Hi Members, Hoping someone may be able to explain how the F1 systems controls the initial clutch engagement? When starting from a standstill and depress the throttle very slowly you mreach a pointn where the clutch starts to engage but the revs have barely raised if any. Can someone explain how this take up position is sent to the F1 control system, is it that throttle pedal position sensor is not only controlling the throttle but also feeding the computer with the engagement position or is it another independent sensor or microswitch that is performing this control? Is there a detailled manual available that will describe the operation of the F1 system in detail also describing how it is controlled via the various sensors Your feed back will be appreciated, thanks in advance Kipper
The PIS (point of initial slip) is set with an SD during clutch installation. It is adjusted over time as the clutch wears.
Kipper- You can download a 360 workshop manual at ferraridatabase.com and it has a pretty good explanation of how the system works. In general there is a clutch position sensor that tells the system where the clutch is. The F1 cars also have an extra angular speed sensor that sends information to the F1 ECU/TCU. Like John said, the point of intital slip is set using an SD2/3, either by initiating an auto adjust in early or late 360s, or manually in later cars. The digital throttle both passes information to the F1 ECU/TCU and receives information (when to raise revs for downshifts or cut the throttle for upshifts) from the same source. All in all, it is just a more sophisticated version of a golf cart, with more gears, and uses the exact same transmission and clutch as the three pedal version. Shifting is done by applying 800-900 psi hydraulic pressure to the shift forks. Only the electro-hydraulic shifter, throw-out bearing, clutch position sensor, and extra angular speed sensor are different. Taz Terry Phillips
