Time for a new video. Website and file are looking different

[TheReinoPaasonen]

This was lifesaver today. Brand new sniper had firmware failure and with these instructions, I was able to upload new one and get sniper started

[peturkristinsson]

I like this guy, he explains this very well, and speaks clearly, and he uses no extra stall words like and "um" like so many other youtube people. Thanks

[XXMACHX]

Wow that was simple. 5 minutes and you’re done. Website has changed but very easy to navigate. Thanks

[NoFilterPhotography]

y'all do such a great job on these videos! Seemed like mine was way out of date, but up to version 3 now! Appreciate these videos!

Why did the update get rid of the progressive throttle settings? I had mine dialed in.

Why does the base stock cam tune vs wizard stock cam tune have different compensation limits and table resolutions

If i just purchased a sniper system March 2022, installing this week, do i need to update the firmware or it should be good to go?

[rancherodave]

Does the newest firmware update have a wizard for e-85 thought I read that on the sniper forms.

[scarlettsgarage]

My unit is new and doesn’t get passed ‘searching for ecu ‘ on the handheld, will an update fix this ?

[dieholdendie]

good video, what does the firmware update change?

[videodvd]

If you purchased your sniper in April from Holley do you need the update?

[cfmechanic]

I see there is firm where for the ecu and also for the handheld. Am I supposed to update both

[bradboyko]

After I go to upgrade ecu it says file not found when I just downloaded the new version on the sd card

[JD-gomh]

I went to the saved gcf under fw0100 but it is empty. I located the file under FW0101s why is that?

[EAGLNE]

Does this same basic concept apply to Terminator and Terminator Stealth as well?

[anthonybelvedere]

my issue is that my FWU file still says internet explorer beside it. my handheld says the handheld has no fwu files

[eagle]

My sniper ecu kept shutting down on me, at certain rpm the screen would turn red and no values until it stall the engine, i remove the red n black wire from the battery n put them on back it would reboot n start but it still happen again. I'm going to call holley tomorrow about this issue.

[whysohigh]

The website is completely different now. There's no support tab and nothing comes up searching for efi software.

If I just bought my Sniper EFI will it have the newest firmware?
