where is....
it revs to 4k or whatever you set your 2-step to, it was made for turbo cars as a misfiring system to build boost to launch, for n/a you dont really need it since you can just launch it without building pressure. but it looks cool

launch control - - - I was doing some reading on the GTRs and the trannys can only hold 15 launches, thats from nissan!! Spend 65K on a car, that thing better launch me to the moon...

the 2 step is used to hold it at a certain RPM to build power before you launch it so that you don't have to balance it at a certain RPM yourself which isn't easy. Its mostly used in turbo cars but plenty of NA cars have them too. Spitting fire is because of the straightpipe exhaust and his tune as an aggressive fuel mixture, the unburt fuel comes out as fire. I really dont see why people are freakin out about a 2 step on an N/A motor.

You guys are getting all confused.
2 step and a missfiring kit are two completely different things.
2 step is used for drag purposes. It's a very convenient mod to have if you're drag racing all the time. You don't want to sit at the drag strip staring down at your rpms for that perfect launch and not have your eyes where you need them more, at the tree (the light signal at the strip).
With a 2 step, you set where you want your rev limiter to be for launching purposes. This is only for convenience so that you don't have to be staring at your tack for every run. If you know where your perfect launch is at, set the 2 step at the rpm of your choice, and floor it at every light. It will not rev higher than what you set it at everytime you rev it in neutral.
A misfiring kit (Anti-lag kit)is also another awesome tool to have (turbo'd car only). This allows for you to stay in boost while changing gears in every gear. It's purpose is to keep you at full boost for the following gear. If you driven turbo'd cars before, you'll know that there's a slight lost in boost going from gear to gear and you'll have to wait for it to spool up again. This costs you TIME at the race tracks.
A misfiring kit throws gas in your exhaust manifold, and the heat of the manifold combusts that gas, which then keeps the turbine spinning. This is why you see fire coming out the exhaust going through gears. BUT, a misfiring kit WILL diminish the life of the turbo faster as your turbo will run at hotter temperatures. (Don't quote me on this, but I believe the average raise in temperature in the turbo with this kit raises it 200 degrees F).

is his car running rich? i thought the only ways to get flames to shoot out were to run a test pipe/straight pipe and to run a little rich, and to get flames out of a 2-step is to tune it to dump fuel or retard the ignition for fireballs?

He's definitely running an exhaust with almost no restrictions, but i dont believe he's running that rich. I remember when i 1st started my swap with only the header on, it was shooting flames out the header downpipe. His motor is highly modded, which is why his has no problem making fireballs. And its tuned. Anyway you look at it, the car is sick.

But since you say this works in neutral, Euro R may I ask where you got the trigger for neutral? Was it just a negative trigger wire or what? That would be sweet if our car has a neutral safety switch so I can tap that to my remote start.

nah i think hes running rich. he seems to have always been running rich.
i know ive been running rich since day one too. and i been told by friends that i pop the occasional flame, but not as frequent as shaun does.
BTW hows life as a 29 year old shaun? i hope to christ thats a typo. lol

it's all in the chip. im using ob1 ecu with neptune program.
The 2 step and rev limiters are on an ignition cut. It cuts the spark instead of the fuel. The sound you hear is the fuel combusting in the exhaust because there is no spark to ignite it in the engine. There is black smoke because its not being ignited in the engine. Its actually less harmful on the engine than a fuel cut rev limiter that most tuning systems use. I am burning rich because im using 440cc injectors with my set up that's why.

He definitely didnt really launch at the tollbooth. No tires screetching or anything. That was just to show the 2 step. When he takes off, he TAKES OFF.
Matt what are you talking about "keeping it quiet"? I went to a shop in newark and saw some serious H22 bubbles. Tiny shop in a tiny street with a big speed secret.

how is it flooding my setup? my compression 11.5 if i used stock injector its not enough fuel cause im maxing out the stock injectors. n plus that why when you do work to the motor you need to tune it so everything is right to get the max power.

You are running rich thats why I have reason to say that ur flooding your setup. Let me see the page of your neptune. It should look something similar to this. This is mine currently. 
Is that 11:5 compression from your Euro-R setup? Just curious?
I do know what the capabilities of a tune are. More fuel requires more air to compensate for the combustion or else you run rich. More air usualy means forced induction not naturaly aspirated.

11:5 compression is from his internal work.
ghetto, if ur grandma's cadillac is doing that, she probably shouldn't be driving it lol. So no, she's not cool.
