I want you to tell me all about the aem ems standalone. I'm looking to build my motor over the winter and run approx 20psi. I'm looking at using this standalone as there are just too many quirks with the f/ic. I also saw on your website that you have exclusive idle control. how does that work? I want to know things such as:

cost/time to tune
does it have target afr's
what things do i need or the is the stock ecu still used for
do i get a cel with the stock ecu not reading the sensors
anything else you want to include

 

why didn't you just PM him?

 

because i figured some other people might want the same info

 

Consider this.

I have AEM and I love it.... im not the obne to sell it to you but it has tons of options... talt to a sales rep they would be able to show you its capabilities alot more than anyone in here...... ITS THERE JOB...... you night wanna look at other options too like Hydra EMS or Apexi EMS that alows you to tweek in real time

 

Idle control is done via an IAC system that can be manipulated through the AEM

Target AFR closed loop tuning is available through the AEM EMS.

Stock ECU to control CAN/BUS system for gauges, multi-plex for center counsel options and security system.

You will get a CEL through the OBD2 port, but not visable on the dash.

 

Is it true that AEM will not warranty this product? I hear that support is lacking - this is from others on this board of course.

 

No. AEM will warranty the unit, but it must come to us first and set up through us. AEM is fully aware of we do, and supports it primarily through us.

 

Very good info to know.

 

well i found the thread of the back and forth discussion of the aem and the hydra. i think i have decided on the hydra. my question is, with the hydra's autotune feature do you have to go to a tuner? or will it just do everything itself?

 

The autotune will get you close, but not 100% and that will only correct part of the fuel issue, and this still leaves the ignition side, which is some of the most important data. Not to mention with the AEM there are about 100 sub windows almost infinite adjustment to tweak.

 

so no passing SMOG then?

 

VERY doubtful with any of the units out on the market.

 

You mean with any of the standalones, right? My F/IC passes smog just fine...

 

Standalones, correct. I should have been more accurate in my statement.

 

only down I say for the hydra is the speed cut, for a standalone they should have considered removing the speed cut.. at least not at this moment

 

I have a way around that now...

 

Full Idle control not exactly. A/C doesn't work. You do have full VVTI control, full ignition timing control, and full fuel control. I would like to hear directly from others that have purchased this and tuned by AEM certified tuners and what issues if any they faced. If the tuner sets the idle below 1,000 the car dies due to the voltage at the AEM ECU drops below the threshold of the unit it shuts the car off. The A/C will not work at all with the AEM plugged in. I am waiting on a message from someone on the board for the A/C fix. They said it was very easy. The voltage issue might be due to four items feeding off of the OEM ECU power wire. I am planning on separating these.

 

this something we all could use? Or specific to your location?

 

on a hydra?
