<strong>6:00 p.m.:</strong>Even though we really like the fact that you don’t need a computer to adjust the air/fuel ratio, we also like that the Atomic EFI system lets you easily adjust a bit of fuel delivery in a way that makes it hard to mess things up or get lost. In the Advanced Setup screen, you can adjust the air/fuel targets for idle, part-throttle and wide-open-throttle. This lets you richen or lean the engine under these three separate conditions. You can also give the engine more or less fuel to improve throttle response using the Pump Squirt feature that mimics the function of a carburetor squirter. We messed with both of these on our engine and made improvements in drivability in about 5 minutes.
