Tesla MCU1 to MCU2 retrofit and FSD upgrade insights shared by Model S owner
Tesla recently started offering the option of upgrading the company’s older MCU1 units to an MCU2, which provides access to new features such as Sentry Mode and Tesla Theater. The process involved in this upgrade was recently shared by an owner of a 2017 Tesla Model S, who recently opted to purchase the MCU2 retrofit together with a Hardware 3 update.
Akikiki of the Tesla Motors Club forum gave details of the experience and the changes in his vehicle’s performance and features thanks to the hardware upgrades. The addition of MCU2 and Hardware 3 gave the Model S new features from the Full Self-Driving (FSD) suite’s Navigate on Autopilot feature, as well as the vehicle’s capability to visualize traffic lights, stop signs, and on-road markings.
The 2017 Model S “now has visualization that includes traffic lights, showing red, changing to green at the intersection,” Akikiki wrote. “As I drove under the light, they got larger showing green, until they disappeared as I went under them.”
The installation of the HW3 unit required for a recalibration of the Model S’ Autopilot system. The vehicle alerted Akikiki with a message on the vehicle’s Instrument Cluster (IC), stating, “CALIBRATION IN PROCESS.” The recalibration of Autopilot took ten miles total and allowed the driver to operate with Navigate on Autopilot, allowing the new visualizations to appear. The vehicle’s lane centering and steadiness while operating on Autopilot were reportedly improved with Hardware 3 installed.
Additionally, the Model S gained the ability to operate both Dashcam and Sentry Mode, both of which have been subjected to recent updates as recorded clips from both features can soon be viewed within the vehicle. Watching recorded clips in the car was previously not possible, but CEO Elon Musk and his team of engineers added the function with a recent update.
Additional features included a new WiFi card in the MCU2 that supports both 2.4 and 5GHz internet speeds, along with the vehicle’s internet browser, Tesla Theater, and Tesla Arcade.
The invoice states that the upgraded features of the Model S required Akikiki to pay a total of $2,500, all of which can be attributed to the MCU2 upgrade. The HW3 upgrade was free of charge because Akikiki purchased the FSD suite, qualifying him for a free HW3 retrofit, as per Elon Musk’s tweet back in October 2018.
Initially, Akikiki considered merely replacing the MCU1 chip, but he found that the upgrade would be just $1,000 less than the full MCU2 upgrade. “Although under warranty, the MCUs eMMC would still have the same size chip and would likely have another short life,” he said. “Out of warranty MCU1 repair would cost by today’s cost at least $1700+ including Tax. MCU2 cost is only $1,000 more than the MCU1 replacement and, in my opinion, is worth double that difference for longer life, better performance of AP and NAV plus the addition of Tesla Dashcam and Sentry.”
Older Tesla vehicles are being upgraded, so owners can experience the newest pieces of the company’s technology without having to buy a whole new car. For the Model S owner, his 2017 sedan now runs on the same hardware that Tesla’s latest vehicles operate on, giving it full range to drive and maneuver with the help of the company’s FSD suite. Not only does this increase the value of an older car immediately for owners, but it also contributes to safer driving conditions for Tesla owners and other vehicles on the road.

California snubs Tesla in its newly passed EV incentive that favors Rivian and Lucid
California passed a $135 million EV incentive that rewards Rivian and Lucid while sidelining Tesla
California just drew a line in the EV incentive sand to put Tesla on the wrong side of it. The state recently passed a $135 million program offering first-time electric vehicle buyers a direct incentive with no application required, but the rules were written in a way that leaves Tesla at a structural disadvantage compared to Rivian and Lucid.
The program caps eligible vehicles at $50,000 for new EVs and $25,000 for used ones. That pricing threshold rules out a significant portion of Tesla’s lineup, though some lower-priced Model 3 and Model Y configurations would still qualify. California-based automakers are exempt from the price cap entirely, regardless of what their vehicles cost. Rivian, headquartered in Irvine, and Lucid, based in the San Francisco Bay Area, both benefit from that exemption. Rivian’s R2 starts at roughly $45,000 but has versions above the cap. Lucid’s Air and Gravity start at $70,990 and $79,990 respectively, well above any threshold a non-California company would face.
California hits Tesla Cybercab and Robotaxi driverless cars with new law
Tesla built its reputation and a significant portion of its early market share in California, where EV adoption has consistently led the nation. The company operates its original factory in Fremont, California, and the state was home to Tesla’s headquarters for most of its existence. That changed in 2021 when Tesla moved its corporate headquarters to Austin, Texas. Since then, the relationship between the company and California Governor Gavin Newsom has been openly adversarial, with Musk and Newsom trading public criticism on multiple occasions.
California’s EV incentive landscape has shifted repeatedly in recent years, and Tesla has previously lost eligibility for state-level programs as its vehicles exceeded income-adjusted price thresholds. The federal $7,500 EV tax credit, which Tesla models have qualified for and lost depending on policy cycles, is no longer available after it expired without renewal, making state-level programs more meaningful to buyers than they have been in years.
The practical impact for buyers is more nuanced than the headline suggests. California residents purchasing a Tesla under $50,000 for the first time can still access the incentive. But the exemption written for California-based manufacturers is a structural advantage that rewards where a company plants its headquarters flag rather than where it builds its products, and Tesla moved that flag to Texas.

SpaceX’s newest logo confirms everything about what it’s become
SpaceX officially absorbed xAI under the SpaceXAI brand, completing the largest private merger in history.
SpaceX made its corporate transformation official in May 2026 when Elon Musk posted on X that xAI would cease to exist as a standalone company. “xAI will be dissolved as a separate company, so it will just be SpaceXAI, the AI products from SpaceX,” he wrote.
A new SpaceXAI logo was announced today, visually embedding the xAI letters inside the SpaceX identity, which can be seen as a deliberate design choice that signals the merger is not a partnership but a full absorption and XAi a core function of the same company. The same way Starlink is not a separate brand but a SpaceX product. The announcement closed the loop on a process that began February 2, 2026, when SpaceX acquired xAI in the largest private merger in history, valued at $1.25 trillion. SpaceX at $1 trillion and xAI at $250 billion.

The reason SpaceX bought xAI was stated plainly by Musk at the time of the deal: to build orbital data centers. SpaceX had simultaneously filed with the FCC to launch up to one million satellites designed to function as AI compute nodes in low Earth orbit, escaping what Musk described as the energy constraints limiting AI development on Earth.
xAI provided the AI software stack, with Grok, the X platform, and the Colossus supercomputer infrastructure in Memphis with over 220,000 NVIDIA GPUs, while SpaceX provided the rockets, Starlink, and the capital base to fund it. The two companies needed each other. xAI was burning $2.5 billion in losses on $250 million in revenue. SpaceX was generating an estimated $8 billion in profit on $15 billion in revenue and needed an AI narrative to command the valuation it was targeting for its IPO.
What SpaceX has done, regardless of how the orbital AI vision ultimately plays out, is walk into a public market as something no company has been before: a rocket manufacturer, satellite internet provider, AI software company, social media platform, and supercomputer operator under one ticker. Whether that combination is worth $2 trillion depends entirely on which of those businesses you believe in most.
Tesla brought its innovative Cybercab robotaxi to the National Federation of the Blind (NFB) Annual Convention in Austin, Texas, on July 3 at the JW Marriott Austin.

The showcase emphasized practical features tailored to the needs of the blind community. Braille lettering appears on physical controls, including door releases and emergency buttons, allowing users to navigate interfaces independently through touch. Generous interior space accommodates service animals and assistive devices such as canes, guide dogs, or mobility aids without compromising comfort.
Wheelchair-height seating facilitates easier transfers for users with additional mobility challenges. Photos from the event captured blind attendees approaching the vehicle confidently, service dogs relaxing inside, and hands exploring Braille-equipped handles.
Tesla Robotaxi’s official account detailed these elements, noting the Cybercab’s focus on accessibility, especially noting the Braille lettering and additional space for service animals.
How Tesla Will Transform Mobility for the Blind
Autonomous vehicles like the Cybercab promise revolutionary independence for the roughly 2.2 million visually impaired Americans. Traditional barriers—reliance on sighted drivers, costly paratransit, or limited public transit—often restrict spontaneous travel. Tesla Full Self-Driving aims to eliminate the need for a human operator, enabling on-demand, door-to-door rides via simple app hailing with voice guidance.
Users gain freedom to work, socialize, shop, or attend events anytime without scheduling hassles or safety concerns. This reduces isolation, boosts employment opportunities, and enhances quality of life, turning mobility from a dependency into true personal autonomy.
The NFB demonstration not only gathered valuable feedback but also generated excitement about a future where technology levels the playing field. By prioritizing inclusive design, Tesla advances a vision of transportation that serves everyone, potentially reshaping daily life for blind individuals and setting a standard for the autonomous industry.
As Cybercab deployment scales, these accessibility innovations could mark a significant step toward equitable mobility.
