Launch control for Motronic

Dmitri i will need this kind of stuff too...in both cars

No problem

[Rocco]

I think it will be useful for drag sessions... I want to try with/without on a G-meter to try and get some measure of quantifiable benefit. Not too many times though - I like my clutch too much.

Paul,use it only very few times,,only for fun or for run away from the police

Dmitri, do you think that is it a worth upgrade for 1/4 mille sesions??

Of course, because you have 0.5-0.7 bar boost when you start like this.
I have a 3 bar map sensor, so the computer is ~1.2x wrong. But the computer is very inaccurate. The 0.5-0.7 I got from my datalogger.

Killer Video - Very impressive- that said, wouldn't think the clutch would last long with all the G going on! let alone all the engine and gearbox mounts!!!

Hehe, yeah it's not good for it, I agree.
I doubt stuff will break that easily though. As long as the wheels slip, it's not that bad.

No!
It doesn't have electronic throttle and it wouldn't know which gear you are going into.

Could this gear detection be used to rev match on downshift?

I'll have to have a play with this launch control - seems like it could be fun. I created a coarse gear detection map as well as part of FFS idea - that can be tweaked for any gearbox and funky tyre sizes if required. I did it from 1st principles. I want to try the gear detection via OBD to see how reliable it is first of all.

Before I get the flat-foot shifting done I need to do gear detection first.
So assuming you are sequential shifting the ECU will rev-match when doing it flat-foot.

Hmm, I think I need to drive to Estonia and take the whole bunch with all the little addons...

How is that one going to work?

You need a switch under the clutch pedal. If TPS says that you are WOT, the switch is depressed and the vehicle is moving, the ECU cuts fuel.
That way you prevent choking the turbo and when you are done shifting you'll still have boost.
A bypass valve does this too to some extent, but this is much more effective.

Coming soon - flatfoot shifting

How is that one going to work?
