One of the benefits of electronic engine control is that designers keep coming up with ways to make it better. As good as Holley’s original Sniper throttle body EFI has proved to be, the engineers from Bowling Green, Kentucky, couldn’t resist improving it with the Sniper 2. This is much more than just a superficial face-lift, and it will require most of this story just to outline all the changes, so let’s get cracking.
According to our Holley sources, the software is largely the same as the original Sniper except for the addition of the wireless Bluetooth connection and new transmission control–both of which we will detail in a moment. More importantly, the new ECU has been updated to be more robust in filtering out radio frequency interference (RFI), which can be a great benefit to resist electrical noise that is common with CD high-voltage ignition systems.
