Makes a change from dealers taking the PIS......

Good post, and the quicker you want your clutch to operate, you reduce the PIS, raise it for smoother take up and changes.

i've owned three 360 F1 modenas, and the way the F1 shifted on one of them just was not as "snappy" as my others. i always run my 360s in "sport" mode because i like the more aggressive action of the F1 shifts.

i first noticed something not quite right while starting off from full stops. it felt like the clutch was not engaging as quickly as it should (almost like the clutch was being released too slowly). likewise on downshifts it felt like the car was "coasting" a couple seconds before the clutch was released after the downshift. nothing drastic, but just not "aggressive" shifting like my other 360 F1 cars.

i took it to the dealer, and i was amazed to learn that there is a simple adjustment called "PIS for point of initial slippage) that they can easily adjust. on the older 360s they have to throw a wrench on something to make this adjustment. but on the newer models (mine was a 2002) they plug your car into the computer and set a PIS parameter. voila. problem solved. i wanted to mention this "PIS adjustment" in case it might help others with similar concerns about their F1 shifting performance.

btw, the mechanic explained to me that each car is slightly unique so the default PIS value that is set at the factory (although usually a good setting for most cars) may not be the best setting for your car. so if you think your F1 may not be shifting as aggressively (or i suppose too aggressively) as you would like you may want to ask your dealer about adjusting the PIS. it only takes five minutes.
