With the ignition system now calibrated and firing, enable (and connect if disconnected) the fuel injectors. With fuel enabled, crank your engine and adjust fuel until the engine starts. Adjust your fuel trim and fuel maps at the idle range and load until the engine idles smoothly. Typical engine idle RPM will be 1000 RPM at about –60 to –80 kPa of vacuum. Check that your ignition timing is still accurate and firing at the angle that is set in the Lock Timing parameter.
You are now ready to tune your engine.
