First Time Setup 61

operating at stable air/fuel ratios (a very precise AFR meter is required – a narrow band O2
sensor will not suffice), electrical 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.
Master
Master 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.
