Wow, another post gone bad! But is it good enough to film for release on Video?
Interceptor should not be this difficult to set! Install is by far the hardest part. 2 sets of instructions are included with it and there are arrows on the device itself for increasing or decreasing line pressure and delay, although they are opposite one another since they are the same pot on different ends of the circuit board.
Hard, abrupt shifting will ONLY be caused by too much line pressure, especially if it did not do it BEFORE the Interceptor was installed. ‘00/01s are more sensitive to line pressure increase as they appear to run a higher pressure from the factory so start out with a slight turn of the pressure pot to slightly increase it. If you had a hard shift (up or down) BEFORE you installed the Interceptor, this device will NOT fix that and will probably make it more noticeable. IF that is the case, you ought to have the tranny looked at by a professional and that probably means NOT the dealer.
Delay setting will NOT cause a hard shift and should be set at 100% delay for optimum use. It is very difficult to actually feel the delay but acceleration times will be improved. DELAY does NOT affect downshift ability or timing, only the lockup of the torque converter AFTER a shift has occurred.
