Used for updated SD Card Contents on any 3. Windows Vista,7,8,10 Compatible. EFI software, ensure that your Holley Digital Dash is on the latest compatible software. Installing A Hyperspark Ignition. Can the Sniper be used with a dual plane manifold? While a single plan manifold can have better distribution for a throttle body application, The Sniper is fully capable of being utilized on a dual plane manifold. Will the Sniper be okay using a single O2 sensor? A properly functioning engine should not show a great variance between banks. If you choose, you can install an O2 bung in both banks to validate engine health and install the O2 sensor in the bank that reads slightly leaner. Once the Sniper is programmed, can I unhook the handheld? You can simply use the handheld for a tuning device and then unplug. What type of camshaft can I use? Hg Mercury at idle are acceptable. We actually recommend initially starting the engine with your existing conventional ignition system if it is in place and properly functioning. Then upgrade to timing control once you have the EFI installation completed. R or 700R4 automatic transmission? Yes, The sniper is designed with a stud location that will provide the proper TV cable geometry. How long does it take the Sniper to fully learn? The Sniper will never finish learning. Something as simple as weather, temperature, and elevation changes can dictate how much fuel an engine needs. It will rough in the base table in as little as 10 miles. A properly functioning engine with no underlying mechanical or installation issues is critical for proper operation. Can I use a Vacuum advance with the Sniper? Yes, the sniper has a timed spark vacuum port that will operate the vacuum advance. Is the Sniper approved for use in marine applications? Yes, Holley does have Sniper EFI Marine certified applications. Can I use the Sniper on a truck with dual fuel tanks? Yes, however, you will need to run a dual tank switching valve specifically designed for use with an EFI system that is pressure and flow rated for both feed and return lines. Do I have to buy a new distributor? No, The sniper EFI will run just the same as a carburetor would. However, if timing control is desired a magnetic pickup or Hall Effect distributor with a phaseable cap or rotor or Holley Dual sync distributor must be used. Can I run my MSD 6AL box with my Sniper EFI? In addition, you must ensure the MSD box is mounted a reasonable distance away from the Sniper throttle body to avoid any type of electrical interference. Will the Sniper work with my aftermarket drop air cleaner base that I used with my Holley carb? I do not have headers on my vehicle, only manifolds. How far do I put the O2 sensor away from my manifold? The same requirement applies to headers as well as manifolds. Do not install the sensor straight up and down or vertical. Do not install the sensor on the outside radius of any kind of bend in the exhaust system. Follow the diagram shown in the quick start guide for proper install. How do I know if my Sniper has fully learned? The learn percentage display, is the percentage of learning based fuel compensation. It does not indicate the percentage of learning completed. The closer the base calibration is to the engine s needs the lower the learning percentage will display. Why does my Sniper idle high after driving on the highway? RF noise is quite common in older vehicles using original ignition components. Can the Sniper control my electronic transmission, for example, a 4L80E? No, the Sniper does not have the capability to control any electronically controlled transmission. The base sniper kits are not setup for a boost referenced MAP sensor. However, all Super Sniper systems have a threaded boost referenced MAP sensor inlet on the base plate. How many vacuum ports does the Sniper have and does it have a ported vacuum source? It has two full manifold vacuum ports on the bottom rear side of the base. There is also a smaller ported vacuum source above these two. In addition, there is a full manifold vacuum source on the front that is shipped with a pipe plug. I just finished my installation and my engine will not start. You should then check the fuel pressure with the pump running. Line pressure should be approximately 58 PSI and the return line pressure should be less than five, zero is ideal. If the fuel pump primes when you turn the key to accessory, it is guaranteed that is not wired properly. Please refer to our troubleshooting guide. It is reliant on the data acquired by the included wideband oxygen sensor. A properly functioning engine and oxygen sensor placement are critical to learning and closed look as well as the longevity of the oxygen sensor. I installed my Sniper EFI, but how do I use my kick down for my C4 transmission? Tech kick down kit to work with a C4 transmission kick down. My truck was an original TBI and already has an EFI fuel system can I use my factory fuel system with the sniper? The filexlib.
