WOT (Wide Open Throttle) Shifting
On automatic transmissions, these are the RPM points at which the vehicle
will shift when you are at Wide Open (full) Throttle. Raising these values
helps to keep the engine in the peak power curve after a shift.
(Hint: Raising these values may help improve 0-60 and quarter mile times.)
Standard (Std.) Shifting
On automatic transmissions, these are the MPH points at which the vehicle
will want to shift during normal acceleration. Positive values will cause later
shifts while negative values will cause shifts to occur sooner.
(Hint: Negative values may help improve fuel economy while positive values will improve performance.)
Shift Firmness
On automatic transmissions, these values represent a percentage change in
shift firmness, or in other words how “hard” your transmission will shift. A
positive number will cause the shift to be firmer. A negative number will
cause it to be softer.
(Hint: Firming up the shifts may help improve 0-60 and quarter mile times.)
Rev. Limiter
The Rev. Limiter prevents the engine from over-revving and causing engine
damage. If you set this value to 4500, you would not be able to rev the engine
beyond that even with the accelerator to the floor. Setting this value higher
can help take advantage of the power generated at higher RPMs. Setting this
value too high can cause damage to your engine. Also make sure to set the
Rev. Limiter at least 150 RPM higher than the highest WOT Shift Point or
you may experience erratic shifting.
