Software controlled Freestanding Rev Limit / "Launch Control"

BPMSport · 09-17-2012, 07:38 PM

A few people have been inquiring about the freestanding rev-limit change / "Launch Control/Assist" feature I offer with my performance software.

Background: This applies mainly to 6MT cars as DCT cars have 'real' launch control built in.

What it does: This changes the rev limiter while the car is not in motion. That means once you hit one mph, the full rev limit becomes immediately available. This allows you to hold a specific predefined launch RPM without any effort.

Why do I want this: For 6MT users, it makes it a hell of a lot easier to launch the car. You can keep the gas completely pegged with the clutch in, and it will rev to the desired value you have asked me to program your file with.

When you're ready to launch, simply release the clutch and modulate the throttle from there. Most people have me set theirs at 3000, 3500, or 4000. The stock freestanding rev limit is 7000 RPM. Counter-steering might be recommended

I took a quick video of it about 15 minutes ago and was surprised at how easy and efficient it is versus trying to modulate the throttle yourself for the initial launch. The car just hooked up and took off like a rocket.

I chose to do it with DSC off, works perfectly fine with MDM or Euro MDM as well.

Sorry for the bad video, next time I'll have a passenger and will post a better illustration of this feature. But for now it will at least give you the idea:

6MT guys are gonna love this!

Where was this when I was 6Mt ...

Nice !

ilya335 · 09-17-2012, 08:50 PM

That is an awesome feature!

mkPOTO · 09-17-2012, 08:51 PM

Wow great feature

Merlosso · 09-17-2012, 09:05 PM

That's awesome.

schnell325 · 09-17-2012, 09:08 PM

Had this feature with my N/A AA tune. Loved it.

VCP · 09-17-2012, 09:10 PM

works really well tried it on a active autowerke tuned car couple years ago. cool that your offering the same feature now

BarryDaviso · 09-17-2012, 09:54 PM

That is an awesome feature!

M3sicko · 09-17-2012, 10:20 PM

This is an awesome feature finally for us the 6TM guys, can't be happier with my 6MT.

BPMSport · 09-17-2012, 11:05 PM

That's cool that Active used to do that.

I've been doing it for a long time for those that request it, but never actually tried it myself until I tuned the car on the latest software version. Thought to myself, why not give it a try.

Once I saw how effective and useful it was, I decided to make it yet another 'perk' of the performance software. I don't think I've launched the car this well in four and a half years of ownership! I definitely recommend it to anyone that has a 6MT car. And for DCT cars, you can stop people from reving to 7K with no load on the engine by restricting the redline also.

M3PO · 09-18-2012, 04:00 PM

The diff bolts are gonna hate this lol!

How am I gonna look cool for my homies if I can only rev to 3k?

In all seriousness, this is an awesome feature!

If you roll 1mph, you can then rev to redline

Thanks - much appreciated!

It's also a pretty sneaky way to get out of an exhaust ticket since they check by revving in neutral

What tune is this part of?

Where can I get it?

How much?

This can be incorporated into our tunes. You purchase directly from BPMsport.

Mike would have to see if he can somehow work this in conjunction with your already loaded Dinan tune.

Jaypod · 09-18-2012, 05:11 PM

I also had this as part of the AA tune on my previous M3. Meh, neat I guess but wouldn't go out of my way for it

This is not a problem. I can either amend the DINAN file, or flash over it with a BPM tune. Either way will do the trick.

Sales@Evolve · 09-18-2012, 05:51 PM

Cool feature which has been available for a long time but strangely no one talks about it too much!

Well done Mike for reminding us tuners to offer it as an option!

Just take care of those clutches boys!

pbonsalb · 09-18-2012, 07:15 PM

And diffs and subframes. At least one expert has noted that failures of those parts on the E46M3 with SMG and launch control are more common than on 6MT cars without it.

Sure would be a lot of fun, though.
