    Tech Forum - many informative YouTube clips by Model 3 owner

    Matt Shumaker is a technical guy; YouTube since 2007 "Interesting projects and reviews of cutting edge products" seems self-employed; claims he is NOT a fanboy and NOT a tree hugger. He offers a fresh perspective from a technical car guy point of view Civic Si is just one of his cars. Seems to...

    My Analysis and Explanation of Tesla's Battery Pack

    PEM Fans

    Purchased a 2.5 Sport in November. Love the car. The best irrational thing I have ever done! OK... that being said a week ago had to have the Roadster towed to the Tesla shop as the dreaded Error 1144 PEM overheating error popped up. Diagnosis is - needs 2 new PEM fans - better than a new PEM...

    Processing Speed of Touchscreen in Model X/S vs. Model 3

    This video is a great comparison of the processing speed of the touchscreen in Model X/S versus Model 3. When averaging the speed of different tasks on each model, the Model 3 average 4.44x faster than Model X/S. Given that Model X/S are considerably more expensive than the Model 3, the...

    What to expect during a software update

    I did some looking around and didn’t see an example of a software update progressing through its various stages. I apologize if this is out there and I just missed it. My observation might be helpful for those buying a used Model S or X and the general idea depicted here applies to Model 3 as...

    Rebuilders: Need a replacement rear subframe?

    I have a slightly damaged rear steel subframe for the Roadster (1.5 if they differ) and I'm wondering if any of you folks who are rebuilding cars would want it. It was replaced a few years ago when my car took a hit on the left rear wheel. The rear suspension members bent and the only damage I...

    Logged data on SD card?

    I know Tesla has a method of saving driving logs onto an SD card in the MCU. Do you have, or have you seen, what is on the SD cards? I know one is navigation.

    I have noticed that if your phone is connected to BLUETOOTH and you are receiving your calls in your car, IF you then use your phone for a TEXT, the car will show YOUR personal phone number and then it cannot be deleted.

    Tesla Model 3 Blackvue 750 2ch DIY install with Constant 12V power

    Help me understand this AP feature

    I don't understand why AP turns off if you keep hands off the wheel. Wouldn’t it be safer to play persistent tones that get louder until you grab the wheel? If a driver is asleep or unconscious, and AP turns off, that’s a sure-fired way to wreck in 30 seconds. If AP stays on, there’s a much...
