Has anyone else lost launch control after having a supercharger installed/tuned? I tried to use it the other day and it seems to be gone.

Its gotta be something in the tune

Define lost in more detail?

Meaning I don't seem to have it any more. I had used it a few times before the blower install. Tried to use it after and nothing. The car tries to do a brake stand.

What blower and who did the tune? I havent tried the launch control since my SC install.

Are you certain you are doing the correct steps and have the car in the right mode? I did not lose mine. It would be very odd for that to just go away.

You have to press on gen brake HARD or it won't engage.

Do you have rear tires without sensors? That'll do it too

Same issue here. Launch control hand brake. Did you ever figure out why or a fix? All my launches need to be with t/c and stabiltrac off

Jeremy Barnaby

Me too! Anybody have any ideas on how to fix or if this is a known problem. A&A did my install. I have their baseline package.

I have A&A installed by them on my 2014 z51 A6 and my launch control works

My car is an A8 and I just installed a 2650 and am making 700 rwhp, the launch control feature is gone. I put it in Tr mode and turn off the traction control, doesn't matter if it is in Sport 1 or Sport 2, it bucks and won't grab. Tuner states it's too much power for the rest of the components to handle. I had the TCM tuned with it too.

With my stage 2 E force the LC worked with the Edelbrock tune. I’ve done other mods and tune recently and the car just blows the tires off using LC now.
