Frunk Update Ruined Torque Delivery?

[bluxombie]

I just got this frunk update in my 23 lightning and now my truck is now massively nerfed.

I could take off from a dead stop and it was immediate power. Loved that.
This update has fkd that away.

There's a big delay even if I floor it. It feels like a 4 cylinder trying to catch up.
Straight hot garbage of an update.

It's a very slow ramp up to speed. This was bought with the speed and instant torque as one of the selling points.

Any way to revert updates? It's BS to nerf the power delivery. I'd like to go back to the previous update and turn off auto update since the updates are making the vehicle less useful... and we're nearly 2 years late for the new blue cruise update.

I have not experienced this in either the frunk or Bluecruise 1.4 updates.

Wow, haven't heard that ever happening before. Try disconnecting the low voltage battery for about 30 mins then check it again. Could just be a bug, could also be a bad lvb.

Well, I'm encouraged that it's just me.
I also had noticed in 1 pedal mode that my reverse didn't brake properly. I had to manually engage the brake when I have never had any issue with the one pedal braking like a champ forward and reverse. Forward was just fine.
But at least this isn't a wide spread thing or a nerf on the torque delivery. That's good news.

So it's just me and a one off then.
That is good.
I haven't gotten 1.4. I've been looking forward to that one.
Either way, it's good to hear others say they haven't had this issue.

You have to be prepared to go through every single user setting after an update because they will often revert to default. I have spent more than a few minutes wondering what a honk or a chime is about due to this. It's just the nature of the beast - OTA software updates in general and this truck in particular. Some things never change, like having the screen in dark mode always, to turning on the check rear seat warning.

For instance now it's honking after I lock it and walk away from it after the BC 1.4 update but I haven't been annoyed enough by it to go looking for the setting that controls that nuisance behavior.

I also think something has changed in regards to acceleration. I don't know when it happened but I have noticed a difference. When I first got my truck, I could spin my tires from a stand still. I could probably even spin them by punching it while already going 20 to 30 mph. Now with tires that are older (which should lose traction easier), I find it very hard to spin the tires. My truck is still insanely fast so I am not complaining but I do believe something changed in this regard. Maybe they lowered full output a bit or maybe they fine tuned traction control so wheels don't spin. As I said, its still crazy fast so I didn't thing anything of it or cared to look into it. But now I'm curious. Next time I take a drive, I'm going to try shutting traction control off and see if it makes a difference.

Can you provide more information?

Is this issue an ongoing problem? What is the SOC when the perceived low power happens? Are you showing full power available in the IP screen? How is the truck loaded; is there a bunch of stuff in the bed/frunk/cab?

A change in traction control is possible. If you hold the traction control button down for 10 seconds it will be turned off. BEWARE! 775 instant ft-lbs is not something most people have ever had access to. I tried it in the snow last year and it was basically undrivable.

Look at your available power meter, it happened once to me that only 50% was available after an ota for whatever reason, a while and ignition cycle later and all was back to normal

I was wondering about this myself. Mine will still losen the front tires up till about 45mph or so, but still midrange acceleration feels a bit slower. This gets worse once th le battery goes below 80% soc.

My guess is they may have lowered the max current, possibly to reduce the chances of high voltage contactor failure.

Same happened to me after the BC 1.4 update. GOM showed 51% available power. Drove it long enough to use some of the battery charge then plugged it in overnight. Next day, battery full at 90% and GOM showed 100% available power.

There has definitely been a change in traction control. I don't think this makes the truck slower. It just manages traction a bit better. Some of us had a pulsing in the power train when accelerating moderately following a traction control event and then accelerating to around 40-50 (around a corner or on wet roads is where I noticed it most). That is now gone.

For the OP - if your tires have less traction, the TCS system will reduce power to keep them from slipping. In your case, it seems like a more excessive power loss. Updates can affect things in different ways for different trucks across the modules and sometimes a few updates are applied following the documented immobilization update that can take a day or so. If you still have problems a day or two after the initial symptoms, you may want to do a 12V reset. This will get the modules all working together again with the new parameters. It also eliminates discrepancies that show in your Sync settings that may be inconsistent with the actual sets in the various modules.

I would do this an hour after you shut down for the day. This gives the truck time to complete any updates if they are in progress and most of the modules will be shut down by then.

I've noticed several of my own settings have changed since the 'frunk' update:

- the Frunk will now NOT open with the front button

- the 'auto locks' suddenly are back in play, when these are only FORSCAN settings

- the 'brake coach' nonsense is back

- Drive modes, Adaptive Cruise, and other driving tools don't seem to be affected


- the brand new iPhone 17 AIR , nestled in front of the new Rotary Dial, is working just fine, too, at least when I can find it - it's so thin I'm not sure if I'm actually seeing it, or it's just a 'mirage'... : )
