drain needs to be applied to the system; the preferred method is disconnecting the alternator main fuse.
Battery load testers are also useful here too.
Watching the air fuel ratios change while the battery voltage drops, the dead-time table can be trimmed to
maintain the same stable air/fuel ratio. Injector dead-time can be viewed as a row graph. A smooth curve
needs to be maintained at all times.
NOTE: any change to the fuel pressure or injectors will require a recalibration of the injector dead-times.
Traditional Fuel Equation Mode Master Fuel Setting
If using Traditional Fuel Equattion mode the Master Fuel setting should be set so that the numbers in the
middle of the fuel table end up around a value of 50. This is to allow sufficient span of the numbers in the main
fuel table.
