This was more helpful than volleys own video form five years ago thank you

[@kamasklassics]

Thank you. I understand because I, too, had to figure it out from their video.

[@sgtray717]

Thanks I successfully updated my sniper system using you video.

[@kamasklassics]

Great. We are happy to help where we can.

Can you please assist me. What can be the problem I did exactly what you did. Put it does not show the file for us to select it on the hand held unit. Everything is on the SD card.

[@kamasklassics]

It is extremely hard to troubleshoot without seeing it. Your best bet is to reach out to holley tech support.

[@Mindset-hs9be]

@kamasklassics thanks

[@billybobjoephil]

What do you suppose is on the update(s)? Anything noticeable with tuning or drivability?

[@kamasklassics]

It depends on which system it is. The sniper system is pretty basic, so maybe some updated algorithms to improve the constant learning. Other systems there are usually some big changes like support for more components or power adders.

Interesting. Yeah, I’ve been running a sniper for a while. I just wasn’t sure if it’s worth messing with. Thanks for the information

Hi. It seems you only updated the firmware on the handheld but not on the ECU. According to the instructions, after you update and reboot the handheld you should navigate to the ECU HW/FW button and upgrade the ECU... Please correct me if I'm wrong.

[@kamasklassics]

Starting at about 6:30 ot ran the ECU update.

I know I'ma sound dumb but how do I get it back to the cars readouts like back to the tps afr and everything can't get mine to go back

[@kamasklassics]

You definitely are not dumb. I work in IT as my everyday job, so I am very techy, and I struggle to find things in the system. Wherever you are, you should be able to press the home button and get to the main menu. You should see Tuning and Monitor if you are at the main menu. Go into Monitor. I believe what you are looking for is the one that says Multi-Gauge. Click it, and then from the next menu, you are probably looking for the Sensors or Air/Fuel Ratio gauge. Both have good info, so it depends on what you are looking for.
