This Stage 1 Display allowing the driver to be informed of system activation, low pressure and low level faults during use & integrates with our failsafe if you are meth dependant to protect your engine.

This display is not suited specifically to a particular vehicle and is therefore Universal as includes a range of nozzles in various flow rates to allow for exchanging to reach optimal results on the intended platform.

This system also integrates a Fluid Level and System Pressure monitoring unit for the detection and warning of low fluid levels and system pressure faults.

The DevilsOwn™ Stage 1 Methanol/Alcohol Injection System was designed to make the system the easiest on the market to install. To accomplish this at the centre of the design is a custom 1-piece harness that has all the standard options and upgrade options available already pre-wired to make it as easy as possible with near to no design work required.

There will be some crimping of connectors required after the wiring has been installed as much of the wiring would be cut to fit.
