Which EMS does everyone seem to like? I've been browsing around trying to pick the best for the buck. Not exactly the bang for the buck, but all around performance and safety (for the engine components)

 

piggybacks are good but have limitations. I like AEM, because I've seen what it could do, not only on FI cars, but basically on all models that AEM makes. Complete control if you have the tuner who knows what to do with it.

It's amazing how much improvement you could make with it on your car.

I think s-afc is good too, been around for a while and XEDE can't be argued that much on how well it perform compare to the Full non-piggyback EMS.

 

standalone choices (AEM (own knock control by sampling the stock knock sensor at the time of ignition and or a constant raw value), Autotronic (no knock control though))

Piggback choices (UTEC, Xede) = (uses the stock ecu for knock control but you can over ride with your own settings.)

These are pretty much the pick of the litter

 

not too much choice on the stand alone.

 

from what i have read aem is the best . an d 68 percent agree with me

 

AEM is good, but S-AFC IIs cost a lot less

 

Wow, it seems the AEM is the most popular (when looking at the poll). What is the cost of the AEM (1st place) and what is the cost of the Vishnu XEDE (2nd place)

You need an option for the HKS F-CON VPro. I'm hearing good things about it.

 

The fact is that 99% of the people out there don't need anything more than a SAFC. I think many people jump to a AEM or other standalones way too fast. Just like I think many people dump the stock turbo way too fast. **** I would love to sell most people big turbos and standalone ems but the fact is most people skip the most simple steps. You can go very fast on a SAFC with the stock maf.

Overall though if you are talking about the best on that list I will say the AEM EMS. Bang for buck Apexi SAFC.

 

SAFC works well but not as well as a Tuned Flash or Piggy back with timing control as well as A/F control.

 

Amen.

I've seen several such nightmares that were the result of a lot invested, but yielded little power with a lot of headaches. This is the result of performing little research and taking bad advice. The only thing going fast was the owner's money.

 

Do you say 99% of all car owners all Evo owners. Most of Evo owners are modded up and would benifit from the AEM or other standalone. When I had a SafcII The car ran OK now it runs a whole lot better. The stock turbo is a great piece but the fact remains there are no 600whp stock turbo cars out there. If you want big hp you will need a bigger turbo so a lot of people myself included realy dont want to waste time with a unit that will be replaced.

 

Well yeah if you are shooting for 600whp that is a whole different ball game.

and yes a well setup AEM EMS car will run incredible.

 

But yes you are right you can go fast with a SAFC and the MAF. If you have limited funds. You can always take it in steps and heep upgrading until you are happy with the tune.

 

Apples and oranges.

Most people will never see 600hp simply because they have not the desire, funding, or impetus to get themselves into that arena and the responsibilities/expenses/potential headaches that inevitably accompany it.

The fact is the vast majority of EVO owners who mod their cars will likely never attain the full potential of the stock turbo. While the safc may lean toward the simple and cost effective (read: limited capability) end of the spectrum, the next step is not necessarily an EMS.
