Jake Brake. The Jake Brake function is used to increase exhaust backpressure
when lifting of the throttle by using the Variable Gate Turbo control. This function
increases the engine braking, and is useful when towing. The driver feel of this
function will not be the same as an aftermarket exhaust brake, as it is only a
limited amount of back pressure that can be created in this method.
Locked At CT (Closed Throttle). This function locks the Torque converter on
deceleration when the throttle is closed. This, combined with the Jake Brake, can
help increase engine braking when towing heavy loads.
Aggressive Tow/Haul. By selecting the tow/haul button on the shift selection
level. This function will allow the transmission to downshift more often when
towing a load. It applies a more aggressive downshift/upshift when towing to help
with vehicle acceleration and braking.
Locked in 1-2-3. This function allows the PCM to lock the torque converter in 1
st
,
2

gears. This is something that should only be used on a drag strip
application, and if used on the street, There will be drivability problems when the
engine RPM’s are too low.
Firmer Shifts. This option is a global shift modifier, and will cause more aggressive shifting
on all shift types, part throttle and WOT shifting will be altered with this option. NOTE. Some
customers will not like the super hard shifting, where others do.
