Default Anyone lose their launch control after supercharger install and tune?

Fellas,

I recently had a shop install an A & A Supercharger with tune (HP Tuners nguage). I've always done launches in Track mode in the past, but this time after the install, no dice.

In addition, I recently had the MSRC update done just prior to the supercharger install and tune. I ended up losing the MSRC update as well. Apparently on the first go around on the tune, everything was reset. The tuner informed me to have the MSRC update reinstalled at the dealer and everything should work. So I did. The good news is I got my MSRC update back, but still no launch control.

I've read past threads of others losing launch control after having the supercharger install and tune, but I would hear theories that with the car having much more power, launch control is incapable of holding the car down. It got me thinking. My setup is basic. No meth, no x-pipe, nothing. Just the supercharger. With that being said, my setup falls just short of Z06 power, and I'm sure the Z06 has launch control.

Can anyone offer insight and/or similar experiences and how it was rectified?

Thanks.

Mine is gone and I was bothered after I found out. ECS meth and Headers The 4 cyl mode is gone too but that doesn't bother me much.

I wish there was someone that had a way to bring launch control back without reverting to stock. I smoked a hellcat yesterday though so I'm not doing too bad without it I guess.

That seems to be the consensus. What a disappointment. I loved that feature.

Anyone have thoughts on optimal traction at launch - settings, RPM, etc.?

Start out at about 2200 rpm & go from that if the car goes on it face raise the rpm up about 200 more rpm until get gets out of the hole without braking loose. Then just play on getting into the paddle as it goes. Each car is a little diff even with the same parts in it so just getting a good amount of seat time in your car..

I would think if youre car is moving or rolling forward when trying to use the LC, youre not pressing the brake hard enough.

that's what I thought as well. I am literally all on it to the floor with all my weight lol. I mean I have used it before when it was stock and I know what needs to happen, I am very family with the procedure..its just not happening in D mode or 1st gear. It's only works in 2nd gear.

I did call my tuner..he said he never went into the launch control files, he was very surprised. Since you have a really high HP build, even tho its manual..does ur launch still engage in first gear? I think u did tell me u manually launch it since u get better times.

We don't even use it. Our cars will 1.3 60ft off the foot brake.

can you explain? So just floor it off idle? Cuz I did launch it manually at 1400rpm and let the brake go and it was like a rocket

I have AA SC kit and They tuned it with HP and I still have launch control M7, however I tried to use my no lift shift a couple times and it doesn't appear to be functioning. Surprisingly when I called AA they seemed to have no idea about no lift shift. For how Vette savy they are I was surprised that they didn't know anything about it. I don't see why any auto cars would or could use a high rpm to launch (4k rpm). I wouldlnt think auto cars would need anything but brake and gas.

On m7 manual corvettes, the rpms are much higher during launch control. On the A6 and A8, since its automatic..the torque converter multiplies the torque and the launch is typically 1800-2100 rpm and they launch with much lower rpms. When I used to use launch control in the past, I place the shifter in D, engage the launch control..my rpms stabilize at around 2000 and i let the brake go.

Now every since my car has been modified..the only way to keep the rpms stable is in Manual paddle shift mode and 2nd gear. First gear and D mode, the car just rolls forward and the rpms wont stabilize..meaning launch control cant engage. I am assuming, since their is so much more torque and HP now than before..the computer cannot control it and it can make stabilize the rpms for a proper launch.

I have an A6 and my launch control still functions...but it's useless. It launched substantially better before the upgrades. Now it launches like a dog. I'm much better without it and just rolling into the throttle.

I can't see how any launch control is going to work after mods. The torque curves will have changed so much that the pre programmed launch rpm, throttle input, timing, etc would be out by a mile! You would probably need to 'tune' the launch control for the new torque curve.
