Lancer evos do spit flames very easily.The ECU is set up to run very rich to keep engine temps down and there is also a BOV that activates after 3 seconds on flooring it.Combine this with an aftermarket airfliter and exhaust minus the Cat and you get flame outs.

 

Misfiring System
(this isn't the exact explaination because i can't remember the whole thing...but the idea is right)

Misfiring system is a system that's in the computer...when you decelerates, it tells the computer to send in large amount of fuel into the engine...but because you are decelerating those fuel are not ignited...and because of the high heat in the engine the fuel turn to vapor form and when you try to accelerate again the engine already has a lot of fuel to burn so it can accelerate fast in low speed like normal aspirated cars...the "bang bang" or "pop pop" sound that it makes was created because the fuel that was sent to the engine when u decelerate turned into vapor and the product of the reaction (igniting vapor gas) is fire and explosion and the only way out for the explosion is the exhaust and so there are fire coming out and u here the "bang bang"

 

Ah, ok, I see; that makes sense, sort of. I always thought the result of running rich at throttle liftoff was the engine stumbling when you shifted, which the DSM guys coplain about when they install BOV's that vent. I guess if they control it closely wih the computer they can get it just right though.

 

mark, anymore of pics like these?

 

Check the links section of the site. There's a site called Evolution V which has a ton of pictures.

diu, finally someone answered my question =D

i posted something bout the misfiring system. Cuz i heard the Lancer sound from the website and i heard misfiring system and the turbo (Initial D is the best =D) and i always wanted to know if lancer really do have it,

 

hell yea is the best

 

It seems the proper name for a misfiring system is ALS, anti lag system. Searching with that, I found several good links that explained it:

http://www.worldrallying.com/if_tek_antilag.php

http://www.rallycars.com/Cars/bangbang.html

As cool as it is, it seems there's no real way to do anything like it on a street-legal car, since it requires a race exhaust, and also possibly a special turbo that can take the added heat.

 

i wonder how come track race cars don't use them...those companies got the money, i see in le mans the turbo cars coming from pit having a hard time and the car just stopped coz of turbo lag...

i guess because since le mans is a 24 hours race....maybe easy to overheat?

 

I suspect with the way in which the LeMans cars are driven, it wouldn't be worth the extra stress and heat to the drivetrain for the little bit it could possibly help. Unlike rallying, where lots of time is spent in lower gears, and there's lots of shifting, but I'm guessing the main reason is the drivetrain stuff. The way this is described, it seems that it would be pretty destructive to the turbo and exhaust at least.

 

Another feature that the aftermarket ECU's give is launch control. You can select a 'software' rev limit. Floor the accelerator and the ECU keeps the revs at the software rev limit as opposed to the normal limit. The ECU also starts the anti-lag up, giving you full boost whilst stationary. When you drop the clutch you take off with full boost, ie a lot quicker than normal. Suprisingly clutches dont last long!

 

but now cornering is alot more important in Le Mans now, u can't just win by beating everyone on the Mulsanne Straight like back then when the LMP900 were new and the GT-1 or LMGTP were dominating
