Install Your Own Custom In-Dash Fuel Injector Duty Cycle Meter

In Dash Fuel Injector Duty Cycle Meter

An accurate Fuel Injector Duty Cycle Meter is an absolute must if you are doing any kind of fuel related performance upgrades to your car. Such as Supercharging, Increasing Turbo Boost Settings, Adding Boost Controllers etc. This unit takes the output from your existing Car's Number 1 Fuel Injector Signal and displays the results on 10 LEDs. The LEDs Light Up as the Fuel Injector Opens. Displays 10% - 100% Injector Duty Cycle. They ramp up until they are all on at 100% duty cycle which is wide open. It lets you know whether your car is running at it's optimum from a Fuel Injector perspective. If they are always running over 80 - 90%, you may need larger injectors or a modified program for your ECU. You can mount the LEDs anywhere you like. They can be fitted right into the car's dash board if purchased in one of their kit forms. The complete circuit board is so small it can easily be concealed. This Meter used in combination with our Air Fuel Meter (Also available and described in another area of this site) gives you all the information you need to ensure a perfectly tuned Air Fuel System. In addition they look great on your car's dash.

If you are not handy with a soldering iron, you can order the complete unit in a small slim enclosure that can be attached to your dash with double sided tape.

Please refer to the chart at the bottom of this page for detailed information on the functionality.
