Holley Sniper EFI
Pre-Programmed Startup Guide
***** IMPORTANT!!!! *****
***** Your Holley Sniper System has been Pre-Programmed, Tested, Tuned
Specifically to your Engine. Starting a New Global Configuration File or Startup
Wizard may accidentally overwrite existing fIles and delete valuable learned
information from your Dyno Testing. *****
*** Please proceed as follows to upload your Engine’s Specific File ***
1. Upon powering up Sniper EFI will automatically show Home Screen Menu
on Handheld Controller. From here you will select the “FILE” option.
2. After opening “FILE” you will then select “Global Configs”
3. From the “Global Configs” menu you will then select your Engine’s File
(example: BLUEPRINT 347.sniper) and click “Upload to ECU”.
*****NOTE*****
***Global Configuration File labeled (Ex: 4150_4_ZBA.sniper) is the initial
startup file used to start your engine but contains no learned values from
testing. The File Titled “Specific” to your Engine, is your Tuned File and
should be left un-modified as a base file for your engine. If modifications
are made to this file it is suggested to save changes as a “New Global
Config File” and Re-Title to differ from other Files.***
4. After selecting “Upload to ECU” then select “OK”
5. Select “OK” again and then Turn off Ignition for a Minimum of 4 seconds
before Powering back on.
6. After powering back up Holley Sniper Handheld will then display “Saved
Global Configs” Screen. From here select “Home” in the bottom left corner
of the display and proceed below... Your “Tune” has now been Uploaded!!
7. From the “Home” screen you will then select “Monitor”
8. Then Select “Multi-Guage”
9. Select “Sensors”
10. Congratulations!! With the “Multi-Guage” Monitor Display on the
Handheld, You are now ready to START YOUR ENGINE!!!
*** IMPORTANT - PLEASE REVIEW ***
Pre-Start/Start-Up Check-List
1. Holley Sniper Power and Ground Wired Direct to Battery. (battery lead’s
may be shortened but never lengthened!!)
2. Sniper EFI Requires a “CLEAN” Key-On Power Source and “MUST” Differ
from Coil or any other High Current Components. This applies to any
Timing Control Components as well! (example: Electric Fans , Ignition Coil,
CD Box, Alternator, etc.) Remote Relay may be required for some
applications.
3. Be sure to Keep all Sniper EFI wiring routed away from any High Current
Components. Especially Spark Plug Wires and Alternator!! (High Draw
Components tend to give off Radio Frequency Interference when in
operation and can cause interference in the Sniper Systems
Communication with the Engine Sensors.) Shielded loom may be used to
help prevent R.F.I. in certain applications.
4. The “Blue” Fuel Pump Wire must go directly to Fuel Pump (Inertia Switch
can be Spliced inline)
5. Verify Engine is Receiving 60 psi of Fuel Pressure with Key ON.
6. After starting Engine Verify Engine is Receiving a “Minimum” of 60 psi Fuel
Pressure while Engine is Running. (Adjust Handheld Settings to “ANY”
Increase in Pressure.)
7. With Air Filter on, “Multi-Gauge” Monitor Open, and Engine Running. Allow
Engine to warm-up until a “Minimum” Value of 165 Degrees is shown on
your “CTS, F” box located on the “Multi-Gauge” Monitor Screen.
8. At 165 Degrees (F) your Engine is now in Closed Loop.
9. With Air Filter on you will now want to Verify that your Engine is Receiving
the Proper Amount Idle Air (or IAC Pos % as shown on Display) for your
setup. This “Value” should be somewhere between 5-10% in the IAC Pos %
box of your “Multi-Gauge” Monitor. If value is above 10% Adjust Idle Speed
Screw to open Throttle Blades until Proper IAC % is achieved. If “Value” is
less than 5%, use Idle Speed Screw to then open Throttle Blades until
proper IAC % is shown. (This “Value” will always fluctuate with Engine
Running, so the “Rule of Thumb” is to aim for 7-8%)
10.After Reviewing and Verifying this Check-List you are now ready to get out
and enjoy your Engine!
