    30 mph seems to be the lowest I can set the cruise control. It doesn't matter what gear I'm in. I forgot to mention that it's wiring harness also plugs into the odb2 port. It gets its speed from there and I guess the brake information as well.

    stevedmc has a manual transmission, so RPM will be the same (assuming stock tire size) as in:

    Correction. I think I've driven as low as 25 mph with cruise control. Doesn't really matter though unless you are just nitpicking.

    I ditched the stock tire size a long time ago. The stock tire size has very limited options and is expensive.

    Around 40k miles I switched to 175/65-14 and have never looked back. The speedometer/odometer difference is barely noticable. I think it is around 1 percent.

    Incidentally, I verified my Rostra cruise control speed isn't based on RPM with a very simply test.

    In fifth gear I set my speed with the cruise control to 55 mph. I drove for a moment and then tapped my brakes to disable the cruise control. I then put the vehicle into fourth gear and hit the resume button the the cruise control. It cruised at 55 mph.

    Thats a good enough test for me and it verifies that it is using a speed signal from the OBDII port and not RPM information.

    Of course - I should know that. I was too eager I guess.

    I'm the kind of person who, when I find a problem too challenging, I walk away from it...at least for a little while. Today, I revistied the problem with getting the ETACS decoder program working on my system. I found I had TOO MANY of the X-Horse drivers installed...apparently Windows doesn't prevent you from installing multiple instances of one driver, but when you do, none of them work. I deleted all of them. I also deleted the manufacturer specific drivers for my MVCI cable.

    I downloaded the latest version of the ETACS decoder program and THEIR driver for the MVCI cable and the X-Horse drivers.
    I tried to install the X-Horse drivers, but they woudn't install. I DID install the MVCI cable driver with no problems.

    I decided to go ahead and try running ETACS decoder and see what happens. It found the cable and I was able to set the COM port and CAN settings, no problem. But, the program was not able to connect to the server to log me in - my firewall was blocking it. I set the firewall to allow ETACS to communicate with the server and I still had 5 writes allowed.

    I hauled my computer out to my car, plugged the cable into the OBD port, turned on the ignition, and clicked the 'ON' button on the ETACS display. IT CONNECTED!!!! I then clicked on the 'Engine' tab and all the ETACS items were there; I scrolled down to the Cruise Control setting, changed it to 'Present', clicked on 'Write to ECU' and followed the pop-up instructions. IT WORKED!!!

    I disconnected my computer from my car, and took the car for a test drive...I HAVE CRUISE CONTROL!!! (But no horn).

    So, I'm happy. A little more tweaking to get the horn working and button everything back up; future plans to enable the fog lights, and disable the engine immobilizer; and maybe I'll just see what kind of trouble I can get into.

    Thank you DOAX, and others, for making this possible.

    Congratulations on your success. Looking forward to seeing what else you are able to change. I would be interested in seeing if anyone can change the three-blinker-blinks with a bump of the turn signal stalk from three to say, five.

    Woohoo, very glad to hear you got it figured out.

    They must have changed the wiring on the 2017+ models. The only other wires on my connector are for audio controls. The horn is on a different connector.
