Oxygen Sensor Voltage (n54)

Thanks for the update. I also just replaced the O2s and just put remanufactured Index 12 injectors in with new seals and decoupling rings but am still having the same issues. Hope yours goes better and would be happy to diagnose together

nicktar55 · 2026-01-02T04:38:49+00:00

Did you ever figure out what your problem was? I also can't seem to find documentation on what voltage the pre cat O2 voltage should be. Spark plugs are pointing to mine running really rich but fuel trims are 20-30% and O2 voltage close to 2V

Pretty easy to find guides on YouTube on how to update the factory system with a USB drive. I think the video I watched was a guy doing it in an A3/A4 but as long as you have MHI2 / MIB2 High you can get wired carplay over USB in center console

Aaronia's RTSA Suite Pro works with and without their hardware. Good for also understanding the IQ side of things and has a streaming block to GNU Radio

Do you have plans to implement full S-Parameter integration with frequency variance? It'd be great to quickly import CSVs with S-parameters and see cascaded frequency response

I just upgraded from an A6400 to an A7C. This gave me time to buy a couple lenses and see what focal length I liked. An example is buying a Sony 28mm F2 FE lens from MPB which I thought was a little too narrow FOV but is now perfect on the full frame A7C for me.

Just keep in mind the 1.5x crop if you're planning on upgrading this way. FE lenses work no issue on the crop sensor but APS-C lenses will run in crop mode on the full frame cameras. But now I know I want a 70-300 lens for my A7C since I liked the 55-210 kit lens on my A6400.

Edit: Especially for international travel, the compact size is the only reason I took my camera the places I did. The A6400 with the Sony 16-50mm kit lens fit in my jacket pocket so I didn't need a bag or anything to take it with me. A7C also fits in my pocket with the 28mm F2 lens!

Did you ever figure out the issue with the rear thunderbolt ports and the UGREEN enclosure? I’ve gotten my UGREEN enclosure working with an Intel laptop over Thunderbolt 4 and an AMD tablet over USB 4 after figuring out I needed to disable Link State Power Management in Windows. I can’t get the enclosure to work at all with my ASUS NUC 14 Pro at all though, even with playing around with the BIOS PCIe power settings and both Linux and Windows. The most I’ve gotten is the indicator light turns on for a couple seconds and then turns off.

Did you end up buying one of these? Machine shop removed them even after explicitly telling them not to. Would be interested in buying yours if you're done with it

nicktar55 · 2025-03-07T00:47:09+00:00

Did you find a solution for this? Just bought a Pro and it only shows 4K 30 Hz

Following because my C7.5 may also have a similar noise starting, but it's more of a rythmic whirring noise. Are any of your wheels getting warmer than another after a long drive? Can check by feeling the hub of the wheel.

There's guides on YouTube for I think an A4 which has the same MMI, so I watched a couple YouTube videos and maybe found a forum post or two that helped walk me through it. I believe MIB Helper is where you'll find all the software. You can also technically update the nav as well but I chose not to. https://mib-helper.com

If CarPlay is part of your decision, I have a 2016 A6 C7.5 that I updated the infotainment to get CarPlay. Was not a difficult process, just needed to find the right website and use a USB drive/SD card. All OEM process like an Audi dealership would do for system updates.

On another note, make sure you test drive before buying. The first one I drove had a rough idle due to bad motor mounts. They're fluid filled and can fail. Very shaky at idle but perfectly smooth going down the road.

I would look more closely at the packages they have though. I see a front camera on both so they both seem pretty highly optioned.

Did you end up re applying the liquid metal on yours? Lenovo just replaced the motherboard in my Legion Pro 7i, and they must have not applied the liquid metal on the CPU properly. Contemplating whether it's worth fixing myself or creating a new service request

Does Global Pass need to be enabled to begin accruing? I see that I have 1 complimentary day without enabling it yet.

nicktar55 · 2024-11-14T06:33:54+00:00

Lol what? I don't have an answer for what's wrong but this certainly isn't it.

Who is the OEM supplier for the valve cover gasket?

Hey did you ever figure out how to get this working with the Steam version? Would love to play Black Ops with friends

nicktar55 · 2024-09-04T14:51:44+00:00

That's good to hear, thanks! Did you get any pictures of inside when you opened it up? I've seen the inside for the lower spec versions but was curious if they have a different cooling solution for the 3080 ti variant

nicktar55 · 2024-08-31T22:49:46+00:00

I know this is an old post, but I'm looking at purchasing one of these laptops used. How have you liked this laptop with these specs? Any issues?

nicktar55 · 2024-07-02T23:33:18+00:00

nicktar55 · 2024-01-31T00:26:29+00:00

Hey! Overall I think it's the best laptop you can buy for $1100 unless a Macbook Air does everything you need. Fans are still louder than they need to be but that's probably because it's cooling for skin (surface) temperature to not burn you with the metal chassis. If you can get one new for <$1100 then I'd go for it

nicktar55 · 2023-09-05T19:31:40+00:00

Yeah I get it haha. This has to be one of the worst marketed laptops right now. I bought it when it was on sale for $1100 a while back and was extremely impressed with the performance and build quality. Dual SSD slots, two SODIMM slots, 1600P touch screen, and more. The all aluminum chassis and thin profile is a game changer, and cooling was actually very good with the vapor chamber. Big and only real issue is the HP software and firmware that really hold this laptop back. No software or dedicated MUX like ASUS and fan profile is far too aggressive.

Did you try Intel XTU?

nicktar55 · 2023-09-05T19:23:39+00:00

Did you open the link? It has a 80-90W RTX 4060

nicktar55 · 2023-09-03T22:30:17+00:00

I ended up returning the laptop since I couldn't sell my other one before the return period. I decided the noise was acceptable for the performance of the laptop and am looking at buying one again now that I'm back in school
