Locate this number and write it down for future reference when programming theconsole.Calculate the Valve Cal ValueThe Valve Cal figure is used to control the response time of the control valve motor to the change in thevehicle’s speed. After operating the system, this number may be refined. The initial recommended controlvalve values are:• C-SD (standard valve) = 2123• C-FC (fast-close valve) = 743• C-F (fast valve) = 743• C-P (PWM valve) = 43• C-PC (PWM close valve) = 43FIGURE 3.
