Did you know that you can unlock even more tuning capability in your Holley Sniper EFI System?  It's true!  Some of the more advanced tuning features are not available using the handheld touchscreen display that is included in the Sniper EFI System, but the are available through the Holley Sniper EFI Software that is available as a free download and runs on any PC with a USB Port using the Windows Vista,7,8, or 10 operating system.

To get started you will need this adapter-harness convert the CAN bus connector to a USB plug.  Just plug the USB plug into your PC/Laptop and the CAN bus connector goes where you have your handheld display connected. Adapter cable is 8 feet in length.

We also have CAN Bus extensions and Y-cables--check them out!
