Launch control for Motronic

[s2_wot]

Funk switch + dash light dimmer switch lads located over the radio?

Great work I feel the need to burst a clutch / gearbox / driveshaft soon. Combined with the FFS this would help the old girl shift fairly well.

Want!

Adjustments will be 1800 to 7200 rpm in increments of 36 rpm.
We will be testing it with Paul shortly.

If I get a chance i'll try this as I have a few stalks laying around

Could you also post measurements from the intermittent switch (min-max value of the rheostat, how many steps and what increments they are at).

[Acidburn]

BTW - have you actually tried to fit B5 stalk onto B3/B4 yet ?

You are on Motronic?

Yep

Now we're talking
The 3rd to 4th shift steals so much time that I'm faster in the 100-200kmh by using 4th only. Flatfoot shifting could change that.

Coming soon - flatfoot shifting

I voted both centre console buttons and diff switch area - keeping it oem looking would be a plus.. maybe the difflock area would keep the centre console looking cleaner. It would be good to incorporate bottons for switchable chipset & valet mode too.

Wiper stalk would be very cool but if other functions are installed you'd still need something else elsewhere.

Not yet, but it looks similiar enough to try, I have fitted C4 A6 stalk to B4, and also one unknown origin Cruise stalk to B4 (possibly B5 but I cant verify it). Basically only thing that needs to be chagned is the stalk on the base, the base itself with the inner end of the original stalk remains. Therefore it does not matter if the source stalk comes from limo or avant.

If electrical side fits for launch control, then i'll fidle with it until I get it fitted
It's on my to do list to find out if the rheostat is up to the task.

it should be below VEMS for sure so much less than the rest ECUs. With a standalone you must program idle and the rest but get away from the limitations of the factory ECU (MAF, no WB control, no EGT failsafes), antilag, lauchcontroll, flatshift in once.

Motronic without MAF on MAP sensor coming in summer most likely.
Don't know how well that'll work yet. Flat foot shift coming soon, WB control is not needed on a system with MAF, because it's MUCH more precise than speed-density.

"We'll be releasing a self-tuning USB programmable ECU mod for the 7a, 3b, adu, aan, PT/ABH, etc."

They said that a year ago, haven't seen anything yet.
It gets brought up every once in a while.

Don't want to hijack and don't know if it's against any forum rules so please forgive me in advance and delete if necessary.

Target price would be perhaps 450 EUR.
Over that and it's not worth it.

[quattrofrank]

Kinda depends on the price, the best aftermarket ecu`s costs about 2000euro`s or more. So I guess it needs to be somewhere between what the cost for the cheapest and the most expensive ones.

Wow, great plans Dmitri. It should have a really simpple software gui, for dummies.

It will never be simple, because Motronic is not simple.
The GUI would be TunerPro.
But with sufficient documentation and knowledge of engines - very possible.

The thing is though, I am not sure if there would be a market for this.
