The
Non Self-Learning systems, like
our Sportsman series, periodically compares the rate of
acceleration of the driveshaft to an Adjustable Fixed Rate
(AFR), known as Threshold. If the DS RPM rate of change is
in excess of that Threshold, then a correction is made.
The comparison is made every 1/8 of a turn of the driveshaft.
Basically, this
Patented system looks for spikes in DS RPM
that are caused by wheel slip.
If these spikes are large enough, then a correction is made,
reducing the slip.
By adjusting the Threshold, the user
can tune the system to correct larger slips, while not reacting
to smaller, harmless, slips. This means the user does not have to
figure out the desired DS/Engine RPM and build a preset “Dot
Plot” (anybody got a crystal ball?).
A typical 1/8th mile car turns the drive shaft about 300 times in a 660
ft. run.
At 8 triggers per rev, that would be like building a “Dot Plot”
w/ 2400 dots, and ¼ mile cars turn the drive shaft about 550-600
times in 1320 ft. run. At 8 triggers per rev, that would be
4400-4800 dots.
Self-Learning systems, such as our
Lite and Pro series, compare the rate of acceleration of the
drive shaft to a calculated threshold value that is constantly
updated based on the average of the previous measurements.
This update occurs on every drive shaft revolution. So, if
the last 1/8 of a turn of the drive shaft is faster than the
average of the last full revolution, then a slip is detected.
Through this very advanced
Patented process, the
system constantly accounts for track conditions, tire condition,
etc. to constantly update the internal settings. These
settings are updated as many as 800 times a second to keep
the unit calibrated to exactly the right settings regardless of
changing conditions.
Basically, the system learns the
average rate of acceleration of the drive shaft, and if there is
a sudden spike in RPM above that learned rate, then a correction is made.
With the Self-Learning feature, the user doesn’t have to
try to figure out the DS RPM rate of
change and set a “Threshold”, the system does it for you, every
drive shaft revolution!
The user does have an adjustment
referred to as “Mode” that sets the overall sensitivity of the
system to make a correction based the extent of the tire slip.
By adjusting the Mode, the user can tune the system to correct
larger slips, while not reacting to smaller, harmless, slips.
