Good to know. Thanks. What about smoothness of lane changes and cruise control, any difference there?Yes I have 16 Mx 90 that got the mcu2 upgrade with fsd. Vehicle displays cars in blind spots faster ... nearly instant (still not instant) where as before was a definite lag. Also displays many more objects. Not to mention able to utilize side cameras on reverse now and visualize side cameras plus all the other mcu2 bonus. This was when I already had the new hw3 fsd computer as well.
I did not notice smoother lane change (it was already fine) or improved cruise control (TACC).Good to know. Thanks. What about smoothness of lane changes and cruise control, any difference there?
It is better bc response time of the car is faster but it wasn’t that bad before. It adjusts faster to cars changing lanes which improves its response times but the actual lane changes itself is the sameGood to know. Thanks.

No. I got the HW3 when it was discounted to 2k. It is way more now. Like 8-10k.
$2500 only gets you the Infotainment (MCU2) upgrade, not FSD (HW3).
Another unexpected bonus from the upgrade: vampire drain is pretty much gone.
Ever since i have monitored the stats (fall 2019) with Teslamate, I noticed that the X very rarely went to sleep and vampire drain was about 1km per hour. I wasn't sure if this was normal or not as the forums have experiences all over the place. But since the upgrade, the car goes to sleep quite often and occasionally also goes offline. Not sure what the difference is between the tow in teslamate but I do know that vampire drain is now under 0.1km / hour. Quite a noticeable difference especially when I am not driving much these days. I was losing about 5-10% SOC per day before the upgrade and now it is 0-1% per day.

Perhaps some default settings were changed with summon or something but whatever the cause, I am very happy with this surprise benefit.
My situation also. I haven't upgraded to MCU2 yet but will do so ASAP. Clearly worth the investment!Do you have FSD? Because if you do then HW3 is free because it is part of the upgrade for the FSD. My advisor told me I'd only have to pay $2500 for the MCU2/hw3 upgrade. I have FSD.

Yeah I was told that with EAP (which I had) the MCU2 upgrade would put HW3 too. However multiple checks with Tesla corporate confirmed they do not put the HW3 in with MCU2. Further verified by Tesla Service installers. Folks will figure that out later when the new FSD features (which are not released yet) don't work. There is a reason why they charge separate for the HW3 and the MCU2 upgrades. Currently "FSD" software will work on AP2 and AP2.5 hardware which is why folks think they got HW3 with the MCU2 upgrade. The FSD term is misleading.
Well, I spoke with an employee in the service department and he did verify that if I decide to upgrade to MCU2, it will include a new LCD and hw3 as well for $2500. I have fsd, I did not ask whether the price is different for people without FSD.
hi guys i have a 2017 MX 75D. how do i tell which HW and MCU version the car is on?
