Increase launch time with transmission ratios?

[Samareye]

Hey, I'm pretty new to tuning, and the transmission confuses me. What do I do in order to get a faster launch time out of a car, raise or lower the ratios? What exactly is it that raising and lowering them do - aren't they reversed somehow?

Thanks for the help

You can make your first gear shorter to get a better launch (assuming you will not be getting excessive wheel spin). Moving the slider to the right for first gear will give it a larger value and make it shorter. You will accelerate faster, but maximum speed in 1st gear will be lower.

You will see how this works in a car with about 150 horsepower and soft tyres.

Having 1st gear set too tall is a bit like trying to launch from 3rd or 4th gear. Having 1st gear set too short and you will waste time with wheel spin, maybe waste time bouncing on rpm limiter, then waste time shifting to second at a low speed.

To get a fast launch in a high power car you might have a 1st gear that can reach 100km/h+ (60mph+). In a low power car you will want a shorter gear.

Wow, perfect answer to my question, thanks a lot! I'll experiment with that
