The Buell ECMs use separate maps for front and rear cylinders, shown in Figure 1 and Figure 2 as Front Fuel Map and Rear Fuel Map. The fuel map is read as a function of throttle position and engine speed. This type of fuel control is known as Alpha-N, where Alpha refers to throttle angle and N refers to engine speed.

Can a corroded ECM cause a car to fail?
If the wires to the transmission or fuel injectors become corroded, they can lose conductivity, leading to a failure. Fortunately, these issues can usually be resolved by replacing the corroded wires. If one of the wires shorts out to the frame, the ECM may fail entirely.
