The aem series 2 does not have a built in wideband controller like the 1052u series 1.
I have the aem inline wideband controller wired into the ems and airfuel is read through my aem serial gauge.

You need that with the series 2 In order to be able for the ecu to get o2 feedback to run close loop for better gas mileage.

I'm also geting an oil temp, oil pressure, fuel pressure sender wired I to the series 2 so that the serial gauge can displays everything

Thanks man.

 

E-manage ult, for its factory OEM system reliability retention, wile offering all the key features of a full stand alone, wile still smog legal, and costing less then $500.

 

AEM here although you are good using AEM, Haltech, or Motec honestly. I have a haltech sport 1000 in my wife's miata and love it as well.

 

Aem v2 and im using innovate wideband

 

That will change very very shortly, same developer but now called ktuner

 

AEM V1, I have had hondata on both of my previous Turbo integra's and it is also an awesome product.

 

when is this happening?

 

I have the Haltech Pro Plug In ecu on my car. As far as the features go,

- Haltech offers VE tuning as opposed to tuning via injection time on AEM series 1 and 2. Haltech supports injection time too if you wish to use that instead.
- The main tables go as far as 32x32 which offer more resolution than AEM
- The pro plug in ecu comes with a built in map sensor. It's a 1.5 bar map sensor so if you don't plan on going beyond 22 psi you're good to go.
- Haltech offers a PID controller for various functions including the idle air control valve, the wideband and the boost controller.
- The pro plug in ecu currently supporst the fuel composition sensor (I know AEM series 2 will also support the fuel composition sensor on their final update of the AEM tuner software).
- The pro plug in ecu also stores trouble codes and has control over the check engine light.

These are some of the advantages of Haltech in my opinion. I'm sure I've missed other small features here and there. Honestly though as a tuner I can say this, pick the tuner first and ask them what they're comfortable using. There's no point in bringing them an ecu that they are not familiar with. A tuner will perform their best with something they're comfortable using.

 

Series 2 baby.

On a side note, how is everybody mounting your Ems? I was thinking about making a bracket to mount my series 2 in the stock location, might make extras if people were interested.

 

AEM series 1 for 10+ years, no problems.
