and strong. Wouldn't go back to stock ECU for anything!

 

I agree 100%. You just have to have more tuning knowledge to tune AEM is all... From cold start settings to the no dummy proof knock counts that are already setup for you from the factory ECU etc.

 

I won't say I don't agree but....

The stock ECU has come a long way. The problem, the way I see it, is this. The stock ECU works really well. Everyone here knows I use to only recommend stand alone engine management for any type of 400+ whp build. Those days are no longer the case, I use the stock ECU 10 times more often now than any other.

What we have now though is a lot of things in the ROMs that have been added or discovered, the stock ECU is more like a stand alone everyday. The problem is there is no "help" menu to tell you what each of these added or discovered items do. All the aftermarket computers have something to lead you down the right road. Some of the items in the stock ECU nobody knows what they do and are basically labeled that way. I'm not bad mouthing it, the stock ECU is good up to a point. I no longer fall for the "perfect stock drivability" crap on these big HP builds on the stock ECU. I've seen the experts do them and then I've seen the issues after they are done. I'm not buying that stuff ever again.

So, I think because all after market ECU's have an actual help menu and everything in them is labeled and functions correctly, they run better, are easier to use and are easier to learn. There is no manual for the stock ECU. There are HOURS of research here on EVOm, learning how to patch ROM's for the next round of things you want, learning how to update XML's etc. It is very tiring and hard for someone who is not real computer savy, which is a lot of people.

My huge and sincere thanks does go out to all the guys who are involved in the stock ECU development though, they have brought it a very long way and it is a great tool because of all of them and their hard work.

As an additional side note. I've run quite a few ECU's now and I am going to say that I feel the Haltech is by far superior to anything else I've tried. My car makes over 700 whp and I can say that the start up, idle, drivability etc. are as good as any car I've ever seen. It is quite incredible actually. Granted, I have a lot of time in it but I've put MORE time into other ECU's, including the stock one through many different cars, and it still runs better than all the rest. There is just no comparison.
