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

@kamasklassics 10 месяцев назад

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

Hopefully I can update using my MacBook Pro?

Any videos on how to check the logs for why My car was stalling out while driving, then it starts up again but runs rough for a few mins then is ok. Seems like a fuel constraint maybe or something with my Sniper.

Why didn't you save your most current tune off the sniper before pulling you card out? If you install the update it will write over you current tune, I saw you had a sniper file but that wasn't the most current file that would have been in your sniper.

Hola. Do you have any ideas why I don't have spark? Everything works,I have rpm. The white wire has a power distributor rotate. I think it is the ecu.

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 7 месяцев назад

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

I hate to be a hater. But compared to the holly video.This was a joke. Plus this video is from 8 mouths ago. Your not even Uploading the 2.0 and 10 mouths ago they came out with 3.0. For those that found this helpful bully for you.For those that didn't just go to the holly site. I've never even turned a laptop on before and it was simple for me. Why am I here? Wondering if I had to resave and rename tune to go from 2.0 to 3.0

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

@kamasklassics 9 месяцев назад

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

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 11 месяцев назад

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.
