AEM vs Emerald vs Other - The debate

Ok guys,

 

A thread for the clever guys.......

 

My engine build is nearing the stage that i have to start thinking about popping it in the zed.

 

I will be running a chipped ECU for the running-in period. I have an AEM EMS which i will be installing afterwards. I will be running dual intake with a 3.5 bar MAP sensor.

 

So, i've looked over a squillion old threads which has raised some questions.

BAZZ for example, switching from AEM to Emerald...why?

 

What are the pros and cons of each? AEM seemed to be the muts nuts in the past, why does it seem this is no longer the case?

 

Over to you.............

They all do pretty much the same job really, just comes down to cost, features and local expertise.

 

There's not much wrong with the AEM other than the sensors are usually miles off calibration and the mapping software is awful. It's a re-badged GEMS unit.

 

I use emerald for a few reasons but mainly because the service is 2nd to none and price-wise its hard to beat. Think that if you go to emerald for the mapping, you have access to the people there who design and build the ECUs!

For example, they have now done a firmware to read the 300zx CAS directly after I nagged them for a while.

Another BIG plus for emerald is fixed price mapping, £275 to map it is cheap and Dave will usually sort out other issues too without charging extra. In the past he's even machined up new spindles and all sorts for customers.

Thanks for that John,

 

I bought the AEM over a year ago and it seems that the Emerald system has come to light since then. Had i been in the market today i suppose the Emerald would be the best bet. Do Emerald supply all necessary sensors aswell?

 

Other than the MAP sensor, are there other AEM sensors i should be using? You say they are usually miles off calibration - will the stock sensors suffice?

 

The guy who will be mapping the zed for me has experience with the AEM so hopefully i wont have a problem there.

Is it series one or two aem you got though as there is quite a bit of difference and this would affect what is better to run with
