Launch control for Motronic

This is not DIY... but yes you can be 1st if you wish

[Jonas_R]

So how do you become one of the first 10?

I would like a kit or perhaps a diy kit?

[S2central.net]

Yes - this isn't just a case of wiring up any old pot to an unused ECU pin... There are some internal mods required on the ECU to make the unused input active and to get the voltage levels correctly balanced for operation across the revs - with boundaries that we have in the code to behave correctly if the pot is unplugged and when a clutch switch is detected in the future.

I intend to offer the Variable Launch Control (VLC) as an upgrade to any 20VT ECU that includes the internal mods with a nicely connectorised loom that can be user installed for the pot location.... this will also be plug and play forwards compatible for features with the clutch switch to come in the future.

In a week or so I should have photos and such of the completed installation on my car - I will try to accomodate a miniature version that can be used in either a spare console switch, near the handbrake or the column cover... but I have to balance that with a desire for tidy cabling as well. There is a good chance I can package it with a default location on a short cable that will allow folk to simply extend with an off the shelf cable of some sort to less popular locations.

The cabling will be compatible with LHD and RHD vehicles.

Pricing for this 'must have' accessory is going to be GBP90, but there is a special offer for the 1st ten kits with a reduced price of GBP75

PS - This has not yet been tested on 3B/RR machines yet - it will take a code revision and perhaps a different h/w tweak on the ECU - but I'll hold the same introductory price for 1st ten 3B/RR versions as well.

Finally - the obligatory disclaimer... use of launch control or any driver techniques to create an aggressive transition from stationary to moving has the potential to shorten lifespan of the vehicles engine, clutch, drivetrain and tyres. The VLC module needs to be setup for the car such that some controlled amount of wheelspin is generated on launch - if there is insufficient wheel spin, the drivetrain takes more stress. All things being equal on the car - wet surfaces will need less rpm and drag strip slicks will need more rpm. Have fun - but use responsibly...

On topic: Sounds like this is coming along well. What would I actually have to send to Paul to have this installed? Just a chip from the ECU? Assuming I install the rheostat myself.

Well, if you can manage to do fine soldering, then in theory you only need to send your current fuel chip.
If you can manage soldering and have a chip writer, then all you need to do is send your current binary and the launch control will be added in, then you can write the binary back.

If however, none of those things seem very appealing to you, then you'd have to send the ECU.
Also, the rheostat and the resistance on the circuit is fairly precisely calibrated. Just any rheostat won't do.

Off topic: I LIKE DINOSAURS LOL

Paul are you really asking that question? I found his answer very polite and choose these words to express my gratitude!

I simply can't stand his arrogance.

And for the sake of history a have a big thesaurus, I can use more of them if you continue to answer that way when people comment on something that you don't like.

The only reason you are commenting in this thread is for the sake of arguing.
You do not have anything useful to say whatsoever. And when your arguing fails, you resort to insults.

Until you have something to contribute, do me a favor and don't post anymore useless dribble. Thank you.

Now please let's get back to launch control on Motronic and it's development.

Why so disrespectful billman?

On-topic:
Will try to do something like this for 3B as well.
Have a friend with an Audi 200 who might be willing to test for me.

for a retard like you ......yes!

There is something called failsafes like EGT monitoring. "If EGT is above X degrees then disable" you moron.

An anti-lag system (ALS) is a system used on turbocharged engines to minimize turbo lag between gear changes.

The other is two step Antilag/launch control.

Sorry folks but his arguments ( :corey: ) are very "mature"!

No comment, but quoted, in case you decide to change your statement in the future, for the sake of history.

[S2central.net]

Why so disrespectful billman? Antilag can be added later and yes I have already been thinking about egt feedback or shutdown for safety. Let's try to stay on topic folks.

[Billman]

Do you really think it is hard to retard or cut ignition? :corey:
And that's called antilag btw, also it doesn't have the best effect on turbo or manifold.

leave it as is and make a serious Launch control
