Successful retrofit of passenger lumbar on 2021 Model Y

[zikronix]

That's bullshit, just because the car doesn't "support" lumbar doesn't mean we shouldn't have the ability to retrofit. Every car in history has been modified to death.

It is bullshit because it worked.

It is bull *sugar* because it worked.

Exactly! hahaha. Passenger-side lumbar is still working on my car since the most recent update hasn't been pushed to my car. I had my girlfriend set her lumbar setting prior to the update being pushed.

They aren't stopping you from modifying your car, you just can't use their lumbar parts to do it.

I think it is stupid of them to do this, they really should have retrofit options like this available. (So that the limited parts go to people that will use them and are willing to pay for them.)

So frustrating.

While aftermarket companies are making auto frunk, auto doors, auto presenting door handles and who knows what else, we are getting boned trying to instal OEM parts to retain a function. We really do need someone with online presence to tweet elon.

Pretty sure it’s not coming back guys. It’s build based off this config. The service center couldn’t roll back. Let’s get a petition going

So does lumbar/seat control have its own ECU? Wonder if we just swap that if they can’t enable it with our “incompatible” ECU?

Apparently?

People have paid for the parts, they're OEM.... I dont see the issue.

Man, this really sours the idea of a HEPA retrofit for me.

I’m going to give it awhile before I reach back out to service; but I’m curious to know where the ECU is and what the cost would be on one that supports dual lumbar. Looks like it’s a part that can be bought over the counter without a specific vin

It isn't just a matter of having the correct ECU, which a lot of people have, it is a matter of the car having the configuration that says you have an ECU that supports both. And Tesla doesn't allow the configuration to be changed, even by their own service techs. (They even have a Teleforce bot that checks the configuration remotely and corrects it if it gets "corrupted".)

 

[Grandpa Gebis]

Considering they can change configuration for other things, I guess I assumed you could swap the ECU, update the config and be set. Guess I’ll just have to deal with it set where it’s at and hope for the unlikely reenabling.

This, it has to be an official tesla retro fit for that flag to be changed. You can get ballsy and hot jump the switch.

 

[Grandpa Gebis]

Just had the number installed by the service center. Cost $320.

Assuming you are on 2022.4.5; does your lumbar still work?

I retweeted you and liked it. Hopefully, we can get some traction here.

I have a mobile appt tomorrow. Going to say I don’t know why it stopped working and see what can be done.

Fingers crossed

Any update?

 

[Grandpa Gebis]

Not that I expected it to work, but I installed 2022.4.5.3 today, still no lumbar

 

[zikronix]

welp, i think this is the end of the road for this unless it becomes official tesla retrofit. If someone wants to setup a petition thats a lot more professional then me, I'll sign it.
