How Does It Work?
The Non-Self-Learning systems, like our TC-3,
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 1/32 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, based on the threshold
setting, then a correction is made thereby 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?).
Self-Learning systems, such as our TC3-SL,
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 1/32 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 1000 times a
second to keep the unit calibrated to exactly the
