That probably depends on what you feel is "considerable". My best guess is that 13.8 V from the 48 V system, with the Tesla switching running, along with the necessary buck converter, best case efficiency is perhaps 90%. Via the 120 V system, maybe 80%. That seems significant, but if you're...

Agree, I hear no difference, even with no audio playing. And perhaps it's my imagination, but I feel that the volume of music is lower now, for a given volume setting position...?

On its way to me. Reading the fine print, I think the original one is radio-noisy and would cause interference beyond what is acceptable in Canada. Nothing wrong with them otherwise I suspect, so a good backup to keep around.

And also, I suspect that the 48V system would also be powered/charged from some sort of inverter. There might not be much difference between 120V and 48V systems when vampire loss is considered.

I'll be interested to hear if you start noticing weaker signals are noisier and weaker than they should be. My FT-8800 has the body under the driver's seat and the head is under the screen. In my case, I used an under screen shelf that I reinforced with a bit of metal between the rubber...

That tire is a show-er not a grow-er. I don't think deflating it will allow much shrinkage.

I'd have to say that tires are going to make a bigger difference than any torque vectoring feature. This is not a metric I'd use to make a purchasing decision.

OP described CB range accurately. In my case, I'm using a dual band VHF/UHF radio that will put out 50 watts. The antenna I'm using sits on the edge of the frunk lid and is only about 2 ft tall. With that arrangement, depending on location and terrain, I manage significantly greater distances...

I had them check them last summer. They said the seats were operating as designed and pretty much admitted they sucked.

Really? I can't actually be sure mine are operating, except for the change in fan noise.

This 'sounds' 😎 like a far from trivial problem to solve. Easy enough with headphones or earbuds because the sensing microphone is right at your ear and all you really need to do is flip the arriving sound wave 180° to cancel it out. But when the microphones are elsewhere in the vehicle and your...

I've discussed some of my thinking on the noise issue in other threads. The inverter that produces 120 volts does seem to be noisy. So much so that I now use a lithium iron phosphate battery to power my VHF/UHF radio. The inverter only needs to on, to generate noise - I don't even need to put a...

You would think so, but I'm starting to realize that there needs to be plenty of bonding done before that becomes the case. An electrical ground doesn't always mean an effective RF ground. And common mode noise might also be a problem. I've ordered a bunch of snap on ferrites to see if it's...

Yeah, accessories for the CT are typically priced in the you-must-think-I'm-an-idiot range. I've lost count of the number of times I've actually LOL'd for real.

I think you said you've been in the Tesla ecosystem since 2016? If so, then you have probably seen plenty of "promises" broken over the years, mostly comments from Elon on earnings calls and technology days. That's been a criticism from naysayers from Day One and I absolutely get it. But in...

I'd wager that they were simply made to look like an OEM AM/FM antenna. If the AM/FM radio remained functional, it likely used an antenna in the glass, or similar, because connecting both it and the VHF transceiver would have toasted the car radio the first time the transceiver transmitted...for...

This is completely wrong. Antennas are passive devices and the modulation type is irrelevant to the antenna. What is correct is the frequencies typically used by the two modes are quite different. Nominally 1 MHz for AM, 100 MHz for FM. Antennas are typically cut for the intended frequency, but...

Full stops were programmed in quite a while ago, because the government got sticky about it. If you were using HW3 in the Y, you weren't using the same FSD firmware that's in the truck (and HW4 vehicles). After 4000 km of V14, I'm at 90% usage. And that's here in Canada, on snow covered roads...

Same thing, likely. I glanced around after to see if anyone had seen my epileptic seizure... 😜

Except you're forgetting the other half of the equation. For the cheap AM radio receiver to work, there is still the requirement for transmitters all over the country that are either in operation (likely at a financial loss) or kept reading to be powered up at short notice. And it's also...
