I added basic launch control functionality to M2.3.2.

Rev limit below certain speed?

Rev limit below certain speed?

Pretty much.

I am thinking of making it an ignition cut, so it builds more boost.

[andy10v]

Pretty cool.

I take it using an ignition cut would be for short periods (ie launch ) or things would get hot?

[prj]

Yeah, could be done. Things would not get too hot if you don't overdo it.
But I don't think having an ignition cut would be good to have on all the time. Better to use a button to enable and disable the ignition cut.
That's why that is taking longer... you see...

[Dan]

Nice!

Good job

Look forward to hearing how you get on with the ignition cut. It'd be good if that was button activated.

[prj]

Agreed on the button.
Well, this is better than nothing - also, it managed to build 0.2 bar boost on that car, and it's running a k26/k27 hybrid.

You can see the limiter is different with the car moving and not.

[prj]

Just tested it some more on my own car.
The most optimal setting on slightly wet asphalt was 4900 rpm.

It also made 0.6 bar boost on the spot - so I would say it works as antilag as well to an extent.

[prj]

Just to mention - this can be added to any existing setup.
Only one chip needs to be modified and it is possible to keep the current map and only add the launch control.
I have it working and tested on non-immo S2/S4/RS2 and immo S2/S6/RS2.

You are such a nerd!

Can you made it adjustable?

[prj]

You are such a nerd!

Can you made it adjustable?

It is adjustable if you have a chip programmer.
But if you mean from a button or from vag-com. Yes, it would be possible to use an adaptation channel I think...
That's not ready yet though.

[prj]

Found how to make it adjustable using a simple potentiometer.
So you can have a knob you turn and that adjusts the cutout RPM.

Coming soon - flatfoot shifting

Have to say im impressed after market ecu functionality on motronics

I haven't tried these settings on vems yet either, might have to have a play now.

You're on a roll!
