Self-Learning systems, such as our CT2-SL, CT3-SL, CT4-SL and CT5-SL units, 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 cylinders), then a slip is detected.
Through this very advanced Patented process, the system constantly accounts for track conditions, tire condition, even driving style to constantly update the internal settings. These settings are updated as many as 200 times a second to keep the unit calibrated to exactly the correct settings regardless of changing conditions.
Basically, the systems learn the average rate of acceleration of the crankshaft, and if there is a sudden spike in RPM above that learned rate, then a correction is made. This allows the system to adjust to the Correct settings even if one corner has more grip than another, or even one groove to another.
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 driver can tune the system to the desired “feel”.
