At the 2023 SEMA Show, Holley announced that Bluetooth was coming to Holley’s Sniper 2, and everyone was excited. I’ve been lucky enough to see it in action during testing and can tell you that it is a very handy feature, but there might be more reasons that you realize. With the Sniper 2 Bluetooth module, you can use an IOS or Android phone or tablet to see all the data from your Sniper 2 EFI system. And not only can you make the gauges show on your screen, but also have multiple choices for the look and layout. And yes, you can tune directly from your tablet or phone.

With this setup you don’t have to run traditional gauges or a digital dash, but you certainly can. What I think is one of the more useful features of the bluetooth module is that you can have your gauges and tuning ability in your hand while anywhere around the vehicle. That means you don’t have to be inside and have a second set of hands outside the car. You can instead stand up front, make adjustments, and tune, all while getting live info on your engine. I love it.

Here’s all the info from Holley.

BOWLING GREEN, Ky. – April 30, 2024 – Holley Performance Brands (NYSE: HLLY), a leader in automotive aftermarket performance solutions, today announced the addition of a Bluetooth module for its Sniper 2 Electronic Fuel Injection (EFI) conversion ecosystem.
