Its a computer chip with 4 pots on it. When wired into the harness to the ECM (on fuel injected bikes) it acts like the jets on a carb. 1 pot adjusted low fuel, 1 for mid fuel, 1 for full throttle fuel, and 1 for adjusting fuel at acceleration kind of like an accelerator pump.

It increases the injector pulse width , the time the injector is open.

When I saw DFO, I thought you were talking about "Done Fell Out"....

So how much will a digital fuel optimizer improve a stock motors performance?
