Some observations on v2.32.23. I upgraded to this version last night from 2.28.19.
Autopilot
This is the best version I've seen in several months. I know the actual AP module wasn't updated, but whatever other algorithms they've tweaked have made a marked difference. The lane keeping is tighter and more accurate. Sensing of the lane lines appears to be improved, including in marginal conditions such as faded or poorly striped lanes. I had been having difficulty with detection of solid yellow lines on the left side of the left lane, that appears to be improved as well, but not perfect.
I was brave enough today to allow AP to take a freeway interconnecting ramp from southbound Sam Houston Tollway (Beltway 8) to westbound Katy Freeway (I-10). TACC slowed the car on the ramp, and AP kept it between the lane lines without intervention, completed the turn on the interconnecting ramp, and then TACC sped back up to set speed as it was entering the freeway. I don't think any version of AP I've seen before could have managed this.
There appears to be a new, higher threshold for engaging AP. I was driving on Hwy 99 (Grand Parkway) this afternoon in light rain with AP engaged, and the rain turned heavy. I disengaged AP and drove manually. I noticed in the instrument cluster that the lane lines were now only being detected at the "black line" level, which is a step lower in confidence than the "black+gray line" level. AP would not let me reengage under this condition. I have not seen this behavior before. Prior to this, AP would let you engage in most low confidence situations.
Here is a shot of the IC while driving with TACC only in heavy rain. Note that the lane lines are only detected at the "black line" level, and the AP steering wheel icon is not present, indicating that AP cannot be engaged.
Two minutes later the heavy rain cleared and the gray+black lane lines came back, along with the ability to reengage AP:
Audio / Dolby
I have the Ultra HiFi Sound package, and I've always been pretty disappointed in its performance. While the sound is clear and has plenty of bass, the sound stage is very front-heavy with virtually no presence in the rear, and the imaging just blows. All sound always sounds like it's coming from directly behind the main display, with virtually no stereo separation. Mid-range and mid-bass notes are muddled and lack definition. I have always run the system with Dolby Surround turned off because it affects bass output too much.
After this update, I tried with Dolby Surround turned on and there is a marked improvement in the sound. For the first time, there is some stereo imaging and somewhat of a soundstage presence. Here are my settings:
I've also gone into the Slacker account that Tesla provided with the car (e-mail
[email protected] if you need to get it) and switched the feed to 320 Kbps high quality. That's a marked improvement in sound quality right there, and this update jacks it up another notch.
I still don't feel that the sound system is that good, the stock audio system I had in my Audi A6 was vastly superior. You shouldn't need DSP processing to make the sound imaging and staging come out -- that indicates that the system itself is of an inferior design and the DSP processing is a band-aid. Nevertheless, any improvement is welcome.
I haven't yet noticed any other major items that have changed in this version, but I will post them here if I see them.
