I have (it seems) the last upgrade on my cambiocorsa... I can not more make a canon launch in any mode: foot on the brake, 1st gear, foot on the gas full throttle. Before the wheels spin until I released the gas a little bit but today the car hiccup before to go strongly... I found a solution: 1st gear, left-foot-braking, 2000 RPM then release the brake/full throttle (with my new Michelin Pilot Sport II the wheelspin is largely reduced). BUT I am afraid to eat the clutch if I redo this kind of launch control. Your advices ???
