Spinning the tires not only makes the car harder to
drive, but it also causes higher tire temps and
excessive tire wear. Lifting off the throttle or counter
steering to correct for this 5% mistake, not only
upsets the rhythm, it slows the car down!
Typically, if a driver makes a 5% mistake with the
throttle, he/she has to correct 20-25% to fix it. But if
the tire slip is detected within one cylinder worth of
crank rotation, as the Davis Technologies systems
do, then a small reduction in power can reduce or
stop the tire slip.
The Non Self-Learning systems, such as our TMS-
750, periodically compare the rate of acceleration of
the crankshaft to an Adjustable Fixed Rate (AFR),
known as Threshold. If the Engine RPM rate of
change is in excess of that Threshold, then a
correction is made; therefore, reducing the slip.
The comparison is made every cylinder (1/4 of a turn
of the crank shaft).
Basically, this Patented system looks for spikes in
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 driver can tune the
system to the desired “feel”
Self-Learning systems, such as our TMS-750-SL,
TMS-5500-SL, and TMS-9500-SL series, compare the
rate of acceleration of the crankshaft to a calculated
threshold value that is constantly updated based on
the average of the previous measurements.
This update occurs on every crankshaft revolution.
