Turbolag from hell - launch control!

[Carfreak]

Hi everyone! After 3hours of night fun with my car and a slipping clutch I need some advice.

When launching at about 6000rpm I have 0bar of boost I don´t know if it´s the tune or to little backpressure or to big exhaust housing on my GT35r.

My question is, is it possible to install a launch control on the stock motronic ecu ?
Maybe prj have the answer ?

I also have a another problem, after I have made some wot driving the afr goes down to 18-22 at idle and I have to rev it up a bit to stabilize the afr at 14,7.. could it be a vakuum leak somewere or my fpr that is jamming or something ? Anyone with the same problem ? It seems like it´s fuel related - like it looses fuel press.

Yes you are launching with throttle closed, of course you don't have any boost.
I have both fuel and ignition cut based launch control for Motronic, should make 2 bar stationary on the ignition based one.

Yeah, I have the launch control on Motronic by PRJ it works nice but you need a very good clucth , I wasted a stage 4 from South Bend with it only one launch and clutch disk was starting to eat the presure plate.Took a diferent route now, single mass and 707pp from Sachs .

Hmm.. is it possible to ship my chip over to u and get launch control installed in the tune ? But 2bar is to high, I want around 1-1,5 bar of boost(atmosphere)

I have no interest modifying software that was made by someone else.
Too many things that can go wrong.

You want around 1-1,5 bar of boost? Well what do you want? 1 or 1,5 bar... Hell of a difference.

Don´t know what´s best.. I will run a 707 plate with alu single mass flywheel and kep 4 plated zinter..

My WOT boost is 1,8bar right know but I will drive with 2bar of boost when the clutch is replaced.

I have never been driving with a launch control so i don´t know what launch boost is best, therefore -"1-1,5bar"

I will sen my ecu to turbo center for the installation of launch control.

Just qurious, how does the ecu know when the launch should be activated ? Is it via a button or some other sensor ? I saw some vids on youtube with guys playing around with variable resistors - but that is only rpm limited right ?
