Latest firmware version for a 1.5 Roadster

[Msjulie]

Lowest I could set was 18mph just 10mins ago, first ever cruise control for me in this car

With the 3.7.1 53 firmware, I was able to activate cruise at 20mph. It's likely that it would also activate at the 18mph lower limit that @Msjulie tested.

My car just returned from the service center today, and still has the 3.6.12.

And you actually thought they would update it proactively without you asking for it?

Next time I'm in my Roadster I will test the cruise at 25 and let you know.

If you still have 3.6.12 firmware like most of us, it won't work. 30 has been the limit since the beginning, but now maybe the 3.6.16 firmware reduces it.

Thanks for performing the test. I'll get a firmware update scheduled.

As a long-time EV driver, I've come to use cruise control much of the time as a tool to improve range as well as to manage speed limits.

Great news. I had asked tesla for this years ago and they said not possible. Great to see that they snuck it in. Now, to get Tesla to update my car...

I missed the significance of your firmware version number when I read your post before -- I read it as the different number series for 2.x cars, but those firmware versions are 4.x.y. I had not noticed that as part of the 3.0 battery upgrade the 1.5 firmware is updated to 3.7.1. I had not looked closely at the VDS when turning on the car, and VMSParser still showed that my latest firmware was 3.6.12 from 2014. I believe a contributing factor for the new firmware update not being reported is that the records in the log file that were recorded during the upgrade procedure have bogus timestamps in the year 2033. I've mentioned that to Tom Saxton and am still digging into the information in the log file to learn more. So, I don't need a firmware update, I already have the new feature.

As part of the "3.0" ESS upgrade, my firmware was updated to 3.8.2.

I know this is an old thread but only Tesla can update the Firmware?

And can none 3.0 cars run the latest?

And max for the 1.5 is what?

I searched but couldn't figure out any of these answers.

Thanks for any replies in advance.

My 1.5/3.0 car is running 3.8.2 53.

Just back from service, my 1.5 is running Car FW 3.6.16 HW Pkg 17. (I can never prove it's the max.)
