Searched for this info but could not come up with any solid info. The tcu in my 99 360 is a cfc201f.05 part #191701. My clutch engaged at a lower rpm just off idle when i bought the car years ago, now i noticed that the engagement occurs at a higher rpm, somewhere around 1500 to 2000. I am assuming this is due to some clutch wear after about 5000 miles. I would like to adjust the pis. Could anyone tell me if this could be done with the x431?
