Btw, I am working on a properly configurable anti-lag system...
Made 1.5 bar when stationary then I let off the throttle

Sounds exciting, requires responsible use?

[prj]

I am making the following things adjustable in software:
* RPM
* Ignition retard amount
* TPS % > X
* Time limit

But even then, cars without decat can not use this - it will instamelt your cats...
On other cars if you overdo it, you will crack your exhaust manifold and melt your turbine.

I am mainly doing it "because I can"

Sounds exciting!

I tried a beta version yesterday.
It works but I need to re-align the code, so it cuts faster. Now it is a very slow and imprecise cut, and it cuts too many cylinders at once.

So at 2000 rpm it makes 1.5 bar, but at 5000 rpm only 0.9 bar.
It shoots lots of flames out of the exhaust though.

When I realign the code a bit for faster cut, it should work in the entire revrange, but that will need to wait for two weeks...
Too many cars to tune right now.

Can i use this with your mapping?

[prj]

Yes, but it is good on your car without
I don't think you need it.

I belive this is the most wanted feature.

You do mean launch control to get off the lights without thinking about the take off? If so I stick to my original statement. No bad... Driving is thinking and should be complex otherwise we may as well take the no thinking route and get on a b... b... bus...

Following that logic, I assume you will be selling your quattro as that does the thinking for you with regards to traction and the ABS system handles braking for you?

I also assume you don't have an oil pump but have a series of hand pumps in the way they used to do it in the 'good ole days' - more of a challenge to think about the lubrication as your driving. Also you don't have a sat nav as that takes the thinking out of getting lost?

I for one am planning to add launch control, will be keeping the 4wd and ABS and will have much more fun exploiting all of them as much as possible :mischeif:

I take it you will have removed the ABS from your car for the same reason
Come to think of it, going by your statement, why do you drive a quattro, you should weld the centre diff up and remove the front drive shafts.
you seem to be much better suited to BMW forum.
The main point here is that if you don't want it you don't have to have it,
slagging this off just makes you look stupid.

D'oh ! beat me to it.

Uhm, you will not build 0.7 bar of boost at standstill without launch control.
With ignition based cut you can even build 1.5+ bar.

Basically no - you can not do this with your right foot and it will make the car go faster/launch better regardless of driver skill.
I explained that already once.
