The beginning of the Automatic Launch Assist

B6/7 S4/RS4
#1

So for a while the RS4 and S4’s with a manual car have gotten a big upper hand from Launch Assist (LA)

In most cases almost every company ignores the Automatic guys. Well if you have a Automatic car then you don’t want to be ignored.

Here is some video of the Tq converter being stalled a bit higher then stock and then the shifts that follow on the new JHM tune. Keep in mind this is my car with a JHM supercharger on it. So not all acceleration in the automatic cars will be like this. The hard shifts and what looks to be a stutter is the throttle body closing during shifts to keep the boost in check.

This is the first of many new attempts to get the LA program going for the Automatic guys.

Lets start with how a stock S4 launches and the RPM you can take it to.

Damn. . . that thing MOVES! Can we do an auto swap for my car now?

Is the ESP light different on the B6 & B7? Looks different then mine, never knew that.

Also. . . you just used two words very close to each other that got me very excited. . . Launch Assist & supercharged. I wanna see (and feel hehe) some of the LA on the manual supercharged cars, I think that’s gonna be a blast! Especially since you know most all of them are on stg 3/4 clutches, so you might be able to make it a little more aggressive, I’m getting jealous of you flirting with 1.7 60’s in the autos!

Great work though and glad to see some new videos. Those shifts do look killer though, and I can’t wait for some other guys to experience that in their own cars. Launching is one of the most fun things you can do in an AWD car, and it absolutely SHOCKS most people when they’ve never experienced an AWD launch before.

ya wow that was fucken crazy fast.

#4

Ok, the other videos were good. However… I want this! Thank you for posting it up ;D

#5

HAHA! Freaking awesome man. 1.7 60 ft is neck breaking for an auto transmission. Super cool man keep it up.

#6

Thats just fkn sick. Its a good thing you can’t ware a video out watching it. Ive watched that several times. I can’t get enoiugh

#7

Wow that is great…

How does the LA work mechanically on an autobot. I know you mentioned stalling the TC, does that mean not letting it cut in at that RPM range when you are launching it.

I just received the updated JHM ECU tune and I have to say it’s impressive. The shifts are a lot quicker, and also smoother when cruising. Unfortunately I live in the city and last night there was a lot of traffic and police out for the weekly fireworks show so I wasn’t able to get an updated video up as soon as I wanted.

When I find some time, and some open road I’ll update with what the ECU tune can do. Although this time I’ll bring a fully charged camera. Although suprisingly it’s a lot easier to drive in traffic, yet get’s very angry whenever you feel the need. I only wish I had to drive farther for work ;D

#9

Do want!! Can it be added to an existing JHM tune?

#10

yes

Nice. Let us know when you get a chance to stretch the legs on your car

Awesome! Thanks!

#12

:o

very impressed well done. Its great to see this happen for the automatic guys

#13

Soo, large dent in my car door later… >:( (neighbor). One partially dead flip, a sony camcorder, 4 different executables and I now have the file uploaded. I really hate .mts files, but I do love driving ;D

God! My flash showed up as a white box!!! A link will have to suffice.

#14

The link works great. Nice video. Over stock how much more agressive would you say the launch is.

I know we can’t expect much we are still at the limits of the converter but I looks like the car is moving out more from a dead stop then stock right?

#15

I would say about a 5. It isn’t crazy but it is definitely a lot better. When it was stock it felt a little sleepy getting off the line. It is really smooth and the power comes in right away so you pretty much just go.

It isn’t the crazy launches like the manual guys, but I think that is mostly due to the launch rpms at the moment. Considering this is just the ECU tune it’s a huge improvement because that extra 7-800 rpm is big and it is really consistent. The biggest overall change is the shifts because it is pretty damn quick.

It’s funny as I live and work in the city and deal with a lot of traffic, but the car is a lot easier to drive than stock for normal driving. Then as soon as you hit the gas it just goes. I really want to see what the TCU tune could do because just the ECU tune was really impressive.

#16

OMFG this is exciting.

Good too see all this hard work and development paying off :slight_smile:

#17

wait…

Good bump BlueRocket…I missed this entire thread.
Help a non Tip guy understand here.

  1. the JHM ECU tune now is adjusting tip transmission stuff?
  2. is there also a TCU tune of sorts to go with it? But GameBreaker just has the ECU tune with updates for tip cars?
  3. if someone is JHM tuned with a tip car already, can they update their tune to this new version somehow?
  4. is there a price available for the TCU tune?
#18

There’s a Separate tcu tune which a couple of us have. lts going to retail at $450

#19

B6/7 S4?

#20

B6 3.0, Im sure that there will be one for the S4 soon if not already. It is great to see them test it on the S/C cars first (if it works on that it will be fine on anything else)

JHM TCU tune seems to be the most successful one that has ever come out. GIAC did one for a while, but they didnt keep at it and died off
