How Does It Work? 

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. So, if 
the  last  1/4  of  a  turn  of  the  crankshaft  (one  cylinder)  is 
faster  than  the  average  of  the  last  full  revolution  (4
