2 step / launch control

[AudiA4_20T]

I think it's kind of incredible that they figured out how to put it in the tune. WTF.

A good step forward for sure. A few years ago it wasn't thought to be possible (only for the EVO/STI guys) but Chris Tapp figured it out first for the VWs using motronic and it seems like JHMs tuner really knows their stuff too because it obviously isn't easy

[beemercer]

How much is the tune again?

$500

^^ Saki, what's the CEL from??

B1S2 (pass-rear) o2 sensor died. Not a big deal, but it was fixed shortly thereafter. Felt like a B5 guy with that CEL

when I got LA added to my tune, I also had 2.5" catless downpipes installed. Within a week of the new dps, one of my o2 sensors gave up. I thought it was maybe an exhaust leak? or something weird...but it was just the o2 sensor.

Little known fact, but when you go with a big change in flow, an o2 sensor can get overwhelmed (especially if they're ~50,000 miles like mine) and crap out.

and you call me a b5 owner, i replaced all 4 of mine when i did my catless millteks and then AGAIN when i did headers. trying to cut costs eh? what are you saving up for that awesome tial 770 kit lol?

[SquiddyB6S4]

that's okay...I don't need you to agree

don't forget, I had piggies for 12 months, then changed 1 thing...piggies to 2.5" catless...and the difference was a serious kick in the back.
Logs show it. GTECH shows it. PBOX shows it.

Hopefully the dragstrip shows it in early May.

I agree. I saw a fairly big difference from trhe change. I really think the more the mods the more the Dp's will effect the difference

Huh, this was not my understanding. I still feel like spending $600 on DP's would be a waste since at some point in my future I'll want headers, but maybe I just need to fabricate a set and do it on the cheap. Not sure I want the increased noise, either, but hey, it's a sports car

yeah, don't do it twice. Do it nice!

piggies make a ton of sense for a stop-gap if you plan on going headers. For me, I plan on 2.5 catless being the end of the DP line so I'm happy where I am.

Even if you do change your mind, don't forget that if you buy used dps, use them for a year or two, then sell them on the used market when you go headers, they'll be basically free. The price of 'barely used' vs. 'well used' stainless steel downpipes isn't that different if you check the classifieds.

WHen i went from piggies to dps i took off .2 in the 1/4. In slightly hotter temps. so the gains are there. But since you are planing on headers i would see if you can find a set on the cheap for the time being. That is if headers are a ways down the road like in my case. I know i want headers but i dont know when ill have the funds for them. And im kinda want to do a engine build and headers at the same time since the engine will be out. So in that case ill be waiting for awhile. So in the mean time i went catless 2.5in and very happy with the performance. The piggie pipes are limited to flow x amount of hp which equates to about 12.5@113 in the 1/4. I went 12.2 after the dps were installed. And when it was colder outside even faster as you are aware of. Hope this helps.

As for the clutch, they can hold up to some abuse if the person launches the car right. I had alot of launches on my stock setup. Alot at the track and alot on the street. My stock setup look good when i pulled it. The only reason why i pulled it was i knew i would need an upgraded one soon enough so i bite the bullet and bought the JHM setup. The stock one was good but after a few hard launches in a row it would start to slip with the added power. That was launch after launch on the track though, never really slipped if id launch it here and there. But when i pulled the stocker there wasnt any heat marks on it so take that with a grain of salt. Also it helps if you know the clutch is slipping and just getting out of it. I think alot of people dont notice it slipping a little bit and stay in it hurting it badly.

exactly. ABORT!

[SquiddyB6S4]

Actually, I think if I was going to do 2.5" downpipes, I'd be building my own. I haven't decided to do it yet, but you're really making me consider it. But the reason I'd build my own is 1) The materials are all of $150 or so, MAYBE $200 if I got a bad deal, including all mandrel-bent stainless piping, flex pipes, and O2 bungs, and 2) I think even the catless DP's on the market now still leave something to be desired in terms of design for performance. If I decide to pull the trigger on this, it will likely be soon, as I get paid bi-weekly, and this month is one of the two months in the year when I get 3 paychecks instead of 2, so me pot 'o gold has a little extra heft to it right now If and when I do, look for a thread started by me with some very particular picture requests.

Cabracco, interesting you say you dropped 0.2 on your ET. I seem to remember watching JHM's time slips and seeing only a 0.05s difference when they went to 2.5 DP's. Perhaps I misread, or perhaps that was with the catted DP's, as I would imagine that catted DP's would indeed be pretty much a useless upgrade. Perhaps I do need to build a custom set of DP's to wring every drop of power out of them

If your going headers. Then ya I would hold off. If you don't want the extra noise then save your time and money. buiding your dps are going to be more then 200$ and its going to be louder and depending on your cat back it can drone quite a bit

As an update, my JHM tune did not come with launch assist (got it late last year). I ordered an updated chip Friday evening around 5pm or 6pm (my time). Got it today at lunch time.They charged me $20 and the deed was done, I just need to go pop the ECM open and install it when I get a few minutes. For reference, yes, that chip came almost 3,000 miles over the weekend.Customer service continues to surprise, even when I already know it's great

Disclaimer: Do not open your ECM if you're not comfortable with electronics. It would be an expensive and generally stupid mistake to do this yourself and pop something in there with the static charge from your hands if you didn't do it right.

HEY there you go good advice. this is something antone can do but you need to take your time. where is the video dam it

[beemercer]

yeah the videos are a big help, bottom of this page

I will have my tune with LA coming this weekend. GF got my an early birthday present

she have a sister. Im looking at the JHM supercharger kit and thinking that a good strong 6months of dating will put us at X-mas. that would be a good gift.

lol. she has a 15 year old brother; I think he is gay so it could work.

[LMFAO JDM]

WHAT the hell i have been asking them for like a month and they have just been kinda putting me off and now you are getting it im kinda pissed.

[B6JoeS4]

Odd. Just took a few emails for me. Just order the tune and then in the addition comments box on their website, note that you want the LA. Then call them to make sure you're getting it

[SeKKeY]

guessing the LA isnt out for B7's yet..?

[Justincredible]

WHAT the hell i have been asking them for like a month and they have just been kinda putting me off and now you are getting it im kinda pissed.

If your a B7 that isn't the same thing as the B6. I know those are not all done.

[B6JoeS4]

He is 05.5 so I think it might work. Wouldn't surprise me is 05.5 is the same as a b7 being as they share so many other things with the b6

[beemercer]

Some of the 05.5's have completely different ECUs iirc, or possibly that was the 25th Anniversery ones

[mbgt72]

^Yea iirc, the 25th ann. ones are pretty different. Crazy to me, but they are apparently.

He is 05.5 so I think it might work. Wouldn't surprise me is 05.5 is the same as a b7 being as they share so many other things with the b6

05.5 = B7 as far as tuning goes as well, so the ECU's are different from the B6 (they're may be some early ones that are more similar, or maybe different generations of the stock tune as the car progressed, but my 05.5 was pretty different from the B6 from what I'm told).

The LA is setup to work on B7's (i.e saki had it first, and I had it after him as far as B7's go I think), BUT it is a lot more complicated. I don't know about Saki, but they had my ecu fro about a 4-5 weekdays before they shipped it back to me. I was in contact with them and the tuner, and it wasn't just them not getting to it, it's just more complicated. The tuner's goal has been to design a more universal code to be applied to both, and after mine, he had been working towards this. So it's possible that the B7 guys may just have to wait for a while as that is developed and let the B6 holligans have their fun.

[DuncanC]

I have it on my B7 so I think it just depends on which ECU revision you have. Even B6 to B6 or B7 to B7 they aren't all the same ECU code from what I understand.
