Fcon V Pro Vs AEM


GeordieSteve

Recommended Posts

Ok I know I should do my research but I keep hearing niggles about each system.

 

I need an ECU to run on my Supra running a PT71GTS and 1000cc injectors. I'll be installing myself but having it taken somewhere to be set up (I'm oops norf btw). Now Thor recommended AEM but they admit there are some problems. I've also heard Fcon V pro is a good system and TDI North will be able to set one up.

 

Can anyone give me some advice?

 

Thanks:love:

I am not able to comment about the AEM ecu, I have little direct knowledge of it, save that I read they have, or have had, issues with controlling the auto box functions. My favourite would be Motec controlling the engine amd stock ecu the auto box, unless you want to convert to manual shifted auto box, with no electronic or auto shifting? This might simplify things a lot, depends on ultimate goals for the car. Syed Shah has some knowledge of these boxes, I think?

But an AEM with all the additional bits and bobs is over £1500, isn't it? (Going by the one ChiefGrover was selling the other day) so by the time you've had that mapped you're going to be looking at well over £2000, right?

The F-Con Pro V is the daddy of the ecu's with others using it as a bench mark.

 

As Chris said choose the tuner first. Then ask them what they prefer, I take it you have an auto otherwise why not look at the Apexi Power FC.

 

My 'other' car (mine is a Soarer and so is the 'other') came from Japan with an F-CON S fitted, and I was unable to find anyone with the Japanese version if the software to map it. Resulting in the need to get a new ecu.

 

As it is a manual vvti I looked at

 

Apexi Power Commander

Emanage

Emanage Ultimate

F-CON Pro

 

The owner of the car asked his Japanese turner what and who he recamended and the answer was...

 

Abbey Motorsport (as they have a good name in Japan for tuning HKS stuff and Skylines) and a F-CON Pro.

 

So, bearing in mind it had all the loom in it all ready from Japan and the old unit I was somewhat supprised when the bill for over £2.5k for supply and fitting and mapping landed! So was the owner (who lives in Japan, I only look after it for him)!

HKS F Con S

1. What is the HKS F Con S?

It is a fuel and ignition computer which allows a person to change the original amount of fuel to be sprayed into the engine and when the spark is timed to allow the optimum burning of the fuel.

2. Why do you need a HKS F Con S?

It gives the person the flexibility to fine-tune their fuel and ignition for optimum performance for different stages of upgrades/tune. It can also be used to fine-tune a standard car without any modifications done to it up until a moderately to highly tuned car.

It is very rarely that the fuel and ignition is optimized for each car for every weather or climatic condition for different parts of the world.

The end result of a custom fuel and ignition map for ones car is that the cars will produce more power, response/acceleration, the engine will be smoother, less coarse or strained and allow for better fuel economy.

For moderately tuned to highly tuned cars, the F Con S provides the tuner with very precise fuel and ignition control which in turn allows the tuner to fully utilize the engine upgrades that they have installed.

3. What cars can the F Con S be used for?

The F Con S was primarily designed for Japanese sports cars but it can be incorporated into most of the Japanese cars.

4. How is the F Con S incorporated into the car?

The F Con S runs in series with the original Engine Control Unit of the car. A wire harness is used to link the F Con S with the car’s original Engine Control Unit. The F Con S can be easily bypassed to troubleshooting engine related problem by just removing the F Con S wire harness link and connecting back the original wiring to the Engine Control Unit.

5. Can I remove the F Con S and use it for another car?

Yes, in most cases you are able to use the F Con S for another car as long as there are no compatibility problems between the new car’s Engine Control Unit and the F Con S.

6. Will the customers be able to tune the F Con S?

No, as the software is not released to the general public except for HKS authorized shops who are trained in the special setting procedures and have access to a chasis dynamometer and many other support equipment .

HKS F Con V Pro

1. What is the HKS F Con V Pro?

It is a fuel and ignition controller just like the F Con S.

2. What is the difference between the F Con S and the F Con V Pro?

The F Con V Pro has the ability to control the fuel and ignition more precisely than the F Con S as the F Con V Pro has “Higher Resolution” just like comparing the picture resolution of a Video Compact Disc (VCD) versus a Digital Video Disc (DVD).

3. Then why don’t I just buy the F Con V Pro?

Generally you do not really need that type of resolution on a standard or moderately tuned car as the resolution of the F Con S will suffice in most conditions.

But you need that type of resolution for a highly tuned to extremely highly tuned car. For reasons being that by tuning or upgrading the car extensively, it makes the car difficult to drive on the street and for everyday commute. Therefore you need the precision of the

F Con V Pro to give you back the ease of driving of an extensively modified car.

Another reason for using the F Con V Pro is that it allows the car’s original Air Flow Sensor to be removed, therefore providing less restriction of air into the engine thus allowing the tuner to make more power. If the air flow sensor is removed without the F Con V Pro the engine will not function properly as the original computer will not know the amount of air entering the engine thus not being able to calculate the right amount of fuel to be injected. This may cause the Engine Check Light ( Engine trouble code) to appear making 2the car undriveable. Therefore with the F Con V Pro it allows the car to run without the original air flow sensor and yet not show an Engine Check Light (Engine trouble code). It must be noted that this function is only a available on the F Con V Pro, the F Con S does not have this feature. There are many other features that are also available on the F Con V Pro that the F Con S does not provide. Another feature is the ability of the V Pro to change the RPM Redline of the car, allowing the tuner to change the RPM redline up or down any RPM that they wish.

But this is the car that when I met up with Ian C in Norwich one fine day.... and we went for a little drive.... and it is a 1JZGTE vvti with a HKS28/30 single on it.... was heard to say by the passenger in his car......

 

Fek thats quick!!!! :eek: :swear:

 

As it lost him going around the private test track that he uses. And that was with the old Japanese set up ecu. :whistle: :drool:

Don't forget about the cost of flying a Tuner over to sort everything out.

Pffft hardly lost me :nyah: I had to keep lifting down the straight - next time I'll use full boost as well ;)

 

But anyway, that's a fast Soarer that is :thumbs:
