Standalone auto NA-T


Picoto

Recommended Posts

550 bhp on NA-T requires a proper engine management system.

 

I would contact SRD for an expert opinion.

 

When I ran 530bhp on my first single turbo, I was on AEM .... switched to Syvecs after 2/3 years.

 

ECU is an important element in a single build

Seems mixed opinions on these EMU Blacks, some people say they are very good some say they are shit. Would welcome some feedback on how you find the features and the interface for setup and mapping etc.

 

Budget dictates where you go with Standalone, lower end your at the EMU Black or Haltech range. Avoid the Link IMO as I found the interface garbage.

 

Top end Syvecs every day - the safety features are worth the price tag alone and saved my built engine twice! for a NA block you can replace for little money not so sure its worth the added expense.

I changed from a AEM V2 to a EMU Black, the V2 is a fantastic ECU for the 2JZ with the ability to run the automatic gearbox but the EMU is much more modern in terms of interface, DBW options, support and accessoires. The main disadvantage of the EMU is a lack of ports in my opinion (even worse in the Classic), you lose an additional 4 H-Bridge ports to a stock IACV for example so a DBW setup is almost a must. That does give you the option to use TC, cruise control and launch control as well though. In the end you should choose an ECU that suits your application and your local mapper/tuner/dyno guy is comfortable working with.

EMU doesn't support automatic, right? I presume you are manual?

 

Consider the Proefi ECU, it supports auto and has plenty of modern features

I've tuned with EMU's, Link, Syvecs, Haltech etc. All of them are more than capable of running a 2JZ in an acceptable manner for road/track use, although some will exceed in some areas more than others. Some of which will never be noticed by the end user.

 

Trying to identify all the distinctive differences between each ECU platform is quite a challenge as there is a lot of areas to cover, but If I had to try and condense all the differences between each platform I would probably hone in on the fact that the cheaper ECU's are more focused and less flexible, both in terms of hardware and software. This can be a good or a bad thing depending on what you are trying to achieve.

 

The high costs of a high end ECU like a Syvecs or Motec really comes with it's ability to really get creative with the setup of the tune and being able to have quite complex control strategies which can be adjusted at a very granular level, which may simply not be available on the lower end ECU's.

 

For example.

 

Using an EMU Classic, it has closed loop boost control which works fairly well and can be adjusted, but only allows for a limited amount of inputs to allow it to change from one boost map to another.

 

A syvecs on the other hand, you have more boost control settings than you can use in most scenario's, and has a huge array of calibration switches that can alter or target different boost modes. If that wasn't enough, you can then dream up custom 2D/3D tables that can take almost any variable thats available to the ECU in order to alter the way to boost control strategy works.

 

This example can be seen with most features on a high end versus low end ECU.

 

I'm just happy that in 2020, even the low budget EMU classic/black are miles ahead of piggybacks and old standalone's like Greddy Emanage, AEMV1, PowerFC etc. In my opinion there is not a lot of justification to run such old hardware these days.

 

My recommendation for finding a standalone is:

 

a) Define a budget that includes ECU, sensors, labours and mapping. Usually double whatever you plan to spend unless your car is already well sorted and ready to go.

 

b) Define the requirements of your car & needs. Do you want just a road car that goes from A to B, or do you need it to sustain laps round a track. Are you happy to just get in it and drive, or do you want the flexibility to change the various modes of how the engine performs. Do you want lots of safety features setup? Do you want to see the info from your ECU displayed to you somehow?

 

c) Unless you are tuning the car yourself, find what your tuner is comfortable using and has a good track record with. No point bringing them something they have never used before. It doesn't matter how expensive or "good" your ECU is, the tool is only as good as the person using it.

That is correct, it is possible to run the stock ECU alongside the EMU but that is not ideal as it is quite a lot of wires to deal with.
