What can you reprogram on a Taycan with the PWIS?
could you do something like unlock the full capacity for someone who got a J1.2 replacement battery in their J1.1?
So there are two things going on here. All related to the way Porsche manages regenerative braking, so first you need to understand how they do it differently. Sorry if this is pedantic, but just to understand what we're looking at.
Most EVs are set up for "one pedal driving", so the...
I still find the brakes to be the only major shortfall on these cars although for some reason, my car 2022 CT 4S with PSCB has always had issues while the 2020 Turbo that we had for my business never had a problem.
I still get the long travel and funky whiring sound as the servo pics up the...
I had one replaced under warranty. There was a low frequency hum at low speed, with a bit of steering input that at times would shake the car like a subwoofer. First they said they found the transmission fluid had leaked, so they stopped it up... the sound came back and I pointed out that if the...
Very exciting stuff. So in theory, applying this tech to a battery our size would take ~460lbs out of our cars... so a lighter car that will both be faster and more efficient with more range? Sign me up.
I get more of a deep bassy grown at low speeds with steering input... sounds like the rear brakes dragging or the diff fighting itself. Haven't been able to nail down the cause, but at one point Porsche replaced the entire rear drive unit and it went away, now it's back again.
Who knows.. maybe it will be like the steering wheel upgrade they offered to early PDK cars that an up/down button on each side instead of an up paddle on the right and down paddle on the left. They made it available and expensive and I know loads of people paid for it. The same could be true...
Yeah, when this new rain issue happened to me, the pedal did not go to the floor, I had to press on it a bit harder and the discs felt like they were doing very little, but then grabbed hard and made a horrible shudder / vibration.
If it's letting go entirely, I would have the dealer looking at...
Reading through that ^ again, I'm thinking what I did braking 5 times to a full stop in short succession somehow accellerated or reset the ‘Brake Refresh’ or Stiff Learning Routine’ functions [insert gutter jokes here]
The long pedal thing is covered here:

Not so much jamming on the brakes. It's tricky since to some extent, no matter how hard you brake the car slows 100% with regen until the last bit where you need to come to a complete stop. I belive in normal braking the regen stops and the discs take over <5mph. So with that, I pulled out of my...
I'll keep testing it, but I honestly feel like I've cracked it with the recent bedding procedure. When it first happened to the extent that I recently experienced, it was really bad, dangerous and annoying. I was ready to take the car back to Porsche and consider giving it back entirely, but it...
