Jebinc’s Plaid Vibration Experiment Results!!!

[bkcyk]

I’ve had the 35 to 40 mph cold start only vibes from new. Zero vibes otherwise.

44 update hasn’t changed a thing on my 7-8 month old MSP. Buttery smooth.

Took the vibrating mid 2021 Plaid out for the first time since 44.30.7 installation yesterday.... It was about a 15 mile round trip. For the most part, no real vibration in the typical zone of 38-48 (low or med height), but there is still a muted vibration (mostly at med height) in the mid to upper 50's. Once above 62, there is no vibration. Would love for others to test for vibration in the 50's at low and med height settings. Not sure if the improvements stem from randomness, or if 44.30.7 had a fix for those left out, previously. Perhaps some of the older COVID build cars had different inverters or suppliers. Who knows....

That's promising! I only really care about the low height. I'd leave mine on low all the time.

Plaid Vibration around 38-42MPH....

For those that my recall my early report, just after installing 2023.44.30.5.1 (Holiday Update), I reported the "frequency change" of the vibration and that it (for me) has moved up 10 mph. https://teslamotorsclub.com/tmc/threads/plaid-vibration-around-38-42mph.233411/page-79#post-7988837...

Thanks. Just replied. Based on that post it's not even close to proof they didn't cut total power under some part of the curve. Not until I see a speed/power graph before and after.

@Muzzman1 already took logs under full power. Still doing high 700s kW power.

Tesla isn’t going to wreck their reputation over this. I mean, sure, you can choose to believe they would, but… na.

Peak power means nothing. The logs for my MXP with battery ready mode and 90% SOC peaked at 845 kw. Unless I see a graph of power and speed, you can't be sure they didn't pull power from somewhere in the curve....like where it will prevent the cv joints from bending when bearing races are already distorted. Since the Plaid is already traction limited where this happens, full battery power isn't even a thing yet but taking power from the front and putting it to the back seems very unlikely since all 4 wheels are already traction limited.

 

[Muzzman1]

Let me know what sort of telemetry you'd like me to get for you via draggy, via TesLAX etc. Happy to help
Here's a 0-90 rip at 70% SOC. The car was not lacking in power in any way. FYI this was on a road in "Mexico", with some wet spots, so there was some traction control happening during the run.

I thought his chart showed peak power at 716.5 kW.

Look at his SoC…

Also look at the little 759.5 on that same graph. That was the max during the logging session. Also what @WilliamG said of course my SOC was below my daily charge point of 70%. I rarely charge more.

Common sense?

Hopefully Tesla learned from their mistakes with "launch gate" and the P90DL. I remember that one and had one of the affected cars with the "launch counter" where they took away power after too many launches.

I'm sure Tesla Plaid Channel installs his updates and would report back a sudden change in quarter mile times. Can we stop reaching for straws?

Yeah, I'm saying it isn't likely that they pulled power. There were a lot of angry customers the last time they did that. Plus, it wouldn't help anyway, since this problem happens at light loads.

You were apparently not around for 691 Gate or Charge Gate.

Oh yea. Forgot about that one. The had to replace nearly all v1 90s eventually with v3s.

Oh yeah. I had a v1 90 kwhr pack car that got throttled. I eventually got the full power back. But, my pack didn't fail before I turned in the lease in 2018.

V1 was a 1500 amp pack. V3 was 1600 amps. Tesla never once advertised the massive increase in power.... not until the 1680 amp 100 kwh battery (when used in the p100d.

And now 2300 amps in the Plaid, pretty wild!
