    Talking Sniper EFI Installation & First Start

    The Sniper EFI was easy to install & program. This is how easy it was to do. Enter cubic inches & number of cylinders, and it started right up & idled really good. Ready to do some driving, after it Learns just a little more.

    Since we already had the fuel system in place, and the MSD ignition in place, it only took a few hours to run everything & fire it up.

    That's a good testimonial. Thanks.

    Hi Pakroger, I bet you're glad to see the PowerJection3 go. Just curious, can the Sniper EFI be connected to a laptop or can it only be tuned with the handheld displays?

    It's supposed to be laptop tunable with a Holley USB/CAN dongle (purchased separately). I don't know if that's been released yet.

    If you want to connect it to a laptop, you can, but it is mainly for nitrous and some other items. From what we have found out, the handheld programmer that comes with it, will do everything that you want & more. It's so much easier than the PowerJection3. I can't say how easy it was to get the vehicle started, and to run at an idle that we wanted. As for the PowerJection3, it was very temperamental.

    If you have the same luck that I have had with Holley, you're going to be very happy. Let us know how it goes once you start driving it.

    That would add a lot of flexibility to the system. There are always those guys that want to go that one step further.

    I just received a reply from Holley EFI. They're finishing the Sniper EFI (laptop) software & its USB/CAN dongle now. It's optional, and it should be available soon.
