    Does Tesla have a big math problem?

    If the motor cycle is coming directly towards you, say at 60 mph, and you want to turn right into it’s path, I don’t think 4 pixels at 160m is close to being enough to get an accurate enough velocity vector to make a safe maneuver. The motorcycle is upon you in about 5 seconds

    HULU ERROR p-dev302

    I found Hulu chat support very unhelpful. They promised someone would call "right away" but they never did.

    Raven Half Shaft Replacement

    I'm curious if anyone knows whether or not the shudder issue has been fixed on the revised S. If it's caused by repeated hard acceleration you would think that the Plaid, in particular, would be more prone to this.

    Raven Half Shaft Replacement

    That's what I was hoping. (Previously owned a 100D that exhibited the shudder). New half shafts to be fitted soon.

    Reduced torque after half shaft and clevis mount replacement to fix acceleration judder/rattle?

    I'll be having my half shafts replaced soon. Does anyone know if this widespread shudder issue has been resolved yet by Tesla, with an improved design?

    Unhappy with FSD sales and pricing

    I fully agree. As a shareholder and 2x vehicle owner I'm worried that Elon's dangling carrot business growth technique is soon going to backfire.

    Do you have shudder on hard acceleration? AKA death rattle?

    Yes, it's definitely embarrassing and a little worrying that after several years of owners reporting this, they still don't have a fix. Hopefully the warmer weather will take care of it temporarily for you eventually.

    Very interesting. Thanks for posting. So apparently it didn't get faster after the 2020.20.5 update.

    Do you have shudder on hard acceleration? AKA death rattle?

    My fear is that by the time I take the car to the SC, the weather will be warm enough for the problem to be not evident. I'm delaying my appointment because of the Covid risk.

    Do you have shudder on hard acceleration? AKA death rattle?

    My car was manufactured after the date of this bulletin, which refers to "older versions ....". .... but I do believe the noise is coming from the left side.

    Do you have shudder on hard acceleration? AKA death rattle?

    Mine rattles on low suspension setting.

    Do you have shudder on hard acceleration? AKA death rattle?

    It went away on my 2018 100D when the warmer weather arrived last year. I traded it in for a Raven LR last August and the death rattle on that vehicle started in November or so. I booked a service appointment for it fairly recently but because of the virus am delaying until it's safer to take...

    Raven long range real world 0-60

    If you take a look at my posts here Raven (non-performance) Maximum Power Output vs 100D on September 27, 2019, you will see my graphs from Powertools. I think your car is faster in the above than mine was then. It's been several months since I made a Powertools run. If you extrapolate the...

    Indeed. No Cheetah Mode of course but it would be interesting to find out if the LR also received more power, or off-the-line torque with the latest update.

    Raven (non-performance) Maximum Power Output vs 100D

    My suspicion is that my car is faster after the new 2020.20.5 update. Took it for a quick spin yesterday on <30% SOC (yes that low) and the pull at low speeds felt sharper. Just subjective at this point as I have no roads around here to fully put it to the test. Would be interested to hear other...

    Raven (non-performance) Maximum Power Output vs 100D

    Nothing new I'm afraid. I was told my car is performing "normally". Still waiting (hoping) for OTA peak HP increase to bring car in line with what was achievable with my old (early 2018) 100D. I think I can conclude that the Raven LR has slightly faster acceleration off the line and up to...

    Do you have shudder on hard acceleration? AKA death rattle?

    Definitely appears to be temperature related. Had this start on my 100D when the weather turned cold and it stopped as weather warmed up. My August 2019 LR Raven started making the same noise on hard acceleration (even when suspension set to Low) around November. I haven’t reported it to SC...

    Raven (non-performance) Maximum Power Output vs 100D

    The next software update will include a power increase (of about 3% for the Model S?). It will be interesting to see exactly how the Raven’s new power output curve will compare with the 100D shown here.

    Regen braking dramatically reduced.

    Mine is a MS Long Range built around the same time. Regen will be limited if the batteries are cold. Interestingly though, I have noticed less regen since the latest update even when the ambient is in the high 50s or even >60F.

    Raven (non-performance) Maximum Power Output vs 100D

    Doppler signals are dynamically affected by atmospherics. Velocity from Doppler is integrated to determine position. Position is therefore also influenced in a dynamic way by atmospherics, unless you are using DGPS, which you confirmed Dragy is not.
  28. DavidO

    Raven (non-performance) Maximum Power Output vs 100D

    Again, we need to analyze the dynamic performance of the instrument which according to this site: How Does DGPS (Differential GPS) Work? . is affected by atmospherics. Doppler is affected by atmospherics too: "The ionosphere will add a relatively large delay, the actual number depends on...

    Raven (non-performance) Maximum Power Output vs 100D

    Thanks for the info but does Dragy have one antenna or two? It is only with the two antenna version that VBOX3i is able to achieve such precision. Otherwise the resolution is 80cm even with a DGPS base station which is far longer than the <1ft resolution needed to analyze what is happening in...

    Acceleration in Raven Model X slower than advertised.. Any explanation

    You might also like to check out the following thread: Raven (non-performance) Maximum Power Output vs 100D I plan to do another 0-60 PowerTools run with my S Raven long range this weekend. Latest software and suspension set to low. My Raven feels a little slower than my 2018 100D did above...

    I think by time 0.0 in the above graphs the 1 ft rollout has long since passed. From my Excel-generated graphs I've estimated a 0.45s rollout.

    Summon Question

    I've noticed during Summon that my car backs up first if there's nothing behind it, presumably so that the cameras can see if there is an obstacle in the way, such as a parking curb in front of the wheels, before proceeding forwards. I haven't had any instances where it did not recognize and...

    Charging my Raven Model X at a Version 3 supercharger

    I'm looking at a photo I took in my Raven Long Range at a V2 SuperCharger the other day showing 143 kW (529 mi/hr) @ 34% of charge. I'm sure I've seen it as high as the 540s mi/hr at one other time.

    Raven (non-performance) Maximum Power Output vs 100D

    Very nice! I think the fastest run I had with my 100D was a 3.625 but I was using "tracking" and doing my own analysis as to when the car first starts moving. Were you using tracking or the "0-60" function? For some reason I've never been able to get that feature to work.

    Raven (non-performance) Maximum Power Output vs 100D

    Point I'm making is that while I have no doubt Dragy is accurate from a dead stop to 60, 1/8 mile 1/4 mile etc (GPS resolution has no significant effect in this case), where it does matter is in determining the all-important time to roll that first foot. Does it use L1C or L2C GPS receivers...

    Raven (non-performance) Maximum Power Output vs 100D

    What is the GPS resolution and accuracy of a Dragy GPS? Is it more accurate than the DoD has access to? And how does it determine (what is the science behind the determining of) the time to roll that first foot?
  39. DavidO

    Raven (non-performance) Maximum Power Output vs 100D

    I don't think Dragy would be any more accurate and certainly doesn't give an accurate 1ft rollout correction because it uses GPS, with insufficient resolution to see what's going on in the critical first foot of motion. In my opinion it appears that your car, like mine, is NOT in line IF...

    Raven (non-performance) Maximum Power Output vs 100D

    0-1 to 0-60 means you are missing that first mile-per-hour. The initial acceleration from my data over the first foot or so is 3 m/s/s. 1 mph is 0.44 m/s, so using an online calculator it takes 0.147 seconds to reach 1 mph at 3 m/s/s acceleration, so your 0-60 time comes in at 4.02s or 3.57s...
  41. DavidO

    Raven (non-performance) Maximum Power Output vs 100D

    Initial acceleration in the above graphs indicates approximately a 0.45s 1 ft rollout time. Dragy assumes 0.25s which I believe to be incorrect. PowerTools data illustrates the benefit of using rotational speed to determine acceleration vs GPS which clearly cannot analyze the first foot of...

    Raven (non-performance) Maximum Power Output vs 100D

    I believe there are standalone apps but I've never tried them and I don't know how accurate they would be. I'll be interested to hear how your test drive of the LR Raven went. Listen for traction control struggling to keep the tires gripping the first 20mph or so. The following graphs...

    Good question. I had the window down and my wife recorded audio. Did not hear any tire slip. The latest software update appeared to fix that issue with mine and other Long Range Ravens.

    Raven (non-performance) Maximum Power Output vs 100D

    Do you (or does anybody) happen to know if that Tesla quoted 3.7s 0-60 time is from a dead stop or is it the “1 foot rollout” spec? 1 foot rollout at the initial accelerations of the S Long Range is calculated to at least 0.25 seconds, so 3.7 could actually mean at least 3.95 from a dead stop...

    Raven (non-performance) Maximum Power Output vs 100D

    My goal was to compare experiences with my new Long Range Raven vs my 2018 100D. I did not take any data at 90% from the 100D. Charging your Tesla could make a difference of 40% to power and acceleration suggests a small difference in acceleration even when going from 75% to 100%. Also see...
