Harness Overview
Suits naturally aspirated, force-fed carburetor, or mechanically-injected applications from street cruiser to blown alcohol promod. It comes with color coded and labelled wires that match the detailed wiring diagram for a confusion-free construction process. The wiring diagram is accompanied by the full ECU manual and Software located on the CD or USB key provided with the ECU to refer to while completing your installation and configuration.
ECU Overview
Ideal for non-EFI, mechanically-injected and carburetted drag racing vehicles. The VMS is a one-stop, one-point-of-contact solution for ignition timing control, boost control. nitrous control, staging bump-and-creep control as well as on-board data logging. Ideal for non-EFI, mechanically-injected and carburetted drag racing vehicles.
