Full throttle shift
Full throttle shift uses the same clutch switch input as launch
control. When the vehicle is moving and your foot is on the
clutch, the rev limit is dropped to around 6000 rpm (this can be
changed). This allows the rpm to be matched while shifting gears
while keeping the throttle wide open, which speeds up gear shifts and
helps keep turbo chargers spooled up. Great for improving those 1/4 mile
times, and sounds pretty cool from outside the car too. Here is an in car
video of a full throttle shift.
For bracket racing tests have shown that ET repeatability to less than
1/10th of a second is achievable without the use of an automatic.
Apart from all that. It is a lot of fun.
As of 3/1/05 all s200's will include the 3-step option at no additional
charge. However the user will have to locate a clutch switch from a store
like Autozone. The part number is JA413 for a Wells stoplight switch.
