System Tuning and

Nozzle Selection

The Straight-Shot and Double-Shot sys-

tems come pre-packaged with several

different nozzle options that cover a

wide range of applications, but some

controller setting optimization may help

dial in your system for your intended

usage.
When configuring for maximum perfor-

mance, the largest kitted nozzles should

be installed. If engine hesitation, misfir-

ing, or early ignition (excessive combus-

tion noise or rattling) is experienced,

reduction of the commanded pump duty

cycle, along with raising the boost refer-

ence points will reduce the injection

quantity to help reduce this. If required,

reduce the nozzle size to make large

changes in injection quantity.
If typical fluid consumption is higher

than desired, increase the initial boost

reference point to decrease the fre-

quency with which the controller acti-

vates (turning on only at higher load).
If more frequent injection is desired (for

instance, when combating a constant

high-EGT condition with distilled water,

or offsetting diesel fuel usage with a

water-methanol mixture), a proportion-

ally small jet should be used, with a

reduced initial boost reference point

and low starting and final pump duty

cycle values (a ‘flat’ response curve).
