Okay, I have had Stage 2 on my 07 STi for a little while now. I have also run the launch control map for a short time, but I reflashed back to the regular Stage 2 map because I hear nothing but horrible stuff about how bad the launch control is for the car. My question is that is it safe to run a two step that is speciffically designed to allow me to launch at a decent to high boost level, or are all types of two steps bad for the car. I really love the difference when i launch at 5000rpm with that extra boost out of the hole as opposed to having to blip the throttle prior to launching. My 60' is a ton better with launch control, but I rather not blow my junk up for a good 60. I do have after market motor/tranny mouns and the TIC clunk killer, so my parts dont slam around under harsh launch conditions. If anyone can give me some info, I would be greatful.

I wanna know too! Maybe even COBB & RomRaider specific?

[howboutthemapplz]

youre talking about the FFS?

if so yes i have used it waay more then once, after you flash the base map you must adjust that FFS (flat floor shifting) higher, otherwise there will be a ton of lag, and you will freak out and think something is wrong with your car.

btw i set my launch control to ~5000RPM and my FFS to ~5000-5500 RPM.

I know about the ins and outs of launch control/ffs with the COBB Accessport. I also know that everyone who knows about these cars say that the launch control is very bad for the car, and that it has a lot of potential for doing irreversible harm to the engine. Im asking if all 2 steps are bad for the car, or if there is one that has no adverse effects on the engine. I too have used the launch control option on the COBB, but now I'm basically scared to utillize it, but I still want to be able to launch the shiit out of the car! my 1/4 mile times suffer when I dont use the launch control, but if the choice of lower et's or blown engine is what I get out of using launch control, then I'll have to refrain from using it.

driving the car will shorten the life, does this mean that you wont drive it??

i use LC a lot, but you just cant sit and hold it for like a minute, i try to keep the rev time to a minimum. in short ANY form of LC is hard for it, so is tracking it (auto x or 1/4 mile).

all the LC needs is about 5 seconds of revving to be at its peak boost of ~9 psi or so.

yes LC is not GOOD for the car. tough on motor mounts trans mounts, and a lot of oter unmentioned things. so some will say that its not good to go WOT either.

I know what your saying. But when your on ffs and tour timing drops from knock that's not good. And I know that when I used my lc with the accessport my aem widenand maxed out lean, so how could one think that it is okay at all? Bouncing off any form of revlimit causes knock correction. I don't care if I have to replace my mounts twice or even three times a year, but I don't want to relate my motor.

Btw, my tuner recomended I didnt use it.

LOL, I guess you're right. I have driven all kinds ofo stuff....11sec Cobra, 11 sec SRT4, and a few others....all having 2 steps. I just never had as many people saying not to use it on the other cars. I know that I cant sit at a red light in traffic banging off the revlimiter, waiting to launch the car! I just want to use it at the tack every once in a while. I dont race everywhere I go, but I do tend to go on spirited drives through the twisties near my residence. BUt on those drives, I never use launch control once. Oh well, if anyone else can chime in, I would appreciate the advise on the topic at hand.

well, (not being a d!ck) learn to launch without it...
i will be learning to launch without it next season. my best launch was without launch control on stg 2 setup i hit a 1.75.

i will have a pro tune in the next few weeks, and i will not care for LC or FFS.

as stated before, on a stg 2 Cobb map, i would use it a fair amount, just not for long periods of time.

sure its much healthier to just launch regularly. if you cannot launch this is a great (but potentially costly) advantage.

I never use the ffs. I find that the car shifts great without having to shift at wot. I have tons of bushings all over around and under my tranny/shifter to quicken shift times. The stock turbo is tuny, and doesnt hardly presents lag during my shifts, so I never utilize ffs. As for the launch control, I guess the only alternative to using it would be blipping the throttle until the green drops. But to me, that is the same thing as launch control. If you hold the throttle at 3500 or even 5k, the boost isn't there, and the car has no rpm range to build it up off the line. There has to be some other way to build boost off the line. I just wanted to know if I should look into something other that the COBB launch control, or if it too bad for the engine period. I do go to the track about once or twice a month. When there are events such as this past sunday, i do tend to get a lot of runs in on the strip. Those only happen about two to three times a year at my local track though.

I guess I will have to go out and perfect the launch control-less launch! I dont take it as anyone being a dick, lol! I do need to learn how to drive this car. As I said earlier, I have had all kinds of cars, but this is my first AWD. I love it's ferocity out of the hole, but I love it even more being able to hold the gas to the floor, and having that boost kick me in the a$$ leaving the line! I have a few places that I can go and try it out. I just wish it was like a NA mullet car....line lock and hold down the gas! But still, thanx for the info.

launching without the LC, i usually will blip throttle at second to last yellow, and on the last yellow let up the clutch as soon as the last yellow lights up start slipping clutch. this is gooc for like.01 reaction times.

Thanx for the tips. I just need to go out and try it now.

This is off topic, but you can check out my car in the video section. I think the title is Skunk2 Catback on STi. I just had a **** ton of people asking to hear the Skunk exhaust on the 2.5l.

Thanx again.
