The Coil Phasing sets the firing order of the coils and must match the Injector phasing.
For the example shown above in Figure 12, Coil 1 and Injector 1 both have a value of
12. The corresponding values for Coils and Injectors 2-4 also match. See the
advanced calibration notes on phasing included with the EMS for more information on
Coil and Injector phasing.
NOTE: IT IS RECOMMENDED THAT TIMING BE CONFIRMED ON ALL CYLINDERS
BEFORE ATTEMPTING TO START THE ENGINE!
Series 2 EMS Coil Dwell
The coil dwell settings are listed below in Table 1. Dwell times in excess of those listed
in Table 1 will not improve spark performance and may cause the igniter and/or coil to
overheat. Click on the coil dwell tab labeled Coil Dwell in AEM Tuner and adjust the
tables as shown in Figure 13 below. The values in Table 1 should be entered in the
Dwell vs Battery table. The Dwell vs RPM table should remain at 100% for all engine
speeds.
