Hello I was wondering if you can use a ralliart ECU ir the the anti-lag system on a american mitsu eclipse.

 

You should be able to use ALS, but as Claudius said, it's not very good for your turbo. You'd need to run a programmable ECU with that feature, (GEMS, MoTec, Link,...) and you need to get some pressure from somewhere to hold the throttle automatically open when you lift off. On road cars people use the brake pressure, but that can mean that you'll be lacking it when you really need it. I've seen pics of a road car that had a rally style compressor in the boot.

 

as above, the picture is on my website

you may want an up rated fuel pump too!

 

Cheers Ryan, couldn't remember where I saw the pic! But then again, considering the amount of pics you take, 1 out of 10 digital pics in the world will be taken by you

 

I guess I don't quite understand how ALS works and why it would kill the turbo.Could someone elaborate?

Yes I'm getting an AFC,along with my 660cc injectors I can finally go from 9psi to 20psi or if you prefer .7bar to 1.4 finally getting some action out of my new turbo.

Late,

 

ALS works by creating combustion in the exhaust manifold with a closed throttle and this keeps the turbo spinning and generating boost in between gear changes.
It will damage the turbo because of the increase in exhaust gas temperatures caused by the combustion in the manifold and not in the cylinders.

If you're looking at running ALS, you also need to consider that if your car has servo assisted brakes, then these will no longer be assisted because the vacuum for the assistance is taken from the plenum chamber when the throttle is closed. With ALS, you will not have a vacuum when on closed throttle because you will still be generating boost like MichaelK said below.

After all of that, the reality is that ALS is only really useful on rally cars were tenths of seconds saved are important. On a road car there is not really much use for it unless you like really big flames out of your exhaust but you can achieve that on an EVO with other mods....

Thanks for the reply,I now see why ALS would not be of an use on a street car. just trying to see what evo parts I can acutally use on my talon/eclipse.

Late,

 

Hmm, I know of a Evo7 rally car (GSR spec running Anti-lag) without any 'extras' for the braking system. I'm told it works very well. Infact, none of the Evo rally cars I've seen have this extra compressor fitted.

 

The pressure doesn't have to come from the brake system, it can be from a compressor and that doesn't have to be fitted in the boot either. Also, a GSR-Spec rally car?!? Is that with climate control?

 

I thought the pressure/vacuum was needed by the braking system??

Anyhow, none of the rally cars I know, have anything added to the braking system, except some clever tweeks. They all run anti-lag via Motec units.

Im pretty sure I was told their Evo7 rally car was a GSR spec car. So I guess if they havent removed it, they are pretty cool inside!!

 

Tommi,
You only need the vacuum if you're using servo assisted brakes. If you can live without the servo effect then you don't need a vac pump to provide the assistance.
I would have thought that most of the rally teams will run a hydraulic assistance setup on the brakes so the ALS doesn't affect the brake setup and a vac pump isn't needed.
