REAL: meaning not just bang bang pop flame for the kids, but BOOST from the start and holding.
Me7.5 used in longi 06A 1.8T

As soon as we drop clutch, car chokes and loosing lots of time during the start.
Heard that there is a separate box available (300 Euro) to accomplish building and holding boost during start (and while shifting).

Good tip, thanks. Will check with the 'bit geek'.
I assume LC will certainly create misfire and knock event as seen by the sensors/ecu, correct? And NOT disabling during LC will infere.

The code that widely available on here will build boost, not massive but 0.5 bar is pretty easy. It's 80% there.

Like he said, you need to disable KR to get it to last.

You can make as much boost as you want.
Most likely it is not set up and implemented correctly.

I wont ever be fluent as many of you are with assembly, but always eager to learn..

So KR (knock) needs to be completely disabled (cannot be done just for LC)?
That is kind of risky.
Means: want LC, can't have knock control?

You disable it while LC routine is running lol not all the time.

Where in here did you intercept the code?

What architecture is the ME7?

Or were you able to modify a map to accept the noise levels?

I have a working solution for actual launch control including ignition retard, routine disables knock detection and lambda detection during routine. I can patch a file for you but not for free.

This is a DIY forum, not a marketplace.

I wouldn't be here if I had money to blindly dispose of.

First off, DIY implies you have done something yourself, all Ive seen from you so far is asking for handouts. Secondly, I've been here A LOT longer then you buddy, and Ive contributed A LOT to this forum, if I want to give myself a plug I will Grin
