Outputs
Fan #1 On
Temperature
The OUTPUT screen allows for the Fan #1 and Fan #2 ON and
OFF temperatures to be adjusted. The ON temp needs to always
be a higher value than the OFF temp. Use a difference of at
least 5 degrees so they aren’t cycling excessively. In Sniper Kits
these are ground outputs that should be wired to trigger a fan
relay. NEVER wire them directly to the fans! Preset to 190°F
Fan #1 Off
Temperature
Preset to 180°F
Fan #2 On
Temperature
Preset to 205°F
Fan #2 Off
Temperature
Preset to 195°F
AC Shutdown Max
TPS
The AC Disable value is a TPS value above which a ground
output is sent out to deactivate the air conditioning compressor at
wide open throttle Preset to 65%
Engine Setup
Number of
Cylinders
Set the number of cylinders your engine has.
Engine
Displacement
This value should reflect your actual engine size. The base fuel
table calculates proper fuel flow based upon this value.
Cam Type
Display only, does not change anything in the tune
Sniper Setup
System Type
Sniper Part number must match selected parameter
Fuel injector flow
Sniper injectors flow 100 lb/hr @ 60 psi. This value should not
be changed.
Actual system fuel
pressure
The internal Sniper regulator is set at 60 psi. If you are using an
external regulator instead of the internal regulator, ensure that
this setting matches your external regulator's set point.
Progressive TBI
enable / disable
Not available with 4 injector Sniper kits
TBI secondary
blend
Not available with 4 injector Sniper kits
Ignition Setup
Ignition Type
This shows the RPM input type (Coil (-), CD Box, Magnetic, Dual
Sync)
Reference Angle
Only shown if Magnetic or Dual sync is selected. This is the
value in crank degrees of the distributor's crank pulse. These
values are preset in the base calibrations and should not need to
be adjusted.
Main Rev Limiter
If Sniper is being used for Timing Control, this is the main over-
rev value. This rev limiter is Spark Only
Inductive Delay
Use this value to sync timing at higher RPMs. These values are
preset in the base calibrations. Some ignition modules may need
this number altered if the commanded timing does not match the
commanded timing as engine speed increases. If the timing
starts to retard, this number can be increased in order for the
timing to match. If the timing starts to advance, this number can
be increased in order for the timing to match.
Output Dwell
This value changes the points output dwell time. This value is
preset in the base calibrations and should not need to be
adjusted.
Note: Values above 2.5 can lead to premature coil driver failure.
