An injector control system for a coiled tubing unit includes a programmable logic controller arranged to receive a signal related to sensed parameters of a coiled tubing injection operation; a traction pressure control hydraulic circuit operable to adjust hydraulic pressure provided to at least one traction cylinder in a coiled tubing injection head; a motor pressure control hydraulic circuit operable to adjust hydraulic pressure provided to at least one motor of the coiled tubing injection head; and at least one of the traction pressure control hydraulic circuit and the motor pressure control hydraulic circuit including a proportional control valve in receipt of a variable electrical signal from the programmable logic controller. The programmable logic controller adjusts the signal delivered to the proportional control valve throughout the coiled tubing injection operation as dictated by the sensed parameters.
