Hi guys,
I need a bit of help in tuning my cars. Currently I am trying to tune my One:1 and my problem is in high speed sections like straights or long curves, the car “reacts” too much on bumps something like bouncing repeatedly resulting in loss of contact to the ground. I am using CW’s calculator as my base tune. I downloaded other people’s tunes here and they seem to have the result I want. I just want to make my own good tune so I can edit it anytime I want.
Thanks! 
Sounds like you need to soften things up. Whether that’s spring weight or bump or ARB or height I couldn’t tell you without knowing your build and tune.
