Launch control for Motronic

[Simons]

I think, and I hope, that Mr. D is working on it

What do you think Paul?

[Rocco]

and the speed signal from gearbox could be used with Launch control and Motronic??? on 3B cars i am talking

[Simons]

No mate, afaik we need a frecuency signal...and our 3B hasn't got it....now

are you saying that WE CANT USE LC on our cars??

The issue is threefold :

1 - VSS signal needs added to 'spare' input pin on the 3B ECU connector... there are maybe a few possibilities for that
2 - a hardware hack on the 3B ECU would need to translate the VSS signal into something the microcontroller inside ECU can do something with
3 - custom software needs written for 3B micro that will understand the VSS signal... at least enough to ascertain the car is moving or not

I guarantee that its easier to convert a 3B motor with coilpacks, loom adjustments, ECU swap for DI (direct ignition) operation than do all of the above.

AAN, ABY and ADU ecus have hardware and software support for VSS

3B ecu does not

We need to wait

But we have AAN ecu...we have something...we need the signal

with 3B ecu is more difficul but not impossible

Rocco and me have multicoils, and we are happy with the change...next step, remove dizzy and put hall like ABY,AAN,ADU

If you guys have gone to AAN ECU and coilpacks then of course all you need is to add VSS wire to the ECU plug. You know where to look up which pin...

Or I can spell it out for you tomorrow - along with where to find VSS wire on a Coupe that left the factory with 3B engine !!!!!!!

Yes...I don't remember...I think into pin 50...do you know the wire colour??

But I think that the 3B VSS signal, isn't valid to do launch control...we need a frecuency, when I test the blue-white or white-blue to fit the cruise control, the signal was voltaje....I don't know how is the climate or the radio signals...

Thanks!

simons - If you want to do launch control a different way then go ahead, but I am telling you that 3B VSS signal is what you need here. It is indeed pin 50 and you will get it as a blue/white wire that comes to one of the radio connectors. Dont confuse yourself any further by looking at it with a voltmeter - this is an AC signal that comes from the gearbox, via the speedo module.

Hack this blue/white VSS wire into pin 50 on your AAN ecu and you are there - use vagcom to look at the group that reports speed in kph to verify that its working - then you are ready to launch !!!!

Paul, I kinda did that on Simon's car when in Spain and it didn't seem to work...
Maybe I did something wrong, but it still showed 0km/h.

Ok, I will use vagcom to verify VSS

now I can't make any test because I needed remove the turbo...

when I have VSS into pin50, and check with vagcom, I will fit launch's eprom and the party will begin

Hi mate! I forget to check if the signal was good or not, the wire was good attach to Bl/W... when I can check it, I will do it

I need launch!!I tasted it, and now, I need it!!

crazy nutter

[djh]

Are you still looking into anti lag?

When I get my UrS6 together again, then...
