Launch control for Motronic

[prj]

The rs4 maf are well cheap, i know a few have moved the maf to the pressure side is this a good move?
Also can u add anti lagg to the motronic?
cheers nip

I don't see why the MAF should be moved onto the pressure side. No reason to. Especially with a HFM5.

I cold add antilag, but people will melt their turbine and exhaust manifold and then blame me for it.
No thanks.

Global MAF hating is mainly down to the price of the replacement part which quite frankly considering how wide place they are in cars is not understandable.

Yes, but for HFM5 the replacement cost is 60 EUR.

Have you got details of this conversion with the RS4 maf, is coding only or is it bespoke to your tuning only i.e car has to be tuned by yourself

There will not be details of this released. I worked on this for close to half a year.

Have you example car projects working close to these power levels, threads, dyno's etc ?

No dyno yet, but I have a test car with it, and so far everything is fine.

If you want an example of this MAF, you can take some dynos from 2.7 BiT, which will show you that the RS4 MAF works to 600hp.
No different for M2.3.2.

i like motronic, i want to use a tubular exhaust manifold but cant due to maf being so big, i dont wanna go vems , how much is the software and maf. cheers nip

I don't sell pre-made chips for anything except stock and RS2 setup. I never will, because it's stupid, especially with levels above 400hp. The more I can raise awareness about this, the better.
You don't see VEMS users copypasting configs either on 400+ hp cars, because they understand that such behaviour can lead to disastrous consequences.

Why do you want to "get rid of the MAF"?
I already have software that runs with the RS4 MAF, which does not max until 600hp.
All this mass-flow hate is silly and caused by misunderstanding.

Also, it is mostly stated for marketing reasons. Look at ME7 cars. They make 800+ hp on Motronic just fine.

Just had a thought for another location for controls.. In the ashtray, still within reach and can be totally out of sight if the lid is closed.
What do you think?

It is a possibility - if maybe fiddly to get in there... I often thought it a good location for other hidden switches... trouble is lots of folk use that location for trash unt ash

MAF hating is also due to fact that hot-wire version gets destroyed much above 400bhp... hot-film MAF is superior in this regard and I know prj has been working on that - we got some more fun to do with scaling and such for a cleaner install... The principle of a MAF is perfectly sound.

I have just fuel cut.
I don't want to retard ignition, because someone will blow their manifold and melt their turbo with it.
For that to be even remotely safe you need EGT feedback, but Motronic does not have EGT. Of course, it is possible to add EGT to Motronic, but I don't see the need for it just because of this feature...

[quattrofrank]

What settings do you use on the launch?
soft rev limiter with 50% fuel / ignition cut and like -20degress igintion ?

Tried to fiddle around with my car with 60% start ignition cut and a 200rpm range with 90% end cut. Didnt manage more than 0,4-0,5bar.

The only way to get a good launch control setup is to just try different settings, or is it a "recepie" to have a good starting point?

When? so we can get rid of the maf alltogether, is this possible? if so hurry

We all learn every day. Many people would buy it I think just because they can implement changes with help from others....like VEMS.

[QUOTE=prj;558872]Motronic without MAF on MAP sensor coming in summer most likely.
Don't know how well that'll work yet.

I don't think the daughter board is worth it money wise.
I doubt many people will buy it.

The thing is, the ability to tune is just half the problem. The other problem is knowing how to tune, and that doesn't come over night.
Just because you can adjust maps in Motronic or in VEMS does not make you a tuner.
And it will be much easier to let a tuner tune VEMS, since more people are familiar with it and speed density...

[Billman]

Adjustments will be 1800 to 7200 rpm in increments of 36 rpm.
We will be testing it with Paul shortly.

You and Paul should let this launch control thing and get on with the daughter board stuff. That way one can set RPM limits etc. on his own plus it's gonna give you more moneay :-)
