Launch control for Motronic

[prj]

I have 0.7 bar at 4900 rpm with my Stage 1+ s/w.

[S2central.net]

well it spins wheels on dry tarmac with 0.5bar at 4250 ish so its plenty enough !

Here is a vid of the prototype - proof that a few lines of code, some PCB tweaks and a variable resistor can create user programmable launch control on a 20yr old ECU.

This is hooked up thru my breakout box just as the easiest way to demonstrate it.

I didn't attempt to film an actual launch yet - pretty tricky to do that on your own with an iphone.

I am shocked by three things -

1. That this has been done at all - pretty cool and I'm sure a world first - Dmitri unlocked a very nice trick in the code that I was able to augment with a h/w mod... We agreed the way it should work as a sub-system and there it is.

2. The actual launch is impressively fast - spins the wheels (winter tyres) on dry tarmac around 0.5bar on a couple of launches circa 4200rpm. Much more boost would create more spin on the same tyres.

3. That S2 central now has a youtube account... what next - bakebook ?

Video title is wrong.
Should be "look what I can do with me knob".



Anyway, this is getting finalized now, and expect it in an ECU near you soon.
Next is flat foot shifting, but that'll take some time, as the code to do that is much more complex.

OMG - a million hits on youtube already - LOL

cooooooooooooooool

leave it as is and make a serious Launch control

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.

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"!

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.

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

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.

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.

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.

Off topic: I LIKE DINOSAURS LOL
