Additional information for FAST™ EZ-LS™ / FAST™ XIM™
As mentioned above, with a traditional single coil engine using a crank trigger or distributor, the ECU
expects crank signals at TDC (0° BTDC). When used with a FAST™ EZ-LS™ or FAST™ XIM™
ignition system, the ECU expects the crank signals at different locations depending on the make of the
engine. For example, the ECU will expect crank signals from an EZ-LS™ ignition to occur at 50°
BTDC so that will be the base setting on the Timing Verification screen. (“50.0” instead of the “00.0”
in the previous example.) From there, it can be adjusted up or down as described above. If timing was
a little off like in the previous example (timing light showing 23° BTDC instead of the 20° BTDC the
ECU is shooting for), this setting would end up being raised from “50.0” to “53.0”.

IAC Calibration
Adjust the idle screw on the throttle body until the indicator in the slider is in the red target box. This
is adjusting the resting position of the throttle blades so that the idle motor (an electronically controlled
stepper motor that allows air to bypass the throttle blades) is operating in the preferred position. This
ensures that the idle motor has enough range of motion to help bring the idle speed up or down as
needed.
