Hi guys....

During my navigation on this forum, i can see that in england, used a lot the air injcetors system for boost control....

It's a very interesting system....but how does it function?! It's very strange for me.....can you help me?!

Cheers.

Cris

 

First of all, you can't use this system without changing your eprom!
Air injectors work exactly opposite to the normal function of boost control.
If the injector is closed there's no pressure to the waste gate and the turbo is allowed to make as much boost as possible.
If you want to decrease the boost you open the air injector a bit and apply some boost to the waste gate, thereby opening it.
So, the higher the duty cycle on the air injector, the lower the boost is.
Normal boost control is the higher the duty cycle, the higher the boost is.

The advantage is that less air is blown off than with normal boost control.
For motorsports applications (with restrictors) this is very nice to have.
On an unrestricted turbo the gains are very small (if there's a gain).

 

Perfect.....

So, i must to install an a remapable ECU like Pectel, Mek Tronic or MoTeC.....

 

No MSD can do this on L8

 

Criscsw, where do you want to use it for? Rally group A with restrictor or road use without restrictor? Any tuners in Italy that can remap the standard Weber-Marelli ecu's?

 

cris want to use on road use


ciao cris

in italy the air injectors dont know how they are...


what ecu can we use to do it?

 

Hi Ludo....

Guys, Ludo is one of my best friend!!!

I want to know bettere this system for a road installation/use with a TD05HL.....

In Italy only some tuners, can remap the IAW 48P8....but in the future i'll install probably a Mec Tronik MTE2......can i use the air injectors with Mec Tronik?!

 

What's an MSD?!? I don't know it..... sorry....

 

Motorsport developments m8,im gonna run air to air on my new engine.

 

thank you cris!!!



it is a develop of p8 or another thing??


in italy we are in the 8th century about cosworth
(and not only about cosworth...........)

 

So....with only L8 and Motorsport Development, i can run air injectors?!?

WOW!!! That's awesome!!

 

No but they can do it.

 

Perfect!!

Ooohh....England.....i'm loving this country!!!

In Italy with P8, the tuners can run onlu ALS....not double map, or 8 injectors, Launch or else.....

 

Marooona,quanti Italiani in giro sull forum

 

aahahahahhaahaha

 

Ludo,beato a te che puoi girare con una cosworth.
Qui a Roma l'assicurazione ti stacca le palle,non parliamone poi dell bollo...

i see all this link this afternoon, it's wonderful how do you work in uk
in italy we don t have nothing like this....

 

Very compliments for Motorsport Developments.....in Italy this kind of tune, we can only dream.....

It's very interesting, that in UK with a simple L8 or P8, you can do all these things......

 

The injectors used are used for air control but are in fact CNG injectors developed for Compressed Natural Gas.
The std amal valve is totally capable of boost control also.
A lot of things done on cars are done for either bling reasons or because someone else has done it.

or because you don t know the best way to reach your goal.....
