Auto (r) so you can fully concentrate on keeping the car straight. I find that I need to engage the racerom on traction control as Nissan cuts in too often. So traction control off (if you have ecutek mapping). Then set suspension to comfort to allow the car to squat a bit and get traction on take off. Best settings for launch control is not to launch with rpm to high to minimise wheel spin. I find 2700 -3200 best and boost offline as low as possible like 0.5 - 0.7 bar.When attempting this, is it best to leave the car in auto mode, or manual?
