Best way to learn how to launch with a 2600..

[UndergroundR32]

My question is what do you think the easiest and most beneficial way to learn how to launch is, if you're just starting. With or without a 2 step, and what are the reasons for your choice?

the only way to learn IMO is just do it. Just don't dump it, do a fast "ease off".

I'm going to translate that as meaning you shouldn't use the 2 step to assist you.

I don't want to be a dick... but this has been hashed over a BUNCH of times. Slip til it grabs then let the rest out as quick as you can without bogging or what not.

If you just dump it, you'll end up breaking things.

Okay, I don't want to be a dick either, but I don't think either of you are understanding what I mean. Maybe I'm not asking this correctly. I'm pretty sure I don't need to explain what a 2 step/stutterbox mod is, right? Well, let's say I launch by setting my 2 step rev limit to...we'll say 5500 rpm. I'll still slip the clutch, but all I will be doing with the throttle is flooring it since the 2 step will hold it at whatever RPM I want to launch at (in this case 5500).
OR will it be better to learn without the assitance of the 2step/stutterbox mod? By controlling the throttle with my foot, through the whole launch.

Maybe that explains my question better? I know that there are countless threads entitled "How do I launch my AWD?"

Unless ever single launch you will ever do is gonna be with the 2 step then I suggest learning how to do it the old fashion way first, then once you get that down try it with the 2 step.

Thanks for the input

This has me some what worried. If you learn with out the "box" then and only then would you really learn how to control the throttle wich will be beneficial for you in the long run.

P.s A stutter box is best only left to the pro's who use it in conjuction with a dog box wich will let you shift with out depressing the throttle.
See what you dont fully understand is that by being at wot with a stutter box you need to take special precautions.

Yes you will preload you'r transmission but you will still need to slip the clutch wether it's a 2600 or a twin carbon cusco , it doesent matter preload is one aspect but what about sudden friction can and will you'r stock or semi aftermarket shafts take that force?

Ok so you rev till 6000 you slip it but then you limited you'r first gears ratio's to 6000 making you shift early , now we all know different manufacturers make differnet styles to fit what you need, so you said you have a two stage right? So what are you restricting launch then first gear ratio? Im just trying to figuer out how to better help you out.

Oh and the reason I said normal is better is because the way you'r car will respond to different tires and different boost settings will ultimately have you stressin about the "optimal" rev limit. Meaning you will always have to be changing to better fit the moment and current upgrades.

What does a stutterbox have to do with a dogbox or synchro transmission when it comes to launching? I'm not talking about powershifting. Now the way I'm understanding what you're saying is that you mean I can't necessarily leave my foot all the way down on the launch and just worry about my clutch slipping? That I have to vary the throttle even during the 2 step launch?
I don't know what you mean when you say
"Ok so you rev till 6000 you slip it but then you limited you'r first gears ratio's to 6000 making you shift early , now we all know different manufacturers make differnet styles to fit what you need, so you said you have a two stage right?

Why would my rev limit be at 6000 when the clutch is not depressed? The 2 step is activated only when the wire is tripped, which requires the clutch pedal to be pushed down in order to complete the circuit. BTW it's a TMO chip 2 step.

sorry sometime I get ahead of my self and I guess that can become confusing for you and other members. I just thought since you were going to use a launch "rev" limiter you were serious about racing. Why else would you get one ? So I personally thought that if you were to put you'r self in that situation then a dog box would also be a good idea that would benefit you while trying to better you'r time. So As far as stutter box's go, my buddy Jeorge got one installed , but it ended up doing him more damge then good . Like I stated earlier it's better to change and better you'r driving b4 you go and try and better the car.

p.s if you re-read my post carefully then you will understand that some manufacturers can reflash you'r ecu or give you a tunable add on ,but they are all different . My buddy Joerge had his ecu reflashed so his revlimiter in first was set at 6grand ,funny thing was that he would launch fine but he would have to shift to second when it hit 6grand in first BECAUSE the rev limiter was set to limit the revs in first. Get it?

All you have to do is ask bro , not start quoting ppl and wondering why he said this or that. But whatever have fun with your two step.

Even with a 2 step (stutterbox), don't floor the gas pedal waiting for the light to turn green. Yes, you will build a few psi of boost, but when you actually start slipping the clutch, you will most likely do one of 2 things: burn the clutch up real fast, or let it out too quick and roast all the tires or break something.

I think a 2 step is so much easier to launch with, especially if you are actually racing, and not just Test and Tuning. With a 2 step, you don't have to worry about holding your rpm's at a certain range. It does it automatically. I remember racing without one. I would have to rush up to the starting line, rev the car and try to hit the desired rpm. All before the other guy got staged. It sucks looking down at your tach trying to maintain steady rpms, look up and the light is already green. Even if the yellows are just coming down, your timing is gonna be way off. I stage, then wait. I watch the other guys staging lights. As soon as both of his lights are on, I rev the car. Soon as I see the first yellow on my side, I'm counting down. Everything is automatic from then on out. Without the stutterbox, I'm guessing where my RPM's are, not paying attention to the tree, etc.

I'll give you MY launch technique (which has netted me numerous 1.59 60's on Green Dot retreads, stock 158k mile suspension, and a 3000lb car). My stutter box is set to 5000rpm. I push the gas pedal in until I get between 50-60% throttle (this is all while I'm staged). I don't spend much time adjusting throttle position. I can just FEEL where 50-60% is, since I've done it so much. As soon as the light turns green, I start coming off the clutch and giving it gas at the same time. This is the part that is hard to explain. It's just something you need to practice and experiment with. People often ask me "how long do you slip the clutch for?" "When do you go full throttle?" According to my logs, I go from 50% throttle to 100% throttle within .3 seconds of the launch. It all happens very quickly, and it must happen SMOOTHLY.

If you come off the clutch too quick, or wait too long on the gas, at 5000 rpm, you are gonna bog the car. Wait too long to come off the clutch, and you are gonna glaze it. I tried launching at 6k once, using the same technique. Did nothing for me but spin all 4 tires. I'll never run a car seriously without a stutterbox ever again.

Wow, I'm baffled. Why would you think I'm not serious about racing? I just meant that my question didn't have anything to do with using a stutterbox during shifts, but right now my question was concerning the launch.
I am not about to spend a few thousand dollars on a dogbox. I have never even thought to. I have many other mods that I think are more important than that right now.
If you notice in my quoting of you, I WAS asking questions. I don't know why you're making it seem like I'm attacking you

Exactly! That's one of the main reasons I'd like to use one is because it's annoying and time consuming to sit there and try to get your revs at just the right RPM that you want.

Awsome, that helps me understand it quite a bit. I know what you mean and understand what you mean by not being able to explain it. I tried launching once and it was more of an accident but the car just took off. My worry was that I did it too quickly, but from what you're saying I think it may have been just right

First off Undergroundr32 Im sorry if you took my words as a retaliation I guess I just read you'r post wrong, my bad.

Secondly NOSLO2PTO wow bro great post. You are right it is a nusence , but my mentality was If you never tried bettering you'r foot work then you would never appreciate what a stutter box can really do. Well Im glad you posted , And I hope you will be at the shoot out this year. Every day that goes by is another day I look forward to racing with the dsm community.
