The Race-Spec Billet DC5 TYPE R Shifter with Pro Shift Cut is currently compatible with AEM Infinity, Haltech and Motec systems which all have programmable ecu inputs. The programmable interface unit will be needed for K-Pro applications and is purchased as an add-on option. We want to note that the Pro Shift Cut is not a bolt on option for existing shifters. It is only offered as a complete shifter with the sensor already mounted in place and ready for use. The shifter comes with a set of preset shift stops, to prevent over-shifting and a centering tool for perfect setup of our adjustable K-Tuned race-spec shift cables.
