A Sniper EFI system learns from all of them to get closer to the perfect ratio. There are many conditions beyond the mechanical setup that can affect how much fuel and air your engine needs, including speed, weather, temperature and elevation changes. There’s a very good reason for this - it never stops learning. The Sniper EFI has a learn percentage display, and many owners have noted that this percentage never gets to 100%. The ignition settings are also controlled with this function, allowing it to adjust the timing for optimal performance and fuel economy. In laymen’s terms, this means the Sniper EFI can make minor changes for different cams, bores, heads and other modifications. It does so using the included wideband oxygen sensor to acquire data about closed-loop fuel compensation and adjusting off the base fuel table. The unit comes preset with base settings that will get most engines running, and as you drive, the internal computer will adjust on both the short-term and long-term tune. This means you don’t need to ride around with a friend and a laptop tuning the car as you drive it in every possible situation. However, with Holley Sniper EFI management systems, the computer or ECU is hidden internally and the unit is self-learning. In many ways, it can be as difficult as traditional mechanical tuning. The biggest challenge of most modern fuel injection systems is having the technical savvy to tune the external engine control unit (ECU) for your driving style.
