2 step / launch control

[LMFAO JDM]

Ok I am interested in a 2 step for my 2005.5 b7 s4. I know JHM makes one they are not telling anyone about but i dont want to send my ecu out there and wait 1 week to drive me car. I was looking into the WOT BOX but they say it will not work on the b7/b6 but it will work on the b5s and like mustangs. Anyone know of anything else that i could get. Thanks

[beemercer]

ask duud40, and better get a stronger clutch as well

[B6JoeS4]

x2 on the clutch. what would be the point of a 2-step on a n/a car???

[tosh2.7]

fast feet and a good driver


p.s. he just did jhm stage 4 clutch

Then your doomed to failure.. Even if you can wire up the mess of a two step your going to need to get past the TQ limmits in the ECU. In my opinion don't go 1/2 a$$ed. Send the ECU to JHM.

IT dosn't take a week and your going to spend the same amount of money and time getting somethign sub standard to work anyway till the ECU shuts you down...

Very well put.

[LMFAO JDM]

Well not trying to sound like a dick but ground shipping from ny to cali is like 5 days there and 5 days back and they make me pay for the shipping even if I got 3 day air that is still like 50 dollars each way and 6 days is close to a week. I mean unless you are willing to pay for next day air. But I do have the JHM stage 4 clutch and lw flywheel, JHM intake manifold, JHM lw crank pulley, JHM 93 tune and a lot more goodies. But JHM was my last resort I wanted to see if there is anything else out there. Im trying to get away from them a little sense they have us ALL tied around the NUTS and on a short rope. Dont get me wrong what they have is great but some one has to try and give Jhm some composition here. Or at least JHM should come to the east coast and do some beta testing on my lol. (I mean if JHM is listening I have to problem testing out your stuff lol you could send me a ram air or oil cooler delete thing that would be great lol)

RAPE sti's and evos off the line and in that case anything just holds it and you just have to dump the clutch and you get AWSOME NESS lol. But I think it would also be cool to shoot flames kinda a dream of mine.

I shipped my ECU overnight from fort lee nj and back. cost about 50 bucks round trip and I had the ecu back 48 hours after I mailed it. so either just do it or stop exaggerating prices

well said

let's let him instead get a wotbox. He wouldn't want this for free would he?

[LMFAO JDM]

What do you have done to that?

[koolade9]

RAPE sti's and evos off the line.

evo's can pull 1.6 60's all day. pipe dream will remain in the pipe...

Well sorry there "captain awesome" but thats what UPS quoted me at.

[jfunkey]

Bro you already have the JHM tune? you don't need to send out your ECU. just e mail them. Thats why you have a chipped ECu they can just mail you the new program you don't need to have any dowm time.. or I missunderstood...I know Im not in NY but I agree with whartung UPS is giving you crap. If you do need to ship your ECU to JHM have them get the shipping quote for you. They probably ship more packages in one day then you ship all year so there prices are going to be better then what you would get

I think at this point they do need the ECU to do the LA rather then just send an updated chip. And the B7's are still a bit more complex then the B6's. Things could have changed or been re-written as more universal code, but I had to send them my ECU for a couple of days for them to write the LA file for me.

But again, this isn't a released product, so they're not even advertising it or at the release state. And I'm not sure if they're really installing it on more people's car or anything. I also wouldn't be surprised if they might charge a slight premium over the "stock" tune when/if it comes out. Honestly, given the amount of time and effort put into writing the code and all for the LA, I think they should charge a hundred bucks or so for the LA on top of the normal tune. We'll just have to wait and see though.

[beemercer]

When I got my tune back in July 09, I sent it out from Worcester Mass late Monday afternoon and had it back Wednesday morning, total downtime for the car wasn't even 48 hours.

I came from an Sti to a B6 less than a month ago...I cant see this car ever coming out of the whole like a well rounded turbo application. Plus the main benefit for LC was to build boost off the line, I cant see a real reason to have it on our cars unless you just want the "bling factor" which is fine haha.

And I would still feather the clutch out, dumping with LC is going to create just as much drive line shock as dumping without it.

No and NO...

[Cards232323]

^^From my experiece in the subaru world I would say yes, maybe this platform is different then, my mistake.

[Silver B6 S4]

I owned 2 STI's (05 and 07) both were stage 2 pro-tuned with LC. Never would I feather the clutch, as that would result in that horrid smell.


This platform is different for sure, and I have to admit that I miss those cars. The writer of this tune is a pure genius.

[Cards232323]

^^Well if your were smelling you clutch you were probably feather ing it for too long, the ONLY reason I would say feather is because all launch control is really doing is regulating rmps and building exhaust gas without you actually having to play with the throttle. So theoretically dumping the clutch at 4k with your right foot holding it there or with LC holding it there would still be dumping the clutch and creating a bit a shock on the tranny.

But I dont want to get too off topic, I havent gotten my chip yet ( only have the car a month) but Im kind of interested in how the LC works on these cars anyway.

That's where JHM's LA (Launch Assist, not LC) is different from every other LC system out there that I've seen. It's more then just holding RPM's and letting you dump it. With their system it's key that you very quickly come off of the clutch. The best driver's are still gonna be able to cut better 60' times, b/c just that, their the best drivers. Vs a LA that's designed to be applicable in a wide range of conditions and power (think about all the different surface conditions, tire conditions, temperatures, power ranges, clutch health/strength etc. We're not talking about the new LC in a 458 that is able to compute those factors to slightly adjust every time for a better launch), but the goal of JHM's system is to be able to create repeatable good launches. Their goal was also to create a LA that would be "safe" on a stock clutch and allow repeated use. My feelings are it's probably easier on the clutch then most people trying to launch on their own (esp when "learning" to launch) as you know what RPM it's engaging at every time and you don't have people get caught up in the moment and feather the clutch and not let it engage till near 4k (as often people will do). And with their design, even if the LA is installed, it still will allow you to launch the car the old fashioned way, so someone like cabracco could play around with it when he wanted, but still go throw out nasty 60' times at the track when he wanted to show what the car and a BA driver can really do!

Again, they're still working to decide if this will even come to the market, and they want to test it on a lot more before they open it up and then have people complained their clutch is trashed b/c they did a bunch a launches (doh. . . ). They let me have it installed b/c I had already ordered the Stg IV clutch and didn't care what happened to my oem clutch so I was a great candidate to see how it would do and what the aftermath would be (and they would get to see it first hand as well as my history as a customer with them). As of right now I do not have it on my car due to the complexity of the system and them not wanting to add it into my tune with everything else going on (for now only I hope). And there really isn't much point of me having it with a new clutch anyhow, but now that I'm mostly broken in, I'm starting to work on learning to launch the good ole old fashioned way again.

[SquiddyB6S4]

Yes. This is the purpose of launch control/assist. It's not necessarily the fastest way to get moving, but you're a lot less likely to F up when all you have to do is drop the clutch at the appropriate time. Also excellent for bracket racing, if you're into that sort of thing.

Absolutly jason. COuldn't have said it better

Well, so much for the "gentlemen's" S4....LMAO

When did you get a clutch and catless downpipes?

[Silver B6 S4]

Saki is still on the stock clutch.

[cam]

Hmmm. Has jhm released the launch assist yet? I know they have been working on it for some time.

[sakimano]

they haven't come out and said it, but a local guy was offered it with his tune (maybe because he mentioned my car or something?) I think if you contact them they'll update you. If you do it soon, they may not charge you?

[sakimano]

hahaha

still stock clutch/flywheel as silversauce said

catless downpipes (Good ear!) - December 2010, which is when JHM asked if they could send me a 'Launch Assist' file to try out (both installed by VAST).

I'd say it works pretty damn well.

pre Launch Assist
gtech pro RR - my 60' times were always about 1.95-2.0 seconds on local roads etc. Best was 1.94. (out of about 30 street launches)
at the dragstrip - my 60' times were always 1.91-1.95. Best was 1.87. (out of about 25 timeslips only had two 1.87 and a 1.89)

post Launch Assist
gtech pro RR - 60' times always 1.88-1.92 for about 10 launches. Tested on my pBox and got the same results.
dragstrip - to be continued (track opens in April)

It's not 'optimized' for the strip or anything. Every track is different. It is however going to ensure that you NEVER screw up a launch. It's like a nice safety net and might help those who can't nail the quick 60' times get something decent. I guess they're still updating/perfecting. Not sure. They'll probably go public soon. I sent them a bunch of videos...

[B6JoeS4]

I sent them a bunch of videos...

lets get some of those videos on here

[cam]

Saki, you have pm

[sakimano]

lets get some of those videos on here

I just posted one!

I'll leave it to them.

[B6JoeS4]

i know but i have a feeling there are better ones [ninja]

I disagree here, with the right driver you can get this car to launch hard. Ive cut a few 1.6 60ft times on heavy wheels non drag radial tires. No slicks either, just your everyday tire.

[UnstableOS]

Hmmm. Has jhm released the launch assist yet? I know they have been working on it for some time.

Yes, my tune with LA will be arriving Friday.

[B6JoeS4]

what was the premium to get the LA?

[sakimano]

what was the premium to get the LA?

you will be shocked

[B6JoeS4]

you will be shocked

yeah he told me 784 shillings extra. not bad

[SquiddyB6S4]

I'm thinking this is now a mandatory addition when I eventually place the order for a clutch/flywheel package, when my stocker finally starts dying.

[sakimano]

hmm...closer to 783 shillings than 784. Closer to 5 shillings too.
