Verified: 6HP trans, launch control Limits torque while your foot is on the brake and at wide open throttle..When you release the brake you will go back to your normal 1st gear power level. (a.k.a. load request)

What to do: Make sure launch control is enable in the app, put trans. in S or M mode, Apply brake firmly, go to wide open throttle immediately. I was hesitant and in my graph you can see the load request went above the set limit in launch control because I was still at part throttle. Once I went full throttle brake on, the set torque limit in launch control kicked in.

This was my second attempt at using launch control. The first time I used the recommended 350 ft/lbs and it immediately spun the tires.(all season 255/40-18's) The second time I dropped it to the lowest setting (the recording on datazap). 212 ft/lbs or so, I have gone up one click, around 238 ft/lbs. I will continue to do this until in spins too much and then lower it back down.

I also just pressed the DTC button once during this attempt. Not sure what is recommended or will be best. Just had the DTC showing, did not disable DSC.
